Our Guest Speaker - Earth Science Museum
January 2013 . Is in ASU’s Physical Science Building (PSF) room 123, Tuesday January 22nd, starting at 7:30 PM. Welcome to the reinvigorated Leaverite newsletter! Note that this is the same building as previous meetings. The room is near the elevators on the first floor in the same building as the Dietz Museum (now closed). Free parking in the Tyler street garage after 7 PM. There may be a class prior to us (until 7:15) so please wait for them to leave. First, I want to thank Steve Pegler for his service as president the last two years. It takes a large time commitment to juggle work and lead a volunteer group like ours. Steve organized a field trip committee and expanded into new collecting locations. The last two years were volatile due to our AMMM “home” being shut down but Steve worked through this with a friendly and comfortable style. He greatly expanded our mineral cleaning expertise with many experimental “witches brews”. Thank you Steve for all of the hard work! Our Guest Speaker: Mining and Exploration in Central Arizona by Nyal Niemuth, Arizona Geological Survey, Phoenix Branch Chief. The program will provide an over view of Arizona mineral resources and production featuring three major mines in Yavapai county. Additional special topics will include a quick review of possible new mining projects, why everyone is excited about potash and the Holbrook evaporate basin, and recent gold exploration/mining activity. Nyal Niemuth has been involved in mineral exploration in the southwest US since 1978, and worked over 30 years for the former Dept. of Mines and Mineral Resources as Mineral Resource Specialist and Mining Engineer. Since January 2011 he has served as the Arizona Geological Survey’s Phoenix Branch Manager. He became a registered geologist in Arizona in 1994 and serves on the Board of Technical Registration’s Enforcement Advisory committee for geologists. In 2010 Nyal received the Medal of Merit from the American Mining Hall of Fame. Secondly, thank you Mardy for being the “heart of the club” with your work as treasurer, outreach coordinator, raffle prize organizer, and fluorescence expert. Mardy has agreed to continue to lead these efforts in 2013. Thirdly, thanks to new volunteers who have stepped up to roles they haven’t done before. Stan has agreed to be VP, Casey & John will chair the field trip committee, Bob is our photographer, and Harvey is the club mineralogist. We added other explicit roles in order to distribute the load across more people and to make sure we have timely and diverse content for our newsletter and web site. Every volunteer organization is only as good as the people they attract and the energy level of the team. By being explicit on who is doing what, we can be more organized with a volunteer team. (President’s Message cont. on pg 2) January 2013 (President’s Message cont. from pg 1) Each month’s newsletter will provide details on upcoming field trips with meeting locations, mine site(s) history, photos of past material collected, and field trip leader contact info. We will describe what minerals/lapidary or material/fossils will be present and discuss their mineral properties. The following newsletter will include a trip report and photos. We will describe upcoming coalition trips and Arizona rock & mineral shows. We also need a few volunteers each month for a new feature - describe what aspects you enjoy in this hobby, your favorite rock, best trip, and what got you interested in rockhounding etc. This will help us create a stronger Leaverite community as we get to know each other a little bit more. In January’s meeting I will summarize the info you provided on interests in Steve’s survey. We want to make sure that we continue to hear the voices of our club members. There are still many Phoenix rock clubs, and we want to maintain our “niche”. Our club has been a magnet for folks who enjoy getting out in beautiful Arizona and finding minerals and lapidary materials. The other clubs in the Valley have limited field trips in comparison. Field trips are where club members get to know each other and form the bonds that make for friendships and good times. If possible we will add more time to our monthly meetings to socialize. We will still strive for quality programs where people learn new things about our hobby and hear exciting trip reports. Please send Stan or I your suggestions on speakers and also let us know if you want to present. One of the best ways that people get to know each other is to tell stories about their recent trips, lapidary work or cool specimens. We 2|Page want to hear tips on mineral cleaning, jewelry making, spheres, innovative rockhound tools, etc. Another change for our club is our enrollment into the Rocky Mountain Mineral Federation. You should soon start receiving their newsletter with a wealth of info and field trips. Club Officers & Chairs President: Dave Fanger, [email protected], (Board Member) 480-460-8290 Vice President: Stan Celestian, [email protected] (Board Member) Treasurer: Mardy Zimmermann,(Board Member) [email protected] 480-8396390 Previous President: Steve Pegler, [email protected] Secretary: Sue Parish (Board Member) Newsletter Editor: Deanna Smith, [email protected] Field Trip Coordinators: Casey Haderly [email protected] & John McLaughlin [email protected] Field Trip Team: Casey Haderly, Steve Baker, Tom Wistuber, John McLaughlin, Tim Messang, Steve Pegler, Myron Wagner, Coalition Rep: Tom Parks, [email protected] Leaverite Photographer: Bob Lagodny Leaverite Reporter: TBD Webmaster: TBD Club Historians: John McLaughlin, Pierre Cantou, Dick Zimmerman, Dave DeWeese Hospitality/Greeter/Membership: TBD Raffle: Mardy Zimmerman with help from TBD Leaverite Mineralogist: Harvey Jong Lapidary Experts: Doug Duffy, Tom Parks Fluorescent Expert: Mardy Zimmerman ASU Geology Student Rep Karen Rieck [email protected] ASU Geology Faculty Rep: Prof. Steven Semken [email protected] January 2013 This year’s Flagg show was the biggest and best ever. The show opened, as always, with the parade of elephants, each holding a Foundation flag with the Red Cloud wulfenite symbol on it. The clown car did not make the show this year as most of the participating Arizona legislators had not arrived in Phoenix yet. Mardy set a Flagg Show record by providing over 1,000 egg carton collections to the same number of happy kids and winter visitors from Iowa. Mardy noted that providing the record number of egg carton collections was possible due to the Leaverite members who volunteered their time. Dick had the helium tank and balloons for those people who were experiencing a helium deficiency. The publicity for the show included two or three articles in the Arizona Republic, TV interviews by several stations and of course the volunteer squadron of skywriting planes. This year the skywriting spelled out “Vanadinite For Sale” and was highlighted by two of the planes creating the crystal shape of vanadinite. The result was that every parking space at Mesa Community College was occupied by folks who rocked. The show featured new and used equipment, lots of lapidary rough, fine minerals, lousy minerals and meteorites, though no one was injured by the meteorites arrivals. For anyone who missed the show, it combines unusual minerals, rocks, egg cartons, funnel cakes, folks with colorful hair and lots of fun. 3|Page Most of the vendors I spoke with enjoyed a financially successful show. The space costs are low and the amount of space given the dealers by the Flagg Show Committee is most generous. Anyone wishing to get rid of old equipment, excess lapidary rough, duplicate specimens or annoying children can afford to participate. Your author and his wife are planning to take our earnings and purchase the island of Oahu. Pictures from the Flagg ShowThanks Bob! Leaverite Egg Carton Program Earth Science Museum’s Fluorescent Display January 2013 The Arizona Leaverites Rock & Gem Society, Inc., an Arizona 501(c)(3) taxexempt corporation, was formed in 2003 as a charitable foundation to facilitate volunteer activities and to provide a way for people and companies to make taxdeductible gifts to support earth science education in Arizona Since 2003, the Leaverites have provided over $35,000 worth of display cases, museum lighting, and CDs for Teacher Kits. Additionally, the Leaverites have sponsored a state-wide museum Outreach Program where volunteers provide support for mining and mineral educational enrichment programs for schools and clubs across the state. Our goal is to have fun with all our club activities! Many of our founding members have been active since the clubs' inception and there are many members that have considerable technical expertise in geology, lapidary and the jewelry arts. You can always count on learning something new at the meetings or on a field trip. Once again we had great weather for our Christmas Party. About 40 members and guests gathered for our “Best Ever Pot Luck” Christmas feast. This year we extended seating from the Zimmermann’s patio using the Earth Science Museum’s new tent. A highlight of the party was a Silent Auction, which replaces the one we had done in April in the past. The donations were excellent, and the club netted $436 which will be donated to the Earth Science Museum. The Flagg Show also enjoyed good weather for the entire weekend and turned out to be the most successful one yet. The Leaverites again sponsored the Egg Carton Program and we set a new record: 1,048 total. The $1048 raised is earmarked for the Earth Science Museum. Thanks to the tremendous support and help from Leaverites in helping me serve the many students and families: Lynne Wheeler, Cyndi Buckner, Jennifer and Randy Jordan, Georgia Zeutenhorst, Wally Frilch, Harvey Jong, and Dianne and Glen McFaul. Also much gratitude to all of the Leaverites who help by saving egg cartons and donate rocks, minerals, and fossils to the Egg Carton Program. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ The club used to provide considerable support for the Arizona Mining and Mineral Museum, but it was closed by the Arizona Historical Society. The Leaverites are now helping the new Earth Science Museum, as this museum is geared towards rock hounds and earth science education of children. 4|Page You can pay at the meeting, or Contact Mardy @ [email protected] 480-839-6390 January 2013 By Harvey Jong This article kicks off a new regular feature of the Arizona Leaverite newsletter. Each month we will focus on a specific mineral and provide the following information: Basic background and key identifying properties How the mineral forms along with common associations with other minerals Arizona localities and specimens Other notable occurrences The Mineral of the Month (MOTM) may involve minerals from recent or future field trips, new finds at gem and mineral shows, or your suggestions. With over 4800 minerals officially recognized as valid species by the International Mineralogical Association along with dozens of new mineral discoveries every year, there are plenty to choose from! This feature is not a super original idea, but hopefully we will have some fun learning a thing or two about minerals. To add some visual appeal, lots of photos and diagrams will be included, and members are encouraged to share images of interesting specimens in their collections for future articles. So, without further ado, let’s start the MOTM series with the mineral Chalcoite. If you went on the second Johnson Camp field trip, you may have collected a sample of a dark gray metallic mineral: Chalcocite with Malachite and Azurite Copper Chief mine, Johnson Camp, Cochise Co., AZ Size: 8 x 4 x 6 cm Harvey Jong specimen and photo This mineral has been identified as Chalcocite based on its black lead-gray streak and hardness of 2½ to 3. It has a monoclinic crystal structure; however, if it forms above 103 oC the mineral assumes a pseudohexagonal shape and is known as Djurleite. Chalcocite Crystal Drawing Courtesy of www.smorf.nl - CC BY-NC-SA 3.0 license Chalcocite crystals are relatively small and uncommon, tabular, often striated, and exhibit twinning. Twins have a hexagonal outline. Other identifying properties include metallic luster and conchoidal fracture. (Continued on page 6) 5|Page January 2013 Chalcocite is an important ore of copper and has been mined for centuries for its high copper content. Its chemical formula is Cu2S which indicates that the mineral is nearly 80% copper by weight. It is relatively easy to separate the copper from the sulfur, but Chalcocite is not abundant as other copper ore minerals. The name is derived from the Greek word, “chalkos”, for copper. Chalcocite can occur as a primary mineral (a mineral that forms at the same time as the host rock), but it is more typically a product of secondary enrichment. The enrichment process starts when surface water reacts with sulfide minerals, such as Pyrite, to form sulfuric acid. This acid leaches copper sulfides, such as Chalcopyrite, and the dissolved copper is carried downward by groundwater. The copper ions precipitate when they reach the water table and produce secondary copper minerals, such as Chalcocite, with higher copper content. A layer of Chalcocite forms around the water table level and is called a “Chalcocite blanket”. Arizona Localities and Specimens The 3rd edition of the Mineralogy of Arizona reports that Chalcocite is widely distributed in Arizona and lists over 50 localities. Here are a couple examples of Arizona specimens: Chalcocite Crystals Bisbee, Warren District, Cochise Co., AZ Field of view: 3.5 x 2.6 cm, largest crystal is ~3 mm Harvey Jong specimen and photo Secondary Enrichment Chalcocite can be found in association with Bornite, Calcite, Covellite, Cuprite, Chrysocolla, Enargite, Malachite, Pyrite, or Quartz.

High clearance will be necessary for last part of road so think about carpooling to get to the sitet. (See http://museum.wa.gov.au/research/collectio ns/earth-and-planetary-sciences/mineralcollection/chalcocite) I apologize for the late notice but hope you all can make it. Looking forward to seeing you out there. Next Mineral of the Month The theme of the upcoming Tucson Gem and Mineral Show is “Fluorite, Colors of the Rainbow”, so the next Mineral of the Month will be Fluorite.

Classes are held 11:30 – 3:30 on the 3rd Saturday of each month. Instructors Joanne Hesterman and Sandi McDonald have different styles. Joanne’s take on learning from different instructors, is that “the more people you learn from, the more it helps you develop your own style”. Joanne’s style (using half round wire) emphasizes the stone, so her wirework has less flourishes than Sandi’s (who uses round wire). John Rakovan Bring a straight edge 12” ruler, masking tape & a black sharpie. And of course paper & pen for notes. If you have wirework tools, bring them. Jesse Fisher Joanne is a retired high school teacher. She taught for 40 years at Central High & North High. She also volunteered at the AZMMM for many years Jesse Fisher Note: QDoba doesn’t charge Joanne/Sandi a fee or rent, so they ask that students buy lunch there as a way of giving back to QDoba.
