Now the pile is gone. While digging and some careful looking can still net you a piece of the pink, it is not as easy as it once was to find a quality piece of rhodonite. Our old friend, Bill Wardle, used to say that he could go out to the Fraser River bars and pick up five jade slicks. Now most of us are lucky to find one in a lifetime. When I started rockhounding in 1996, we used to see all kinds of sillimanite, and usually kicked the pieces aside. Now, even those are hard to find. So you can see that it is important not to deplete the supply of interesting rocks and minerals from the locations we have already found, and to leave some behind for others. It is also important to continue searching for new sites for future Rockhound trips. Here in B.C., we have our minerals hidden under several feet of overburden, and it requires lots of looking, digging, and a keen, Past president Walt Pinder, passing the observant eye to notice the small bits on the gavel to incoming president De Morgan surface that indicate the bonanza below..

Experiments especially by Fourier transformed infrared spectroscopy, were applied to a wide range of samples with controlled origin. The methods were optimised and resulted in premises to apply the techniques to analysis of the archaeological material.

Euskaltzaindiak erabaki du Euskaltzaindiaren Hiztegiaren uneko bertsioan sartu ez diren baina bi alderdi hauetatik begiratuta sartu behar liratekeen hitzak biltzea eta gizarteratzea: • Hezkuntzan irakasten den kontzeptua izatea: Bigarren Hezkuntza, Batxilergoa eta Unibertsitateko lehen mailak. • Zientzia eta teknologiaren dibulgazioan (komunikabideetan, liburuetan. ) erabilia izatea. Horretarako, arloka egiten da lan, eta, arlo bakoitzean, ZTHB lantaldeak arloko adituz osatutako berariazko talde baten laguntza du. Arloko testuetako tradizioa eta erabilera aztertu ondoren, eta Eus- kaltzaindiaren lexikorako irizpide orokorrak kontuan izanik, lantaldeak arloko oinarrizko kontzeptuetarako euskarazko adierazleak proposatzen dizkio Euskaltzaindiari.

    Nbsnadq1/0/Lhmdq`knhcnesgdLnmsg9Narhch`m+ u `qhdsx @ o `bgdS d`qr This month we are featuring the mineraloid obsidian from a classic source in Arizona. Our write-up explains obsidian’s unusual volcanic origin, why it is not classified as a mineral, why its flaked edges are sharper than even those of surgical scalpels, the legend behind the name “Apache tears,” and much more. We invite you to enjoy this fascinating information! OVERVIEW PHYSICAL PROPERTIES Chemistry: Obsidian, which is not classified as a mineral, is a natural volcanic glass consisting of an indeterminate, noncrystalline mixture of silica with lesser amounts of feldspar minerals and ferromagnesian minerals. Class: Mineraloids Crystal System and Habits: None (amorphous) Color: Usually black, greenish-black, or smoky; also gray, reddish-brown, mahogany, and dark green; occasionally yellow, golden, or iridescent. Mixed colors can produce a mottled or banded appearance. Luster: Vitreous on fresh surfaces Transparency: Translucent; sometimes subtransparent along thin edges; thick pieces or nodules (Apache tears) can appear opaque. Streak: White Refractive Index: 1.48-1.51 Cleavage: None Fracture: Conchoidal Hardness: 6.0-7.0 Specific Gravity: 2.3-2.6 Luminescence: None Distinctive Features and Tests: Best field marks are occurrence in volcanic environments, especially rhyolitic lava flows or perlite (altered obsidian) formations; vitreous luster; and color banding. Sometimes confused with smoky quartz [silicon dioxide, SiO2]. Dana Classification Number: None NAME The name obsidian, pronounced Obb-SIH-dee-un, derives from the Latin obsianus lapis, literally “stone of Obsius,” after a Roman explorer who discovered an obsidian deposit in Ethiopia. Obsidian is also known as “lava glass,” “black lava glass,” “volcanic glass,” “mahogany glass,” “Bergmahogany,” and “xaga.” The term “Apache tears” refers to rounded obsidian nodules.

  • Mineral of the Month Club June 2017
    Mineral of the Month Club June 2017 OPAL subvar. FIRE This month our featured mineral is the fire subvariety of common opal from Mexico. Our write- up discusses the mineralogy of fire opal, the origin of its yellow-orange-red coloration, and its classification as a mineraloid. OVERVIEW PHYSICAL PROPERTIES Chemistry: SiO2·nH20 Hydrous Silicon Dioxide, containing varying amounts of water. The fire subvariety of common opal contains traces of hematite and hydrous iron oxides. Class: Silicates Subclass: Tectosilicates (Framework Silicates) Group: Hydrated Tectosilicates Subgroup: Opal Crystal System: None; opal has a noncrystalline structure. Crystal Habits: None; occurs as amorphous fillings or botryoidal coatings in vugs and fissures. Color: Fire opal is always a shade of yellow, orange, or red, or a mix of these colors; color intensity varies from pale to saturated; color zoning and multicoloration is common. Fire opal occasionally exhibits an internal play of green color. Luster: Vitreous to dull Transparency: Transparent to translucent Streak: White Cleavage: None Fracture/Tenacity: Conchoidal; tough. Brittleness increases with level of hydration. Hardness: 5.5-6.0 Specific Gravity: Varies with water content from 1.9 to 2.3; the average specific gravity of all opal varieties is 2.09. The specific gravity of fire opal is about 2.2. Luminescence: Most opal fluoresces pale greenish-yellow in shortwave ultraviolet light and white in long-wave ultraviolet light. Refractive Index: 1.44-1.46 Distinctive Features and Tests: The best field identification marks for fire opal are low density; conchoidal fracture; lack of crystal faces and cleavage planes; yellow- orange-red coloration; and occurrence in rhyolite formations.

  • A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates by Keith R. Long Open-File Report 91-0579 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 1991 Preface In recent years, almost all countries in Latin America have adopted democratic political systems and liberal economic policies. The resulting favorable investment climate has spurred a new wave of North American investment in Latin American mineral resources and has improved cooperation between geoscience organizations on both continents. The U.S. Geological Survey (USGS) has responded to the new situation through cooperative mineral resource investigations with a number of countries in Latin America. These activities are now being coordinated by the USGS's Center for Inter-American Mineral Resource Investigations (CIMRI), recently established in Tucson, Arizona. In the course of CIMRI's work, we have found a need for a compilation of Spanish geological and mining terminology that goes beyond the few Spanish-English geological dictionaries available. Even geologists who are fluent in Spanish often encounter local terminology oijerga that is unfamiliar. These terms, which have grown out of five centuries of mining tradition in Latin America, and frequently draw on native languages, usually cannot be found in standard dictionaries. There are, of course, many geological terms which can be recognized even by geologists who speak little or no Spanish.

  • New Mexico Bureau of Geology and Mineral Resources Rockhound Guide
    New Mexico Bureau of Geology and Mineral Resources Socorro, New Mexico Information: 505-835-5420 Publications: 505-83-5490 FAX: 505-835-6333 A Division of New Mexico Institute of Mining and Technology Dear “Rockhound” Thank you for your interest in mineral collecting in New Mexico. The New Mexico Bureau of Geology and Mineral Resources has put together this packet of material (we call it our “Rockhound Guide”) that we hope will be useful to you. This information is designed to direct people to localities where they may collect specimens and also to give them some brief information about the area. These sites have been chosen because they may be reached by passenger car. We hope the information included here will lead to many enjoyable hours of collecting minerals in the “Land of Enchantment.” Enjoy your excursion, but please follow these basic rules: Take only what you need for your own collection, leave what you can’t use. Keep New Mexico beautiful. If you pack it in, pack it out. Respect the rights of landowners and lessees. Make sure you have permission to collect on private land, including mines. Be extremely careful around old mines, especially mine shafts. Respect the desert climate. Carry plenty of water for yourself and your vehicle. Be aware of flash-flooding hazards. The New Mexico Bureau of Geology and Mineral Resources has a whole series of publications to assist in the exploration for mineral resources in New Mexico. These publications are reasonably priced at about the cost of printing. New Mexico State Bureau of Geology and Mineral Resources Bulletin 87, “Mineral and Water Resources of New Mexico,” describes the important mineral deposits of all types, as presently known in the state.
