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. -

Silver Oak Road, Salt Lake City, Utah 84108, U.S.A. ABST RA CT 6+ Thorneite, Pb6(Te2 O10)(CO3)Cl2(H2O), is a new tellurate from Otto Mountain near Baker, Califor- nia, named in honor of Brent Thorne. The new mineral occurs on fracture surfaces and in small vugs in brecciated quartz veins. Thorneite is directly associated with acanthite, cerussite, gold, hessite, iodargyrite, khinite, wulfenite, and three other new tellurates: housleyite, markcooperite, and ottoite. Various other secondary minerals occur in the veins, including three other new secondary tellurium minerals: paratimroseite, telluroperite, and timroseite. Thorneite is monoclinic, space group C2/c, a = 21.305(1), b = 11.059(1), c = 7.564(1) Å, β = 101.112(4)°, V = 1748.8(4) Å3, and Z = 4. Crystals are prismatic to bladed with elongation and striations parallel to c and typically occur in parallel and random aggregates. It is yellow and transparent, with pale yellow streak and adamantine luster. Mohs hardness is estimated at 2. The mineral is brittle, with an irregular to splintery fracture and good {100} cleavage. -

Silver Oak Road, Salt Lake City, UT 84108, USA [Received 6 March 2014; Accepted 5 May 2014; Associate Editor: G. D. Gatta] ABSTRACT 5+ 6+ Bluebellite, Cu6[I O3(OH)3](OH)7Cl and mojaveite, Cu6[Te O4(OH)2](OH)7Cl, are new secondary copper minerals from the Mojave Desert. The type locality for bluebellite is the D shaft, Blue Bell claims, near Baker, San Bernardino County, California, while cotype localities for mojaveite are the E pit at Blue Bell claims and also the Bird Nest drift, Otto Mountain, also near Baker. The two minerals are very similar in their properties. Bluebellite is associated particularly with murdochite, but also with calcite, fluorite, hemimorphite and rarely dioptase in a highly siliceous hornfels. It forms bright bluish- green plates or flakes up to ~20 mm 620 mm 65 mm in size that are usually curved. -
IMA–CNMNC Approved Mineral Symbols
Mineralogical Magazine (2021), 85, 291–320 doi:10.1180/mgm.2021.43 Article IMA–CNMNC approved mineral symbols Laurence N. Warr* Institute of Geography and Geology, University of Greifswald, 17487 Greifswald, Germany Abstract Several text symbol lists for common rock-forming minerals have been published over the last 40 years, but no internationally agreed standard has yet been established. This contribution presents the first International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) approved collection of 5744 mineral name abbreviations by combining four methods of nomenclature based on the Kretz symbol approach. The collection incorporates 991 previously defined abbreviations for mineral groups and species and presents a further 4753 new symbols that cover all currently listed IMA minerals. Adopting IMA– CNMNC approved symbols is considered a necessary step in standardising abbreviations by employing a system compatible with that used for symbolising the chemical elements. Keywords: nomenclature, mineral names, symbols, abbreviations, groups, species, elements, IMA, CNMNC (Received 28 November 2020; accepted 14 May 2021; Accepted Manuscript published online: 18 May 2021; Associate Editor: Anthony R Kampf) Introduction used collection proposed by Whitney and Evans (2010).

Pyromorphite Don Shurtz, Pleasant Oaks Gem and Mineral Club of Dallas
Member: South Central Federation of Mineral Societies Affiliated: American Federation of st October 2020 1 Place, 2019 SCFMS Mini-Bulletin Mineralogical Societies . st Vol. 54, Issue 10 1 Place, 2017 AFMS Mini-Bulletin Pyromorphite Don Shurtz, Pleasant Oaks Gem and Mineral Club of Dallas Pyromorphite has been a side topic in different Chips and Chatter articles, but never the main topic. Amongst mineral collectors, pyromorphite is a popular mineral. Pyromorphite is lead chlorophosphate, Pb5(PO4)3Cl and is part of a series with Mimetite, Pb5(AsO4)3Cl and Vanadinite, Pb5(VO4)3Cl; note the similar chemical formula. Pyromorphite has a Mohs hardness of 3.5 to 4.0 and a white streak. The pyromorphite comes in a variety of colors including green, yellow, reddish orange, brown, tan, white, and even clear. The brighter color specimens (green, yellow, and orange) seem to be most popular with collectors. One aspect of the crystals of pyromorphite is that they can be hollow. Interestingly, all the members of the pyromorphite, vanadinite, and mimetite series can have cavernous (hollow) needles. In the February 2020 Chips and Chatter article on Crocoite, I mentioned that it was my understanding, without any references to back it up, that only four minerals had hollow crystals. In that article, I mention crocoite, pyromorphite, and vanadinite. Now I can add mimetite to complete that list. All four are lead based minerals! The only other mineral that I have seen with hollow needles was a plumbogummite replacement of a crocoite specimen; the original mineral shape was hollow and was not altered in the replacement by plumbogummite. -

The geochemistry of antimony and its use as an indicator element in geochemical prospecting. J. Geochem. Explor., 20: 223-302. The geochemistry of antimony is reviewed, and the use of the element as an indicator in geochemical prospeoting for various types of mineral deposits is outlined. Antimony is widely diffused in many types of mineral deposits, particularly those containing sulphides and sulphosalts. In these and other deposits, antimony commonly accompanies Cu, Ag, Au, Zn, Cd, Hg, Ba, U, Sn, Pb, P, As, Bi, S, Se, Te, Nb, Ta, Mo, W, Fe, Ni, Co , and Pt metals. Under most conditions antimony is a suitable indicator of deposits of these elements, being particularly useful in geochemical surveys utilizing primary halos in rocks, and secondary halos and trains in soils and glacial materials, stream and lake sediments, natural waters, and to a limited degree vegetation. -

Diego Gatta] ABSTRACT 2+ 6+ Andychristyite, PbCu Te O5(H2O), is a new tellurate mineral from Otto Mountain near Baker, California, USA. It occurs in vugs in quartz in association with timroseite. It is interpreted as having formed from the partial oxidation of primary sulfides and tellurides during or following brecciation of quartz veins. Andychristyite is triclinic, space group P1, with unit-cell dimensions a = 5.322(3), b = 7.098(4), c = 7.511 (4) Å, α = 83.486(7), β = 76.279(5), γ = 70.742(5)°, V = 260.0(2) Å3 and Z = 2. It forms as small tabular crystals up to ∼50 µm across, in sub-parallel aggregates. The colour is bluish green and the streak is very pale bluish green. Crystals are transparent with adamantine lustre. The Mohs hardness is estimated at between 2 and 3. -
