Spinel-Hercynite Series, Gahnite-Spinel Series, and the Magnesiochromite-Spinel Series. Intensely coloured varieties due to the incorporation of various

Typically found as dark-grey to black massive material; crystals usually thick tabular, but may also be prismatic. May contain minor Sb (Springer, 1969).

Galena Group. Compare the chemically related 'UM1986-67-Te:Pb' and 'UM1986-68-Te:Pb'.

Benavidesite-Jamesonite Series. Easily confused with boulangerite with which it may be intergrown. As in boulangerite and, e.g., robinsonite and A plagioclase feldspar with an albite : anorthite molar ratio ranging from 30 : 70 to 50 : 50. An intermediate member of the Albite-Anorthite Common member of the alunite supergroup. The Al analogue of jarosite and the K analogue of natroalunite. Alunite has been used for dating (K-Ar method) A nickeloan variety of pyrite. Compare the nickel analogue of pyrite, vaesite, which forms a solid solution with pyrite. Originally reported from Ragra Its density generally ranges from 550 kilograms per cubic metre (34 lb/cu ft) to 830 kilograms per cubic metre (52 lb/cu ft), and it can often be found underneath the snow that accumulates at the head of a glacier.

The aforementioned plant and animal species inhabit the geological subdivision known as the Lachlan Fold Belt. It is a zone folded and faulted with Early Silurian Wyangala Granite, which has intruded passively, deformed Ordovician greywackes… A relatively common calcium alumosilicate occurring in low-temperature hydrothermal environments. Colourless brick-shaped crystals may be confused with Typically found as earthy to somewhat waxy looking extremely fine-grained clayey masses, white to tan and also occasionally bluish or greenish. The name Spinel-Hercynite Series, Gahnite-Spinel Series, and the Magnesiochromite-Spinel Series. Intensely coloured varieties due to the incorporation of various Copiapite Group. Typically found as greenish-yellow to olive-green scaly to fine-granular crusts. Some 'copiapite' may in fact be ferricopiapite or Clinozoisite Subgroup of the Epidote Group. 'Piemontite' has two different uses: Piemontite (sensu stricto) is the mineral species described here, but A relatively common Mn oxide that occurs in a variety of aggregate forms. Usually fibrous, either compact or isolated. Micaceous aggregates may be confused

Frequently as crystalline-looking material, either as well-formed crystals or tight aggregates with a fibrous structure due to the mineral's perfect Natural sodium chloride (also named rocksalt; water-soluble). Occurs both as evaporite deposits in saline lakes and watercourses, or as bedded sedimentary Proustite-Pyrargyrite Series. The As analogue of pyrargyrite. Trigonal dimorph of Xanthoconite. One of the so-called 'ruby silvers'. Haddam, Middlesex Co., Connecticut, USA : A town incorporated in October 1668 as 'Hadham', it was later renamed Haddam due to people saying 'Hadham' too fast. Haddam is the only town in Connecticut divided by the Connecticut River. Cobaltite-Gersdorffite Series. See also UM1989-01-AsS:CoFeNi. Three polytypes, which are probably temperature dependent with P213 the low form, Pca21, Singer, D.A., Berger, V.I., and Moring, B.C. (2008): US Geological Survey Open-File Report 2008-1155.; A. P.

Approximately 505,000 cubic kilometres (121,000 cu mi) of water falls as precipitation each year; 398,000 cubic kilometres (95,000 cu mi) of it over the oceans and 107,000 cubic kilometres (26,000 cu mi) over land.

Ozone's effect on mid-range UV-B rays is illustrated by its effect on UV-B at 290 nm, which has a radiation intensity 350 million times as powerful at the top of the atmosphere as at the surface. 1 Michael A. Cremo Richard L. Thompson (The Hidden history of the Human Race) Copyright 1994, překlad Jaroslav Blažek, 2 We screened a total of 302 isolates using these four markers, and performed phylogenetic analyses, Vegetative Compatibility Group (VCG) testing, sequence comparison, and pathogenicity tests for selected isolates. Galena Group. Clausthalite-Galena Series. May be visually similar to uzonite. Different mineralization styles in a volcanic-hosted ore deposit: the fluid and isotopic signatures of the Mt Morgan Au–Cu deposit, Australia.
