Download PDF About Minerals Sorted by Mineral Name
MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky. -

Views with Smallholder Farmers in Ecuador’S Mazar Watershed Were Combined with Secondary Sources
EL ARADO: BREAKING GROUND FOR PAYMENT FOR ENVIRONMENTAL SERVICES BASED ON OPPORTUNITY COSTS OF CONSERVATION IN ECUADOR A thesis presented to the faculty of the Center for International Studies of Ohio University In partial fulfillment of the requirements for the degree Master of Arts Chela Kirpal Moore June 2004 This thesis entitled EL ARADO: BREAKING GROUND FOR PAYMENT FOR ENVIRONMENTAL SERVICES BASED ON OPPORTUNITY COSTS OF CONSERVATION IN ECUADOR BY CHELA KIRPAL MOORE has been approved for the Center for International Studies by Brad Jokisch Director, Latin American Studies Josep Rota Director, Center for International Studies MOORE, CHELA KIRPAL. M.A. June 2004. International Development Studies El Arado: Breaking Ground for Payment for Environmental Services Based on Opportunity Costs of Conservation in Ecuador (117pp.) Director of Thesis: Brad Jokisch Payment for Environmental Services is a market mechanism designed to achieve sustainable development, with beneficiaries of environmental services paying landholders whose resources provide those services. This thesis explores how opportunity costs of conservation can be a tool for designing effective payments. Interviews with smallholder farmers in Ecuador’s Mazar Watershed were combined with secondary sources. The value of production per hectare per year, a proxy for farmers’ opportunity costs, was calculated for three land uses: potato and corn cultivation, and dairy. The thesis demonstrates: 1. dairy farming’s value of production is declining and does not constitute the highest return; 2. there are poor conditions for potato cultivation, generating a low value of production; 3. corn cultivation results in the highest value of production. Therefore, two scenarios for designing payments per hectare per year are suggested: the highest value of production, $239.13, and the value from a production mosaic, $190.40. -

Source to Surface Model of Monogenetic Volcanism: a Critical Review

SMITH1 &K.NE´ METH2* 1School of Environment, University of Auckland, Auckland, New Zealand 2Volcanic Risk Solutions, Massey University, Palmerston North 4442, New Zealand *Correspondence: [email protected] Abstract: Small-scale volcanic systems are the most widespread type of volcanism on Earth and occur in all of the main tectonic settings. Most commonly, these systems erupt basaltic magmas within a wide compositional range from strongly silica undersaturated to saturated and oversatu- rated; less commonly, the spectrum includes more siliceous compositions. Small-scale volcanic systems are commonly monogenetic in the sense that they are represented at the Earth’s surface by fields of small volcanoes, each the product of a temporally restricted eruption of a composition- ally distinct batch of magma, and this is in contrast to polygenetic systems characterized by rela- tively large edifices built by multiple eruptions over longer periods of time involving magmas with diverse origins. Eruption styles of small-scale volcanoes range from pyroclastic to effusive, and are strongly controlled by the relative influence of the characteristics of the magmatic system and the surface environment.

This article is published with open access Abstract Hadal trench bottom (>6000 m below sea level) sediments harbor higher microbial cell abundance compared with adjacent abyssal plain sediments. This is supported by the accumulation of sedimentary organic matter (OM), facilitated by trench topography. However, the distribution of benthic microbes in different trench systems has not been well explored yet. Here, we carried out small subunit ribosomal RNA gene tag sequencing for 92 sediment subsamples of seven abyssal and seven hadal sediment cores collected from three trench regions in the northwest Pacific Ocean: the Japan, Izu-Ogasawara, and fi 1234567890();,: 1234567890();,: Mariana Trenches. Tag-sequencing analyses showed speci c distribution patterns of several phyla associated with oxygen and nitrate. The community structure was distinct between abyssal and hadal sediments, following geographic locations and factors represented by sediment depth. Co-occurrence network revealed six potential prokaryotic consortia that covaried across regions. Our results further support that the OM cycle is driven by hadal currents and/or rapid burial shapes microbial community structures at trench bottom sites, in addition to vertical deposition from the surface ocean. -
