Mineralogy and Mineral-chemistry of REE Minerals Occurring at Mountain Eorae, Chungju

Mineralogy of Asbestos Minerals

Over the past fifty years the mineralogy and crystal chemistry of the materials called asbestos have been refined leading to better identification through new and more sensitive techniques. The health aspects of the exposure to fibrous inorganic species are also equally well determined from the anatomical to the biochemical levels. Integrating the efforts of many researchers from a diversity of...

Chemistry and mineralogy of outcrops at Meridiani Planum

Analyses of outcrops created by the impact craters Endurance, Fram and Eagle reveal the broad lateral continuity of chemical sediments at the Meridiani Planum exploration site on Mars. Approximately ten mineralogical components are implied in these salt-rich silicic sediments, from measurements by instruments on the Opportunity rover. Compositional trends in an apparently intact vertical strati...

Experimental Mineralogy and Mineral Physics

Mineral chemistry of sulfide and sulfosalt minerals in the Cheshmeh-Noghreh barite (gold- silver) deposit, Sabzevar subzone, NE Kashmar

The Sebandoon Barite (gold-silver) deposit is located about 20 km NW of the Kashmar in the Central Iran. The rock units exposed in the area consist of Eocene volcano-sedimentary sequences of lithic tuff, rhyolitic tuff, tuffaceouce shale, lapilli tuff and agglomerate associated with pyroxene andesite and trachyandesite. The barite is composed of lenticular, banded and stockwork mineralization a...

The Mineralogy and Chemistry of Micrometeorites

Prior to their retrieval from low Earth orbit (LEO), the individual solar cells that make up the ‘-V2’ solar array panel from the Huhble Space Telescope (HST) were prone to hypervelocity (>5 k d s ) impact damage from micrometeoroids and space debris. The analysis of such passive collector surfaces allows sampling of micrometeoroids that have not undergone any terrestrial atmospheric alteration...
