chamosite การใช้

• Clinoclore, pennantite, and chamosite are the most common varieties.
• Chamosite may be found in occurrence with other chlorite minerals.
• Chamosite may be greenish gray or brown in color.
• Chamosite is a mineral from which elements may be extracted for commercial purpose.
• Greenalite occurs with quartz, stilpnomelane, siderite, chamosite, pyrite and minnesotaite.
• Chamosite is a relatively uncommon mineral in nature.
• In 1820, Pierre Bertier; a mineralogist and mining engineer from Nemours, France, discovered chamosite.
• Chamosite is named after the municipality of Chamoson, between Sion and Martigny, the canton of Valais, Switzerland.
• In 1919, Smyth showed that a green mineral in the Clinton ores was chamosite and also a primary sediment.
• Early chamosite ( which are chlorites ) stirred some controversy after they discovered to have possessed the structure of kaolin rather than chlorite.
• The south is mainly Torridonian sandstone and shale; the north is grey-banded chamosite ores which were worked commercially in the early 20th century.
• Chamosite has a laminar shape, sheets measure from 20 to 200 ?m ( M . L . Rivas Sanchez et al ., 2006 ).
• In recent years, berthierine; a more abundant chlorite, was discovered in occurrence with chamosite in the iron deposit of Pena Colorada, Mexico.
• Formation of chamosite bearing oolites record periods of increasing wave energy corresponding to storm conditions between quiet shallow marine sedimentation, ( Akande and Mucke, 1993 ).
• But further research proved that chamosite was largely in existence with another phyllosilicate called berthierine ( which has a kaolin type structure ) which was rather difficult to distinguish from chamosites.

• The chamosite structure is very similar to typical chlorite in which they are alternated regular layers with tetrahedral and tri-octahedral components ( M . L . Rivas Sanchez et al ., 2006 ).
• Dai, S . et al . ( 2008 ) conducted a mineralogical and geochemical study of coal from two coal mines in this region, and identified chamosite as one of the main minerals in the coal.
• Chamosite is related to the beginning of a hydrothermal phase and occurs mainly in a mineralized breccia type stock-work in which it fills open spaces and replaces the hot rock through fissures ( M . L . Rivas Sanchez et al ., 2006 ).
• The chamosite spectra shows the reflection d = 7.18 ?( main value of the chlorite ) and the reflection d = 14.4 ?( that confirms the presence of chlorite ) ( M . L . Rivas Sanchez et al ., 2006 ).
