16.01.2020 Kaolin mineral is a common clay mineral in the natural world It is a useful mineral for white pigment therefore whiteness is an important index influencing the value of kaolin mineral There are iron organic matter dark material and other impurities in kaolin mineral These impurities will make kaolin mineral appearing in different colors
Modern occurrences of hydrothermal barite are known only from the oceanic setting which can be either a mid ocean ridge or a back arc spreading center whereas most ancient lead zinc barium deposits belong to the continental category Modern rift related deposits of Pb and Zn occur on many mid ocean ridges either bare ridges or those with significant sediment cover In the latter category

Stratabound Zn Pb Cu barite mineralisation is common in the Upper Permian and Triassic of the Jameson Land Basin of East Greenland It remains ambiguous whether this mineralisation is exhalative diagenetic or related to later Palaeogene events as seems to be the case for the sandstone hosted veins of the nearby Blyklippen deposit from which 550 000 t at 9 Pb and 10 Zn were mined between
