Abstract
The geology of the Capim region in Brazil is composed of Ipixua Formation in Mesozoic-Tertiary(Miocene), sedimentary rocks in Miocene, Barreiras Formation(sedimentary rocks) in Pleistocene and sediments in Holocene. Kaolin deposit consists of Barreiras Formation(average depth in 120m) composed of sandstone, clay, fine sand of Miocene to Pliocene age. Kaolin of the high grade is white in color and its thickness averages 7m. The orebody formed by kaolinite was confirmed by XRD, is shape of hexagonal, SK is above 33 degree. It is class A also suit for producing a paper without filtration. According to the CPRM report, the reservation of kaolin ore is amounts of 566,819,164 tons.
