Kaolin and halloysite deposits of Brazil - GeoScienceWorld
2006-9-1 The kaolin industry in Brazil has shown a dramatic rise over the last 15 years with production of beneficiated kaolin increasing from 0.66 Mt in 1990 to 2.5 Mt in 2005. The reason for the growth is solely the development of large kaolin deposits in the Amazon Basin that account for 90% of Brazil’s production.

On the origin of the name kaolin and the kaolin deposits
1997-6-1 Most of the halloysite is present as long filaments with a uniform occurrence and is found on both the exposed (001) surfaces and edges of muscovite. In contrast, a small amount of the halloysite-like mineral occurs as stumpy, sheet stacking, which has an irregular appearance and occurs mainly at the margins of the muscovite plates.
