Geochemistry of the kaolin deposits of Swat (Pakistan

2008-6-25  The Swat deposits are amongst the oldest known kaolin (China clay) deposits of Pakistan. The deposits lie in the low hilly terrain in the eastern vicinity of Shah Dheri village (GPS: 34°53′30″N; 72°14′02″E), situated 20 km NNW of the Mingora city in Swat District ().Previous work on these deposits included their economic evaluation, exploration and industrial utilization studies by

Kaolin deposits of the Swat District in Pakistan are indicated to have derived by hydrothermal alteration of more feldspathic parts of felsic intrusives, which occur enclosed in orthoamphibolites and orthogneisses of the Cretaceous Kohistan Island Arc terrane. These latter “country rocks” formed under epidote–amphibolite conditions that prograde northwards to amphibolite facies, and

INTRODUCTION The Swat kaolin deposits lie in the low hilly terrain in the eastern vicinity of Shah Dheri village (GPS: 34° 53′ 30″ N; 72° 14′ 02″ E), situated 20 km NW of Mingora city, Swat District, SW Himalayas, Pakistan (Figure 1a). These deposits are amongst the oldest known kaolin deposits of Pakistan.

PHASE AND MICROSTRUCTURAL CHARACTERIZATION

2015-6-15  Berbuff, Nargus and Durr clay samples, commonly known as various grades of Swat china clay, were characterized and compared with imported English china clay. Dehydration of these clays occurred at ~90 to 150ºC, followed by dehydroxylation at ~500 to 530ºC. The formation of γ-Al 2O3-type spinel phase or primary mullite began at ~990 to

Sediment-Hosted Kaolin Deposit from Çakmaktepe (Uşak

2015-8-1  Because of their geochemical properties, the Çakmaktepe (Uşak) kaolin deposits have been considered as primary. New sedimentological, mineralogical, and geochemical data suggest that the Çakmaktepe kaolins are secondary deposits of sedimentary processes after hydrothermal alteration of the source rocks. The kaolins in the Çakmaktepe deposit were formed from the hydrothermal alteration of

Kaolins: their properties and uses Philosophical

The main commercially important kaolin resources are the primary deposits in Cornwall and the sedimentary deposits in South Carolina and Georgia in the U.S.A. Annual world production is about 18 Mt (1 t = 10 3 kg). In 1981 the U.K. production was 2.6 x 10 6 t of which about 77 % represented paper filler and paper coating grades. About 15% of the U.K. production is used in ceramics.
