Clay mineral distribution from Bhimunipatnam to Pudimadaka along central eastern continental shelf of India

Forty-eight sediment samples, collected from 50-100 m depth on the east coast of India, were analysed for their clay mineral composition and distribution. Kaolinite with chlorite (K + C) is the predominant mineral followed by illite and montmorillonite. K + C and illite appear to originate from the...

Zusammenfassung:	Forty-eight sediment samples, collected from 50-100 m depth on the east coast of India, were analysed for their clay mineral composition and distribution. Kaolinite with chlorite (K + C) is the predominant mineral followed by illite and montmorillonite. K + C and illite appear to originate from the coastal red sediments and from the nearby Precambrian khondalites while montmorillonite is supplied by River Godavari from its drainage basin (Basaltic Deccan Traps) dispersed towards N by NE directed SW monsoon currents.
