Gypsum crystals in the inner shelf sediments off Maharashtra, India

Abstract

Gypsum crystals have been found in the inner shelf silty clay/clayey silt off the Maharashtra Coast between Vengurla and Bombay. Generally these occur as euhedral single or twinned crystals of selenite. Very often shells are found embedded within the crystals. The possible conditions of formation of the crystals are discussed and it is suggested that the crystals are non-evaporitic in origin
