Gypsolyte Sedimentary Environment of Upper Jurassic-Lower Cretaceous in Shenglihe Area in Northern Qiangtang Basin

Abstract

Abstract: In 2007, a set of gypsolyte strata with depth of 196 m was found above Suowa formation of Upper Jurassic in Shenglihe area in northern Qiangtang basin of Tibet. This study suggests from analyses of top-bottom lithology and gyprock crystal forms, interbed and sedimentary assemblage that such strata are characterized by coast salt lake deposit. Its discovery could provide good cap rock for hydrocarbon accumulation in the Mesozoic northern Qiangtang basin.

Key words: Tibet, North Qiangtang, Shenglihe formation, gypsum, gyprock, coast salt lake
