Abstract

Upper Cretaceous organic-rich carbonates in Israel contain benthonic foraminifera and varying amounts of early diagenetic infilling of sparry calcite. Relates to light oxygen compositions of the diagenetic calcite to depletion of 18 O in pore water of normal salinity, a direct consequence of organic matter decomposition in the sulfate-reducing zone. -from Authors
