Source rocks in Cuu long basin of vietnam’s continental shelf
Abstract
The aim of this work is to describe the source rocks in Cuu long Basin mainly consisting Cenozoic sediments (lower Oligocene + upper Eocene, upper Oligocene and lower Miocene) that are poor to rich in organic matter. The organic carbon (TOC%) in lower Oligocene + upper Eocene source rocks contains mostly kerogen type II, sometimes type I, III is 1.19-2.87%; in upper Oligocene source rocks containing mostly kerogen type II, sometimes type I and III is 1.14-4.0%; and in lower Miocene source rocks contains mostly kerogen type III is 0.64-1.32%. The Oligocene sediments are mostly deposited in lagoonal, estuarial and mixed environment. The depostitional environment of the organic matter in the lower Miocene sediments is terrestry.
