摘要

辽宁省凌源县龙潭沟元古界下马岭组底部有一层富含碳质沥青的砂岩。本文根据地化、地质资料论证了此层含沥青砂岩是一个在元古代晚期被辉长辉绿岩体破坏了的古油藏的遗迹。

Abstract

A lenticular sandstone with carbonized asphalt up to 8-15% is discoveredin the lowest part of the Upper Proterozoic Xiamaling Formation in Longtan-gou

Lingyuan County

west Liaoning. The authors consider that there was anoil pool in the Proterozoic which was then destroyed by the intrusive gabbro-diabase of 7.6340?0.0861 million years dated by K-Ar isotopic method

Inthe places where magmatism was weak

it is possible to find oil pools in the Proterozoic.
