Indication of Gas-and Oil-seepags and Asphalt in Cambrian and Its Geologic Significance in Guizhou Province

本文在查阅前人大量资料的基础上，对贵州寒武系的油苗、气苗及沥青显示特征进行综述，并对油气生成、近聚、破坏、保存条件进行初步分析，指出其贵州寒武系的天然气远景区和可能远景区。

In this paper, there is an analysis of all the influences on formation, migration and accummulation, as well as preservation and escape of the oil-gas in Guizhou, according to the indication features of the gas- and oil-seepages and asphalt summarized from the early petroleum geologic work in this region.
