Tonghua Basin��as a fault basin overlying the pre-Mesozoic basement��experienced the Hercynian movement in the Late Paleozoic and Yanshan movement in the late Middle Jurassic��has been a explorated in lower degree�� Research of the petroleum geological conditions indicates that during the basin evolution��the Yingzuilizi-�� Xiahuapidianzi-and Hengtongshan Formations��formed in the sedimentary stages after Early Cretaceous volcanism�� are the main hydrocarbon source rocks in the Tonghua Basin�� The Sankeyushu Depression and Sanyuanpu Depression�� are better in source rock condition��in which the source-reservoir-cap rock assemblage was found��and can be regarded as the key area for further exporation�� By utilizing pyrolysis method��it is calculated that in the favorable distribution of source rocks in the Tonghua Basin��the quantity of hydrocarbon generation is 3. 87 × 108 t and the quantity of resource is 0. 302 × 108 t��which shows a good petroleum potential��
