摘　　要：选取煤与油页岩共生典型盆地山东黄县盆地、辽宁抚顺盆地、黑龙江依兰盆地和内蒙古金宝屯盆地,综合分析了其成矿物质特点,认为共生背景下煤岩中的低等动植物和油页岩中的高等植物均比单一矿种下含量高。这一规律可用于勘探、开发煤或油页岩单一矿种时预测其共生矿种存在的可能性。对古气候的分析表明,气候变换在一定程度上制约着煤与油页岩的共生模式,这种共生模式可为古气候研究提供一定依据,反之,通过古气候的变迁也可帮助勘探、开发共生背景下的煤与油页岩。Coals co-occur with oil shale in many basins of China. Generally, the proportion of lower animals and plants in coals is not prominently high in coal basins. Similarly, the proportion of higher plants in oil shale is often low in oil shale basins. Basing on data from 4 typical basins under co-occurring circumstances of coal and oil shale -Huangxian Basin from Shandong Province, Fushun Ba- sin from Liaoning Province, Yilan Basin from Heilongjiang Province and Jinbaotun Basin from Inner Mongolia Autonomous Region, analysis on metallogenic materials revealed that the proportions mentioned above were higher than in basins with single energy resourc- es, which may help in prospecting oil shale/coals when exploiting coals/oil shale. Paleoclimatic analysis on the 4 basins indicated that climatic transition influenced co-occurring modes to some extent. Therefore, co-occurring modes may act as an indicator in study on climatic transition, whereas, climatic transition may help to prospect co-occurring coals and oil shale.
