摘要
大田含煤盆地的上京永丰、建设大竹林等井田发现童子岩组底部存在含花岗岩、变质岩、石灰岩、砂岩、泥岩等多种砾石的砾岩层。对该砾岩层的深入研究,不仅对本省童子岩组与文笔山组的划分及童子岩期聚煤岩相古地理的研究具有重要的意义,而且对本省花岗岩时代的确定、花岗岩分布、成矿规律以及本省地质构造等方面的研究均有重大的意义。
The basal conglomerate bed was found in the base of Tongziyan Formation (P_1t) from some areas of Datian coal-bearing basin, which contains graveles of granite, metamorphic rocks, limestone, sandstone and mudstone. Study of the basal conglomerate bed is of great importance not only to the division of Tongziyan Formation from Wenbishan Formation of Fujian Province and the lithofacies-palaeogeographic study of Tongziyan coal-forming stage, but also to the study of granite distribution, age of granite, minerogenic conditions and geological structures of Fujian Province.
