| 摘 要： | 近年来，福建煤田地质局在龙岩吕凤、永春县含春北矿区上侏罗统岩浆岩下找煤工作取得了新的突破，对缺煤的福建省来说具有重要意义。从聚煤环境和区域构造背景分析来看，岩浆岩盖层分布区属二叠纪聚煤盆地重要成煤区域，且岩浆岩常超覆在晚古生代地层之上。通过分析上侏罗统岩浆岩的岩性特征和物性特征，认为岩浆岩覆盖层与其下伏煤系地层之间明显的物性差异是找煤的主要依据。以吕凤煤矿区、含春北勘查区成功找煤实例为基础．提出了侏罗系长林组和南园组盖层下找煤的六个远景区。

| Abstract: | In recent years, the Fujian Bureau of Coal Geological Exploration＇s new breakthrough has been achieved on coal looking under the Upper Jurassic volcanic rocks in Lufeng of Longyan City, Hanchun north mine of Yongchun County, that is important for the coal short Fujian Province. From analysis of coal-accumulating environment and tectonic setting, the volcanic rock covered area belongs to an important coal-forming Permian coal-accumulating basin, then again volcanic rocks are often overlapped on Late Paleozoic strata. After analyzed volcanic rock lithological and physical characteristics, considered that the obvious physical property differentia between volcanic overburden and underlying coal measures strata is the basis of coal looking. Based on successful coal looking in Lufeng eoalmine and Hanchun north exploration areas put forward 6 coaX looking prospect areas under the Jurassic Changlin Formation and Nanyuan Formation overburdens. |
