闽西南聚煤盆地地质特征浅析

On the Characteristics of the coal accumulating basin in Southwest Fujian

闽西南聚煤盆地是在前泥盆纪变质基底之上发育起来的晚古生代残留盆地,二叠系童子岩组为其主要含煤层位。该盆地自形成后遭受多期次构造运动的强烈改造,形成现今复杂的构造格局。根据盆地的形成背景、沉积演化、后期改造及找煤方向等进行总结,并提出今后寻找隐伏煤矿方向。

In southwest Fujian coal accumulating basin is in the devonian metamorphic basedment on the development of late Paleozoic residual basin. The major coal-bearing bit exist in Per- mian tongziyan formation. Since the formation of the basin suffered many times strong re- construction of tectonic movement, the formation of today＇s complex tectonic framework. According to the formation background, sedimentary evolution, late refoumation and coal looking orientation of the basin, the author conclude and puts forward the future direction for concealed coal mine.
