摘要
五亩盆地是灵宝盆地边缘的一个次级盆地,长期以来学者对其含煤性均未明确答复,对其煤类及煤质特征亦未进行专项研究。本文通过分析该盆地沉积环境和沉积特征,对该盆地穿时地质体项城组所赋存的劣质长焰煤的演化过程、聚煤作用进行了较为深入的研究,指出该盆地沉降中心与富煤带空间位置上存在差异,分析了项城组劣质煤属于异地煤的可能性,并进一步印证了古近纪全球性干旱气候带的客观存在。
It has been an open question for a long time that whether Wumu basin, a secondary basin on the edge of Lingbao basin, cotain coal.And there is not answer that the kind of coal and the coal quality characteristic. In this paper, we analyzes the basin sedimentary environment and sedimentary characteristics, and carried on the thorough research for the diachroneity geologic body Xiangcheng Formation by the processes of the occurrence of inferior long-flame coal and coal accumulating effect.We point out that a difference exists between the basin subsidence center and rich coal belt space position, and the possibility that the inferior coal of Xiangcheng Formation may belong to allochthonous coal. Furthermore, the objective existence of the global drought climate zone in paleogene is identified.
