| 中文摘要: |
| 闽西南坳陷带矿产资源丰富,是福建省铁、铜、金、煤、石灰岩等金属、非金属矿产的重要产地.永定樟坑-张岩下位于该带的西南部,通过对该区的地质、地球物理等方面的工作,对已发现的主要矿体进行系统的研究,发现了新的矿产地.文章论述了樟坑-张岩下铜多金属矿床的地质与地球物理特征,初步认为是复成因层控型矿床,是由于石炭系与早二叠系碳酸盐岩地层受到中、中酸性岩浆侵入而发生较大规模的夕卡岩化,成矿热液沿断裂面和层间滑脱构造面进一步对碳酸盐岩进行改造、交代而成. |
| 英文摘要: |
| The southwest Fujian depression belt is rich in mineral resources, and is an important locality of metal and nonmetal resources such as iron, copper, gold, coal, limestone, etc. Zhangkeng- Zhangyanxia area of Yongding County is in the southwest part of this belt. By systematical geological and geophysical works on the existed main orebody, new ore fields have been found. Geological and geophysical characters in Zhangkeng -Zhangyanxia copper - polymetal deposit is discussed and the deposit is considered preliminarily as a multi - genesis stratabound type. The deposit is formed by a large - scale skarnization due to the igneous magma intruded into the Carboniferous and early Permian carbonate rock, and replaced by hydrothermal oreforming fluids along faults and decollement layer in carbonate rocks, |
