摘要
本文从中国铜矿的地理分布出发,通过对矿点密度和断裂密度等值线的相关性分析,探讨了铜矿的空间分布及其与断裂带的关系,得出:断裂密度在(60,220)区间的铜矿点占总数的81.9%;在距断裂带20.76假定单元内(实际距离为86km)集中了大约83%的铜矿点。由此可见,断裂带与铜矿区带的展布有关,对铜矿床分布的控制作用明显。
From geographical distribution of the copper mine in China, with the method of isopleth about deposit density and fracture density, it is discussed that relationship between distribution of copper mineral deposit and fracture zone in China. The charts indicate 81.9% of the total amounts of copper mine lies in the belts, the fracture density of which is between 60 and 220. And 81.9% total amounts concentrates in the distance of 20.76 units （about 86 km） from fracture zone. In summary, the distribution of the copper mine mainly depends on fracture zone, and the effects of fracture zone to copper mine is obvious.
