通过野外地质调查和同位素年代学研究 ,结合前人资料 ,建立起铜陵地区燕山期岩浆流体系统的时空格架及岩浆活动与矿产的关系。将铜陵地区的岩浆流体系统分为两类 4个子系统。一类是与燕山期 (15 0～ 133Ma)侵入岩有关的铜陵侵入岩岩浆流体系统 ,受近东西向铜陵_南陵基底断裂控制 ,依据其活动时间先后和流体活动特征 ,可进一步划分为早、晚 2个流体子系统 ;另一类是与燕山晚期 (12 2～ 110Ma)繁昌盆地火山岩有关的火山岩流体系统 ,受北东侧凹陷盆地控制 ,与“宁芜式”玢岩铁矿和金矿关系密切 ,包括 2个子系统。各子系统又包括不同的流体单元 ,流体单元是填图的基本单位。岩浆岩自身可形成独立矿床 ,同时 ,对海西期同生沉积矿床或矿胚层叠加改造 ,增补铜、金等成矿物质 ,使层状矿体变富 ,规模变大 ,在铜陵地区形成全球特有的大型_超大型矽卡岩型铜矿床。
Through the field geological survey and isotope chronology, combined with the previous data, the relationship between the magmatic activity and mineral assemblages of the Yanshanian magmatic fluid system in Tongling area was established. The magmatic fluid system in Tongling area is divided into two types and four subsystems. One is the Tongling intrusive magmatic fluid system related to the Yanshanian (15 0 ~ 133 Ma) intrusive rock. It is controlled by the Basis Fault of the Near East-West Tongling-Nanling. According to its activity time and fluid activity characteristics, it can be further divided into early- And two fluid subsystems. The other is a volcanic fluid system related to the volcanic rocks of the Fanchang basin in the late Yanshan Period (12 2 ~ 110 Ma). It is controlled by the sag basin on the north east side and connected with the “Ningwu” Close, including two subsystems. Each subsystem also includes different fluid units, fluid units are the basic units of mapping. The magmatic rocks can form an independent deposit by themselves. At the same time, superposition and remodeling of synsedimentary deposits or ore-bearing mesosols in the Hercynian period have increased ore-forming materials such as copper and gold to make the layered ore-bodies become richer and larger in scale, forming a global Unique large-super large skarn copper deposit.
