| 摘 要： | 层控式矽卡岩矿床中的矽卡岩和矿体主要顺地层呈似层状或透镜状产出，其矿物组合及矿物特征与一般的矽卡岩类似。成矿控制因素主要是地层层位、岩性和层间滑脱空间。成矿过程也分为矽卡岩期和石英硫化物期两期，成矿温度可高达390℃，其主要成矿机制是源自岩浆的热液沿层间发生渗滤扩散交代作用。

| Abstract: | he stratabound type skarn ore deposits are commonly seen in Tongling,Anhui Province.As an example,Datuanshan CuAu ore deposit is discussed in the paper.The characteristics of this kind of ore deposit that are different from common skarn one are as follow:(1)The skarn and ore bodies occur along the strata of the country rock as mainly quasistratiform .No alteration zoning between skarn and magmatic rocks can be seen as that in common skarn.(2)The major factors controlling oreforming processes are strata,lithology,magmatic rock and detachment among strata.(3)The oreforming mechanism is infiltrationdiffusion metasomatism.Other characteristics such as mineral assemblages,oreforming stages and temperature,salinity of oreforming fluid,etc.,are similar to those of common skarn ore deposits. |
