| 摘 要： | 硅质岩是一类广泛分布于造山带内的岩石,其组成简单且具有较高的稳定性.然而,硅质岩的这种高稳定性是宏观的,在微观上仍然会保留地质演化和成岩过程的痕迹,可以从中提取造山带演化过程中的温度、压力和流体等重要信息.秦岭造山带西段八方山一二里河Pb-Zn矿区的赋矿硅质岩的光学显微镜、激光拉曼(RAMAN)、X射线粉晶衍射(XRD...

| Abstract: | The chert,with simple component and high stability,is widely distributed in orogenic area.It's stable in macroscopic traces,however,such traces showing geological evolution and diagenic metamorphism of large scale orogeny can be found by the microfabric study,as temperature,pressure and fluids.The ore-hosting chert from Bafangshan-Erlihe Pb-Zn ore deposit is studied by optical microscope,RAMAN,XRD and SEM-EDS.It is indicated that the chert was of obvious alteration during the orogeny,metallogenesis and recr... |
