摘要
山东平度滑石矿的成矿原岩为斜长角闪岩一大理岩，它们在含SiO2热液作用下在构造有利部位交代成矿。所形成的滑石矿分别继承原岩的特点。从大理岩→滑石矿体→斜长角闪岩具有明显的分带现象。以大理岩为原岩的矿石品质优良，以斜长角闪岩为原岩的矿石品级较低。
Mother rocks of Pingdu talc deposit in Shandong Province are amphibolite and marble. They formed talc ore in favourable area by SiO2-bearing hydrothermal, talc ore formed inherit characteristics of their respectively mother rock. It has obvious horizontal zoning from marble, talc ore body to amphibolite. Grade of ore formed from marble is higher, that formed from amphibolite is lower.
