Abstract
The Laiyuan complex rock mass is an important part of the Yanshanian magmatite belt in eastern China,which hosts intense diverse mineralization evidenced by many types of ore deposits such as porphyry,skarn,and hydrothermalones,called " integration of multiple types".The accompanying ore-forming elements are molybdenum,copper,iron,lead,zinc,gold,silver and so forth.Four large and 5 medium sized mineral deposits have been identified,which are the main concentration areas of nonferrous metals in Hebei province.The porphyry copper-molybdenum deposits are controlled by the hypabyssal diorite porphyry of high emplacement,rhyolite porphyry and other small rock stocks.The intermediate acid intrusive rocks which were emplaced in media of shallow crust are closely related with skarn and hydrotherm iron,copper,lead,zinc,gold and other metals.Fault and contact zones are the main ore-control structures,and the ore-hosting rocks have also some control on mineralization.There is a close relationship between calcium skarn and copper ore,magnesium skarn and iron-lead-zinc polymetal.At the same time,this paper presents a review on characteristics of various ore deposits,including porphyry,skarn,hydrothermal and skarn superimposition,and hydrothermal types,and points out the prospecting direction of the Laiyuan complex rock mass in the future.关键词
