摘要
肖家营子钼多金属矿床是位于华北地台北缘燕山斑岩铜（钼）矿带东段的大型斑岩-矽卡岩型钼多金属矿床。与成矿作用有关的辉长辉绿岩-斑状细粒闪长岩时代属燕山期（177～113Ma）。以钼为主的多金属矿体主要赋存在辉长辉绿岩-斑状细粒闪长岩体的内外接触带。围绕着岩体呈半环形偏心式分布。该斑岩体较我国典型斑岩钼矿床金堆城、兰家沟等成矿岩体明显偏基性，研究其地质特征对进行华北地台北缘燕山斑岩铜（钼）矿带地质找矿具有重要的现实意义。
xiaojiayingzi molybdenum - polymetallic deposit is a large scale of porphyry - skarn deposit with located on the eastern of yanshan porphyry copper（molybdenum） ore belt of the norther borderland of north china platform . gabbro - diabse and porpyritic fine grain diorite is mainly associated with metallogenesis. Belong to yanshan era. molybdenum ore body with poly metallic as associated components located at the alteration zone of the gabbro-diabse, ore - body - showing porpyritic the half circle shape around the porphyry. Compare with other metallogenesis instrument such as jinduicheng, lanjiagou, xiaojiayingzi porohyry showing the basic.
The geological characters is studies. It is belired that would be great importance to guide geological searching in yanshan porphyry copper（molybdenum） ore belt of the northern borderland of north china platform.
