杨家杖子钼矿田位于著名的八家子-杨家杖子岩浆热液成矿带的中部,成矿带内由于沉积地层有利、岩浆岩发育、断裂构造复杂等一系列有利条件而形成了一大批大、中型钼矿床.以区域地质特征为基础,重点对矿田内最发育的兰家沟钼矿、杨家杖子钼矿和北松树卯钼矿成矿地质背景、矿床地质特征进行了详尽的研究,并结合成矿物质来源、成矿温度、成矿时代重新确定矿床成因,总结成矿主要过程,从而建立矿田区域成矿模式.在此基础上总结了杨家杖子钼矿田地质、物探、化探找矿标志.%The Yangjiazhangzi molybdenum orefield is located in the central area of the known Bajiazi-Yangjiazhangzi magmatic-hydrothermal mineralization belt, where numbers of large and medium-sized polymetallic deposits are formed in virtue of a series of favorable conditions such as advantaged sedimentary strata, developed magmatic rocks and complex fault structures. Based on the regional geological characteristics, metallogenic geological background and deposit geology of the orefield, the molybdenum deposits in Lanjiagou, Yangjiazhangzi and Beisongshumao are researched in detail. The genesis of the deposit is redefined with the mineral sources, ore-forming temperature and metallogenic epoch. A regional metallogenic model is established accordingly. Finally, the geological, geophysical and geochemical prospecting marks for molybdenum deposits in Yangjiazhangzi area are summarized.
