为了解浙东山门地区铜矿床的分布规律及地质特征，并对该地区铜矿床进行找矿预测，首先系统分析了区内地质、物化遥特征，然后对产出于该地区的半岭—黄施岙一带铜矿床(山门铜矿床)的产出状态、地质特征、矿化类型、围岩蚀变、控矿因素进行了详细讨论，结果表明：①区内铜矿床成矿的同时具有浅成热液和斑岩成矿系列的某些特点，简单地以构造热液充填或典型的斑岩成矿理论指导找矿是不合理的，应以与次火山岩有关的浅成热液型铜多金属矿作为主攻对象；②矿区所见矿化大多属高位或远端的矿化，其延深部位是现阶段找矿的主要目标，而斑岩成矿则可能在更深处。在上述分析的基础上，提出了矿区“五位一体”的找矿模式，即针对NW向断裂裂隙带、次级火山机构、多期次的潜火山-侵入岩、蚀变分带特征和物化探异常等5种不同的矿化类型提出了具体的找矿思路，为区内矿产勘查工作提供参考。

The ore-forming geological conditions of eastern Zhejiang volcanic depressions is good,a large number of cop-per-gold polymetallic deposits are distributed in this area. In order to understand the distribution regularity and geological char-acteristics of the copper deposits in this area and conduct prospecting prediction of the copper deposits in this area,firstly,the regional geological characteristics and physical, chemical, remote sensing characteristics of Shanmen area, eastern Zhejiang province are analyzed in depth;then,the output condition,geological characteristics,mineralization type and ore-controlling fac-tors of the Shanmen copper deposit that is located in Banling-Huangshiao area in Shanmen area,eastern Zhejiang province are discussed in detail. The reslts show that:①the copper deposit mineralization in this area with certain characteristics of epither-mal and porphyry metallogenic series,so,it is unreasonable to adopt the tectonic hydrothermal filling or typical porphyry metal-logenic theory to guide the prospecting work in this area,the epithermal type copper polymetallic deposits related to the sub-volcanic rocks should be taken as the main prospecting object;②most of the mineralization happened in the mining area are high mineralizaiton or distal mineralization,the extending area of the mineralization is the main prospecting goal,the phenome-non of porphyry mineralization may be happened in deeper place. Based on the above results,the prospecting pattern of "one whole with five pars"is proposed,that is to say,the detailed prospecting ideas of the five kinds of mineralization types( NW-di-rection fault fracture zone,secondary volcanic institutions,multi-stages latent volcano-intrusive rocks,alteration zoning charac-teristics and geophysical-geochemical anomalies) ,to provide reference for the prospecting work in this area.
