| 摘 要： | 华北地台区构造作用具有多期次板块俯冲和碰撞，是金矿形成的有利条件。深大断裂在成岩成矿中占重要地位。地台活化主要表现为燕山—喜山期构造和岩浆活动对原有地质构造和金矿化进行了强烈的改造。本区有利的找矿方向是地台边缘金矿集中区。

| Abstract: | The tectonism of North China platform had the multistage plate subduction and collision which form a favourable condition for gold mineralization.Deep and large fault system played an important role in lithogeny and metallogenesis.The main activity of platform are that the original geological structure and Au were reformed intensely by Yanshan-Xishan period structure and magmatic activity.The favourable prospecting criteria in this region is gold deposits concentration area near the margin of platform. |
