| 摘 要： | 华北陆块北缘中段是我国金矿资源集中分布地区之一。区内不同时代不同类型金矿床集中产出 ,形成不同规模的金矿床密集区。它受控于区域构造格架的交叉区 ,在伸展 -挤压构造背景下产生的岩浆侵入 -基底隆升 -变质核杂岩 (或基底断隆 )三位一体的构造 ,成为整体上控制金矿床密集区的构造系统。变质核杂岩构造控制了绿岩型金矿成矿系列的时空结构

| Abstract: | The middle north margin of North China Block is one of the impotant areas where the gold resources are predominently distributed. In this area there are many kinds of gold deposits with different periods and scales. The large ones were found at the junctions of the regional tectonic network, which are trinity places of magatic intrusion basement uplift metamorphic core forming from the estension compression structure. They are the mainly tectonic system in the gold metallogenic focus areas. The metamorphic core complex structure controls the temporal spatial structure of green stone type gold mineral deposits metallagenic systeme. |
