冀北金矿成矿特征及成矿作用的分析

Metallogenic characteristics and mineralization of gold deposits in northern Hebei Province

我国冀北地区位于华北板块与西伯利亚板块之间,这一区域在地质演化史上属于断裂活动和构造岩浆作用的强烈活动带,受海西期和燕山期的构造回旋影响,经过多次剧烈改造,其地层特点是普遍存在褶皱,属于金成矿的有利地质背景。目前我国冀北地区大约拥有230多处大大小小的金矿点,其中包括1处超大型金矿,2处大型金矿和10处中型金矿。本文将对冀北地区的地层特点和金矿分布特点进行简单介绍,并再次基础上,分析冀北金矿的成矿特征和成矿作用。

In the area of China north Hebei plate and Siberia plate,this area belongs to the strong activity in the geological evolution of faulting and tectonic magmatism in the history of the band structure effects of cyclotron Hercynian and Yanshan period,after many dramatic transformation,the formation characteristics are common folds,favorable geological background is gold mineralization.At present,there are about more than and 230 large and small gold deposits in the northern Hebei Province,including 1 super large gold deposits,the largest gold deposits in the middle of the year and the middle size of the gold deposits in the 10 areas.In this paper,the characteristics of strata and the distribution of gold deposits in northern Hebei Province are briefly introduced.
