【摘要】 早前寒武纪克拉通内同样也发育地体构造和片状构造,这是由早期地幔热对流体系的动力学特点所决定的.本文通过对冀东青宽地区100km断面的研究,证实有四个早前寒武纪构造地层地体的存在,它们之间的相互拼贴起因于Ca.1.8Ga的 NW-SE向的斜向碰撞作用;根据合矿构造层变形作用的特点,可分为两类金的成矿系列:薄皮系列金矿床和厚皮系列金矿床.更多还原

【Abstract】 Terranes and slabs also predominated in early precambrian cratons, not exclusive in palaeozoic and onwards, they were supposed to result from the dynamical characteristics of early mantle-convection regime. It was concluded that four tectono-stratigraphic terranes existed and they were collaged because of ca. 1.8 Ga NW-SE oblique collision,based on a detailed study of a 100km transect across Qinlong-Kuanchen domain.According to the deformational characteristics of gold-hosted terranes, this paper has put up a new classification on gold mineralization, i. e. thin-skinned gold mineralization and thick-skinned series.更多还原
