中国金成矿的大地构造背景

指出中国金成矿的三个大地构造特征，中国第一个岩金成矿高潮的地层时代（古元古代）晚于全球第一个岩金成矿高潮的地层时代（新太古代）；中国第二个岩金成矿高潮地层时代（中生代）早于全球等二个岩金成高潮的地层时代（新生代）；全球有一个围绕北极圈的砂金成矿区，中国另有一个青藏高原砂金成矿区。

TECTONIC SETTING OF GOLD METALLOGENESIS IN CHINA

Three tectonic characteristics in connection with gold metallogenesis in China are given in the present paper:the stratigraphic era(the Proterozoic)of the first metallogenetic culmination for lode gold in China is later than that(the Late Archaeozoic)of the world as a whole;the stratigraphic era (the Mesozoic)of the second one in China is earlier than that(the Cenozoic)of the world over;in addition to the placer gold metallogenetic megaprovince surrounding the Arctic Circle in the globe as a whole,there is another one existing in the Qinghai-Tibet Plateau in China.
