| 摘 要： | 柴达木盆地北缘是重要的构造-岩浆活化带和内生矿产成矿带，现今大地构造性质属地穹列。地槽演化阶段加里东期幔源岩浆活动，地台演化阶段华力西期壳幔混染Ⅰ型岩浆侵入，以及地洼演化阶段印支期非造山A型花岗岩构成了该区构造-岩浆活动的三个成因系列。

DISCUSS FOR THE TECTONIC EVOLUTION AND MAGMATIC SERIES.IN THE NORTH MARGIN OF QAIDAM BASIN |
| |
| Abstract: | The north margin of Qaidam basin is a significant tectonic-magmatic activation belt and an endogenic metallogenic province. Its recent archi-tectonic property is a geodome series. Mantle-derived magmatic activities in the geosynclinal evolution stage, crust-mantle-derived I-type intrusions of the platform evolution stage, and non-orogenic A-type granites of diwa evolution stage constitute the main bodies of abundant tectonic-magmatic activities. In this paper, we classify tectonic-magmatic activity into three genetic series, so as tooffer some prospections about the economic development of the area on the basis of tectonic-metallogenic analysis. |
