| 摘 要： | 贵州在海西—燕山构造旋回期同时受东南侧江南复合造山带和西南侧特提斯域的发展演化影响,从晚古生代开始发生陆内裂陷,三叠纪初转化为前陆盆地,燕山运动使贵州进入板内造山阶段,形成前陆盆地典型褶皱样式侏罗山式褶皱和浅层滑脱构造等。其裂陷盆地和前陆盆地控制了沉积型、喷流沉积型矿产资源的时空产出,代表性矿种有煤、锰、铝土矿、烃源岩及页岩气等。而以金锑砷汞、铅锌、软玉等内生热液型、沉积改造型矿产明显受浅层滑脱构造、板内岩浆岩控制。由于该时期贵州所处前陆盆地之构造位置,形成了贵州非常有特色的中低温成矿域。

| Abstract: | In Haixi-Yanshan tectonic cycle, Guizhou was influenced by Jiangnan composite orogenic belt in the southeast and Tethys in the southwest in the same time, the continent began to rift from Late Paleozoic, became forelandbasin in early Trias. Yanshan movement make Guizhou in the period of intraplate orogenic, formed Jura type of folding and shallow detachment structure which are the typical folding of foreland basin. The rifting basin and foreland basin controlled the spatial and temporal occurrence of sedimentary and eruptive mineral resources, such as coal, manganese, bauxite, and source rock and shale gas. The gold-antimony-arsenic-mercury, lead-zinc, nephrite and other endogenous hydrothermal, sedimentary transformation minerals were controlled shallow detachment and continental magma. Because the foreland basin position of Guizhou in this period, the special low-middle temperature metallogenic domain formed. |
