| 摘 要： | 洞庭地洼西缘非金属矿产的产出特征与地槽、地台及地洼构造的演化具有密切的关系.地洼构造对区内大部分非金属矿产的形成和保存是极为有利的。在地洼盆地内常形成火山沉积蚀变矿床、盐类沉积矿床及生物沉积(能源和非能源)矿床等地洼沉积型非金属矿床。

ANALYSIS ON METALLOGENIC GEOTECTONICS OF NONMETALLIC ORES ON THE WESTERN MARGIN OF THE DONGTING DIWA |
| |
| Abstract: | There is a close relationship between occurrence of nonmetallic minerals and tectonic evolution of geosyncline,platform and diwa(geodepression)on the western margin of the Dongting diwa.Some results that(1) diwa tectonics is beneficial to forming and preserving nonmetallic minerals and(2)volcanogene-sedimentary alternation ore deposits, saline deposits and organosedimentary ore deposits can be often found in diwa basins are gained. |
