| 中文摘要: |
| 呵叻盆地与兰坪—思茅盆地同处藏滇印支褶皱系,成矿时代相同,析盐矿物组合类似。文章对比两者钾盐产出特征、成矿地质背景和成盐演化,分析两者成矿条件。建议在区域钾盐找矿工作中,应充分重视断陷盐盆地中有深卤补给的可能性,以及中、新生代碎屑岩系的盐盆地,如果成盐盆地规模较大,卤源补给丰富,古气候条件适宜,即使为陆源碎屑岩系,也仍有可能形成大型钾盐矿床。 |
| 英文摘要: |
| Both Khorat and Lanping-Simao basins are located in Yunnan-Tibet Indosinian fold system, have the same potash metallogenic epoch and similar mineral combination. Base on comparison of salt-sediment characteristic, metallogenic geological background and salt-sediment evolution between Khorat and Lanping-Simao basin, the metallogenetic conditions were analyzed. The authors suggest that the possibility of deep brine supply should be paid more attention in fault-depression basins and clastic salt basins of Mesozoic and Cenozoic during regional prospecting. If the salt-sediment basin is large enough, the source of brine is abundant and palaeoclimate is favorable, there is still possible to form the large-sized potash deposit in the clastic rock basin. |
