| 摘 要： | 川西南雷波卡哈洛磷矿床位于扬子准地台上扬子台褶带美姑-金阳陷褶束的中段,划属川西南成磷带雷波聚磷区,是典型的昆阳式沉积型磷块岩矿床,磷矿层赋存于下寒武统麦地坪组,通过对该区古构造、古沉积环境和古气候特征等的分析研究,认为古微地形地貌对矿体有良好的控制作用,提出"陆缘坻、古沉积环境、古气候与古微地貌"四位一体的成矿模式。这对研究区生产勘探工作具有一定的指导意义。

| Abstract: | Kahaluo phosphorite deposit, which locates in meigu-jinyang depression-folding beam of upper Yangtze Syneclise of Yangtze para-platform, is part of LeiBo phosphate accumulation area in Southwestern Sichuan ph osphate-metallogenic belt, and is a typical Kunyang-type sedimentary phosphate rock deposit. On the base of a nalyzing geological characteristics of Kahaluo phosphorite deposit, we investigate the metallogenic geological conditions as good as the ore distribution and then discover the importance of the metallogenic epoch micro-lan dform on controlling orebody＂ s spreading further. And this work promote us to propose a metallogenic model o f quaternity of margin islet, ancient sedimentary environment, paleoclimate and ancient micro-topography, whi ch is significant on exploration and mining of deposits in some extent. |
