| 中文摘要: |
| 云南省开远地区位于南盘江克拉通盆地内，是滇东南地区传统的优质富锰矿产区。通过对云南省开远地区沉积型锰矿地质特征以及区内典型锰矿床研究，结合研究区遥感矿化蚀变信息特征、水系沉积物地球化学特征，系统总结了区内含锰岩系法郎组的成矿特征及找矿标志，在研究区内圈出了两个锰矿找矿远景区，通过地表山地工程验证，取得了较好的找矿成果，为在区内寻找锰矿指明了方向。 |
| 英文摘要: |
| The Kaiyuan region is located in the Nanpanjiang craton basin, which is a traditional high-quality manganese-rich region in southeast Yunnan. This work studied the geological characteristics of sedimentary manganese deposits and typical manganese deposits in the Kaiyuan area of Yunnan Province. Combined with the characteristics of remote sensing mineralization alteration information, geochemical characteristics of stream sediments, the metallogenic characteristics and prospecting criteria of the Falang Formation of manganese bearing rock series were systematically summarized in the area. Two manganese prospecting spots were delineated in the study area, which have achieved ideal prospecting results through verification by surface mountainous engineering. This study provides direction for prospecting manganese deposits in the area. |
