| 中文摘要: |
| 铝土矿是战略性大宗矿产铝与关键金属镓的主要提供者,当前随着国内外需求量的不断增大,铝土矿资源逐步短缺,加强对铝土矿资源的勘查和开发势在必行。虽然云南是国内重要的铝土矿资源基地,但相比于山西、贵州、广西等铝土矿资源大省,云南省铝土矿资源和勘查研究程度都逊色不少。最近的工作显示,云南铝土矿成矿潜力较大,找矿前景良好。因此,亟需对云南铝土矿成矿规律和找矿远景进行剖析,为找矿工作部署提供理论依据。本文系统梳理了云南省铝土矿资源特点和勘查成果资料,初步总结了云南省铝土矿的时空分布规律和成矿机制,并提出了找矿远景和方向。研究认为,云南省铝土矿床以沉积型和堆积型为主,空间上主要分布于滇东南、滇中、滇东北及滇西四区,成矿时代集中于中—晚二叠世及第四纪,具多期次、多因素叠加特征。综合成矿条件和规律分析,本文提出滇东南、滇中、滇东北、滇西 4个找矿远景区,圈定 I级远景区 6处、II级 9处、III级 1处,明确了重点勘查方向,助推云南省铝土矿找矿新突破。 |

| Bauxite is the main supplier of strategic bulk mineral aluminum and key metal gallium. Currently,with the increasing demand at home and abroad, China's bauxite resources are gradually becoming scarce, and it isimperative to strengthen the exploration and development of bauxite resources. Although Yunnan is an importantbauxite resource base in China, compared to provinces with large bauxite resources such as Shanxi, Guizhou, andGuangxi, the level of bauxite resources and exploration research in our province is significantly inferior. Recentwork shows that Yunnan bauxite has great potential for mineralization and good prospecting prospects. Therefore, itis urgent to analyze the mineralization laws and prospecting prospects of Yunnan bauxite, to provide theoretical ba.sis for the deployment of prospecting work. This article systematically reviews the characteristics and exploration re.sults of bauxite resources in Yunnan Province, summarizes the spatiotemporal distribution patterns and formationmechanisms of bauxite in our province, and proposes prospecting prospects and directions. Research suggests thatbauxite deposits in Yunnan Province are mainly of sedimentary and accumulative types, and are mainly distributedspatially in the southeastern, central, northeastern, and western regions of Yunnan. The mineralization period is con.centrated in the middle to late Permian and Quaternary, with characteristics of multiple periods and multiple factorssuperimposed. Based on the analysis of comprehensive mineralization conditions and laws, this article proposes fourprospecting areas in southeastern Yunnan, central Yunnan, northeastern Yunnan, and western Yunnan, delineating6 Grade I prospective areas, 9 Grade II prospective areas, and 1 Grade III prospective area, clarifying the key explo.ration directions, and promoting new breakthroughs in bauxite prospecting in Yunnan Province. |
