| 中文摘要:本文在野外调查及相关资料分析的基础上, 对云南筇竹寺组的地质特征及产于其黑色岩系中的钼(镍)矿化特征做了初步分析, 对云南东部筇竹寺组黑色岩系钼(镍)矿找矿前景做出了初步预测。对钼(镍)的找矿方向、牛蹄塘组与筇竹寺组的对比分析、钼(镍)矿床后生变化、黑色岩系多金属成矿时代等问题进行了初步讨论、分析。本文认为, 筇竹寺组黑色岩系钼(镍)多金属矿的找矿方向, 应为云南马龙—曲靖麒麟区—沾益—会泽—巧家(南北向)—永善及镇雄—贵州西北部(北东、北东东向)一带。初步估计云南省中东部地区筇竹寺组黑色岩系钼、镍金属远景资源量在一百万吨以上。 |

| Abstract:Based on field survey and an analysis of relevant data, the authors preliminarily analyzed geological features of the Qiongzhusi Formation and characteristics of Mo (Ni) mineralization in black rock series, made a tentative prognosis of the Mo (Ni) ore-searching prospect in the black rock series of Qiongzhusi Formation in southeastern Yunnan, and also made a tentative discussion and analysis of the Mo, Ni ore-searching orientations, the correlation between the Niutitang Formation and the Qiongzhusi Formation, the epigenetic variation of the Mo (Ni) deposits, and the ore-forming epoch of the polymetallic deposits in black rock series. It is held that the ore-searching orientations for Mo (Ni) polymetallic deposits in black rock series of the Qiongzhusi Formation should be concentrated on Malong–Qilin of Qujing–Zhanyi–Huize–Qiaojia (in NS direction) –Yongshan and Zhenxiong in Yunnan–northwestern Guizhou (in NE, NEE directions). The preliminary estimation shows that the Mo, Ni metallic prospective resource quantity of the black rock series in the Qiongzhusi Formation of central and eastern Yunnan Province should be in excess of one million tons. |
