会理红盆砂岩铜矿成矿带的划分─—兼论二输找矿前景

Divisions of Mineralizing Belt for Sandston Copper Depositin Huili Red Basin and the Prospect for a Search for New Deposits

本文以矿带所处的吉地理位置，岩性岩相特点，含矿层的物质成分，矿体所处的具体构造部位，空间产出状态及展布规律，矿带中矿体的剥蚀与保留程度，矿体中的金属矿物分带特征等，为预测砂岩用矿矿区远景的依据，并提出了野竹实践中对６条原则的具体应用，将会理红盆西侧划分为３个成矿带，即西矿带、中矿带和东矿带。论述了３个矿带二输找矿前景。并预测了东矿带（新的矿带）及中矿带的一个有利成矿地段─—中矿带南段的爱国～湾子村段。

This paper summarizes the paleogeography localization of mineralizing belts, the characteris-tics of lithologic facies,the compositions of ore-bearing beds,ore body distributions in texture,de-nudation and residual degree of ore bodies,and the zoning characteristics of metallic minerals inore bodies. Based on six aspects mentioned above,the authors predict the potential district aboutsandstone copper deposit, and divide west Huili red basin into three mineralizing belts─thewestern,The middle and the eastern ones. The authors suggest the following prospecting ore dis-tricts─the eastern mineralizing belt and Eiguowan─ the southern part of mid-mineralizingbelt.
