吉林省伊通县小黑顶子银矿地质特征及找矿标志

Geological features and prospecting criteria of the Xiaoheidingzi silver deposit in Yitong Manchu Autonomous County,Jilin Province

本地区通过对物化探资料的综合整理及地表工程的验证,在调查区大致查明了成矿地质条件,大致控制了主要矿体特征。区内新发现银矿(化)体3条,银矿(化)体受北西向断裂构造控制,矿石类型为石英脉。此次目的是通过地质工作和物化探工作的综合研究,找出该矿产地不同岩性中物理性质和化学性质的特征,总结出矿体的成矿规律,为进一步工作以及寻找同类型矿种提供线索。

Through the comprehensive organization of geophysical and geochemical exploration data and the verification of surface engineering in the local area,the metallogenic geological conditions of the deposit have been roughly identified in the survey area,and the main features of the orebody have been controlled.Three new silver ore bodies have been discovered in the area.The silver ore bodies are controlled by northwest trending fault structures,and the ore type is quartz vein type.Based on the comprehensive research on geological,geophysical and geochemical exploration work,identify the physical and chemistry characteristics of different lithology in the mining area;summarize the metallogenic regularity of the ore body,and provide clues for further work and the serch for similar types of minerals.
