伊春地区铅锌多金属矿的航磁异常特征分析与研究
|
摘要
由于伊春地区连年开采,矿山的保有储量愈来愈少。为加快伊春地区铅锌多金属矿产资源的勘查,笔者在系统分析已知矿床的成矿地质背景、成矿条件等基础上,对相关矿床的航磁异常做了适当的转换处理和分析,归纳并提取了矿床的航磁标志,再结合相关成矿地质条件分析,可快速识别具有找矿前景的航磁异常。通过两个航磁异常的查证,均发现了较好的物、化探异常,槽探揭露的矿化带(体)进一步表明,该航磁标志具有较好的实用性,可作为伊春地区寻找铅锌多金属矿的一条找矿线索。
Owing to mining in the past successive years,the reserves have become less and less in Yichuan area. In order to speed up exploration of lead-zinc polymetallic deposits,the authors systematically analyzed metallogenic geological background and ore-controlling conditions of known deposits in Yichuan area,conducted proper conversion processing and analysis of the aeromagnetic data of the related deposits,and inferred and extracted aeromagnetic indicators of the deposits. Combined with the analysis of metallogenic geological conditions,the aeromagnetic anomalies with prospecting potential could be quickly identified. With two examples of aeromagnetic anomaly inspection,the better geophysical and geochemical anomaly features were found. The mineralization belt( body) exposed by trenching shows that the aeromagnetic indicators have high practicality and can be adopted as clues in search for the same type of lead-zinc polymetallic deposits in Yichuan area.
