摘要
四川那朗地区地处三江成矿带,区内出露三叠系灰岩、板岩及火山岩,有闪长岩岩株侵入其中,地表见铁帽。岩体蚀变分带明显。通过激发极化法工作,由视极化率处理后异常显示,原始数据圈出了激电异常,推测为铁帽下部之矿(化)致异常。
Nalang area of Sichuan located in Sanjiang metallogenic belt, The region exposed Triassic limestone, slate and volcanic rocks, and diorite intruded.There is iron cap in surface. Rock alteration zoning evident. Through the induced polarization work done with polarization, anomalies after treatment showed that the raw data of the IP anomaly circle is due to the cap iron ore （mineralized）.
