地物化综合方法在六十里大沟地区矿产勘查中的应用

Application of comprehensive geo physical method in mineral exploration in sixty li dgou area

本文通过在六十里大沟地区开展激电中梯、高精度磁法、地质简测、土壤地球化学等综合性的测量工作,大致查明本区的成矿地质背景,缩小找矿靶区,为下一步的地表槽、井探和钻探验证提供依据。通过验证工作,在本区的泥鳅河组板岩中、浅成石英闪长玢岩中首次发现了热液型和超浅成低温热液型金矿(化)体及蚀变带。

In this paper, in the sixty li ditu area, the comprehensive measurement of the exciting medium ladder, high precision magnetic method, geological survey, soil geochemistry and so on is carried out. The metallogenic geological background of this area is roughly defined and the target area of the prospecting is narrowed, which provides the basis for the next step of surface trough, well exploration and drilling verification. Through the verification, the hydrothermal type and ultralow temperature hydrothermal type of gold （chemical） and alteration zones have been discovered for the first time in the loach diorite and diorite porphyrite in the loach River group of this area.
