Abstract

The Jiama mining area in Tibet is one of the most important large deposits in the eastern Gangdise porphyry copper belt. There are many kinds of rocks, and the physical properties of different strata and intrusive rocks are complex and diverse. In the past, due to the lack of enough attention to the physical properties of rocks, the types of rock determination were not comprehensive enough, and there was a lack of systematic and complete understanding of the physical properties of rocks in the Jiama mining area. On the basis of an analysis of rock physical property data in the past and through the physical property measurement and statistical analysis of core samples from six typical boreholes in the Jiama mining area, the characteristics of rock density, magnetism, resistivity and polarizability in the mining area were summarized, and the rock geological geophysical model of the mining area was established, which provides a reliable basis for the subsequent geophysical work in the mining area. Secondly, the rock electrical parameters were used to correct the static effect measuring points on the magnetotelluric sounding profile in the mining area so as to provide the basis for the magnetotelluric sounding profile interpretation and guide the magnetotelluric data processing and interpretation in the mining area. Through the comparison and verification of drilling data, good exploration results were achieved.

Key words： Jiama mining area petrophysical property determination petro-geological geophysical model magnetotelluric sounding
