摘要
Abstract
Determination and calculation of magnetic parameters of rocks and minerals are faced with some problems such as ambiguous location determination, incorrect units of Ta, ID confusion of specimen surface and negative magnetic susceptibility. On the basis of previous studies and starting with determination of Gauss position using mechanical magnetometer and formula derivation, this paper first analyzed the difference in principles between proton-type magnetometer and mechanical magnetometer, and then clearly explained Gauss first position, Gauss second position, the number of specimens surface, the order determination and unit of geomagnetic field. The cause of negative magnetic values were also analyzed and the measures for improvement were put forward. The results obtained can be of some help to the determination and calculation of magnetic parameters of rocks and minerals.关键词
