摘要
本文根据柴达木地块中上侏罗统砂岩和犁地块寒武、奥陶系灰岩中的磁黄铁矿的剩磁研究,指出了磁黄铁矿的剩磁稳定与否在于磁黄铁矿的成因差异。了解磁黄铁矿的剩磁稳定性,对于确定硫化矿床的矿化年代,解释磁异常以及确定某些地质构造问题和具有重要意义。
Abstract
Based on a study of remnant magnetism of pyrrhotites from Upper Jura ssic sandstone in Qaidam block and from Cambrian and Ordovician limestone in Ili block, this paper points out that the stability of remnant magnetism of pyrrhotites lies in their genetic differences. A knowledge of remnant magne tism stability of pyrrhotites is of great significance in determining minerali zation epochs, interpreting magnetic anomalies and solving some geological-stru ctural problems.
