再论华南前震旦纪浅变质岩区区调方法

Further discussion of mapping method in South China outcroppedareas of pre-Sinian low-grade metamorphic rocks

章泽军等曾就华南前震旦纪浅变质岩区填图中存在的问题与填图方法进行了初步总结,以此为基础,针对华南前震旦纪浅变质岩变质浅、变形强的特殊性,从总体调研程序与内容、踏勘设计过程中的要点以及填图过程中如何把握宏观信息与宏观控制、成图过程中的综合分析等关键性问题进行了论述,以作为对浅变质岩区填图方法的补充。

This is a supplement for mapping method in South China outcropped areas of pre-Sinian low-grade metamorphic rocks. The authors analyse the low-grade metamorphic and strong deforming particularities of pre-Sinian rocks in South China,discuss the process and contents of geological survey,exploration scheme,gathering of geological information in field mapping and synthetical analyses in computer mapping.
