摘要
本文对粤北大沟谷碎裂钠长石岩型富金矿床的地质特征进行了初步总结。概括了韧－脆性剪切带的宏、微观特征和演化趋势，论述了剪切带中的钠长石化与金矿化的关系，把钠长石化划分为３个阶段和５个期次，并叙述了不同发展阶段钠长石的构造条件、结构构造、含矿性和蚀变特点，归纳出含矿钠长石岩的基本特征。
This is a preliminary summation of the geological features of the cataclastic albitite type gold deposit in Dagougu area,northern Guangdong Province. With a general description of the macroscopic and microscopic features of the ductile-brittle shear zone and its evolution,and also a discussion on the relation between albitization and gold mineralization.The albitization is divided into three stages and five phases. The tectonic condition for albitization,the texture and structure of the albite,its alteration and its content of gold in the different stages are dealt with.
