苇沙河岩体位于吉林省东部著名的老岭金及多金属成矿带南段,附近有金厂沟、复兴屯中型金矿及翁圈里等若干小型金矿。笔者在2015年~2016年金矿详查工作中,在苇沙河岩体南缘内接触带发现了一处小型金矿,本文从岩体特征入手,从岩体上侵就位、冷却收缩过程,分析与金矿的成因关系。

The luosha river rock body is located in the South section of the famous laoling gold and metallogenic belt in the eastern part of Jilin province. There are several small gold mines in the vicinity, such as the medium-sized Jinchanggou gold mine, the medium-sized Fuxingtun gold mine and the wengjianli gold mine. In the detailed investigation of gold mine in 2015-2016, a small gold mine was found in the contact zone of the southern edge of the vixahe rock mass. This paper starts from the characteristics of rock mass, analyzes the relationship between the gold deposit and the invasion and cooling contraction process.
