The Hetai gold deposit(HGD) which is a typical ore deposit controlled by ductile shear zones, is the largest gold deposit in Western Guangdong and southeastern Guangxi. About the metallogenic epoch, it can be divided into mineralization during ductile process(Wang et al., 1989; Chen et al., 1993; He et al., 1993; Yao, 1995; Zhai et al., 2006; Zhu et al., 2011) and mineralization during brittle process (Wang et al., 1989; He et al., 1993; Chen et al., 1993; Zhang et al., 2001; Zhai et al., 2006). Now it is still lack of beneficial discussion on gold mineralization during brittle-ductile process in the HGD. A large number of studies show that, brittle-ductile deformation process is favorable for gold mineralization (Robert et al., 1986; Richard et al., 1988; Boullier et al., 1992). How about the mineralization during brittle-ductile process in the HGD? In order to discuss this question, distribution characteristics of lentoid silicalites and the relationship between lentoid silicalites and Au orebodies are observed under the shaft and by microscope.
