Zhengguang gold deposit lies within Nenjiang County, Heilongjiang Province, is located at the southeast end of Duobaoshan Cu-polymetallic metallogenic belt and about 10km away from Duobaoshan porphyry copper deposit (Fig.1). Geotectonicaly, the deposit is located in the east segment of Xing'an-Mongolia fold belt in Paleo-Asian suture belt. By the end of 2013, the estimated gold reserves of the deposit amounted to 30t, reaching the scale of a large-sized gold deposit. Although outstanding achievements have been made in the exploration of the deposit, the geological study degree is relatively low. The existing studies focus mainly on the geological characteristics of the deposit, whereas no chronological study has been made, and less studies have been made in other aspects such as isotope. Now it is generally accepted that the metallogenic age of Zhengguang gold deposit is Yanshanian, and that it is closely related to diorite, belonging to a typical epithermal gold deposit (eg. Zhao Yuanyi et al., 2011).
