“…We therefore speculate that the Baizhangzi gold deposit, one of the typical IRGDs, was also formed in the Late Triassic. It was also demonstrated by a number of investigated gold deposits hosted by igneous rocks, including Bilihe , Daxiyingzi (Liu et al 2021), Julia (Soloviev et al 2022) and Xiajinbao . Defant and Drummond (1990).…”

“…The characteristics of the latter two types are the relationship between the structural setting and their ore-forming process (Cepedal et al 2013;Tuduri et al 2018), for instance, the Fuwen Audominated Au-Ag deposit (Xu et al 2017) and Num˜ao gold deposit (Leal et al 2022). However, the intrusion-hosted deposits are characterized by the direct effect of magmatism on gold mineralization (Lang & Baker, 2001), such as the Linares deposit (Cepedal et al 2013), Bilihe gold deposit ) and the Julia deposit (Soloviev et al 2022). The IRGDs have been intensively studied, and the role of magmatism in gold mineralization is a subject of debate.…”

“…However, there is a consensus on the basically consistent time of magmatism and mineralization (e.g. Liu et al 2021;Soloviev et al 2022). In summary, four different aspects have been stressed: (1) the origin of magma, such as reworking of an ancient crust is related to the formation of gold in the Argun massif (Liu et al 2022); (2) fractional crystallization, for instance, highly fractionated quartz diorite porphyry is related to the Bilihe gold deposit ); (3) composition (type, volatiles, K 2 O content and alkalinity), for example adakitic granitoids have genetic links to the Fuwen Au-Ag ore deposit (e.g.…”

The relationship between magmatism and gold mineralization has been a topic of interest in understanding the formation of ore deposits. The Baizhangzi gold deposit, located in the northern margin of the North China Craton, is hosted by the Baizhangzi granite (BZG) and provides a case to evaluate the relation between granite and gold mineralization in Late Triassic. In this study, we present petrography, bulk geochemistry, zircon U-Pb isotope and trace elements data, as well as major elements of biotite and plagioclase for the BZG to evaluate the petrogenesis and link with gold mineralization. The BZG comprises biotite monzogranite, biotite-bearing monzogranite and monzogranite (BZGs). Zircon U-Pb geochronology shows that all the granitoids of BZGs were coeval with a formation age of 232 Ma. The granitoids, with high SiO2, Al2O3 and Sr, while low Y and Yb, show adakitic affinity. They are enriched in LILFs (e.g., Rb, Ba, Th, U and Sr) and LREEs, while depletion in HFSEs (e.g., Nb, Ta, P and Ti). The geochemical and mineral chemical data suggest that the granitoids have experienced the fractional crystallization of biotite + plagioclase + K- feldspar + apatite. Crystallization temperature is estimated as ca. 700°C, and pressure is between 0.71 kbar and 1.60 kbar. The monzogranite shows higher values of logfO2, △FMQ and △NNO than the biotite-bearing monzogranite, ranging from −19.76 to −11.71, −4.93 to +3.67 and −5.48 to +3.11, respectively. The fractional crystallization, together with high fO2, K-metasomatism and low evolution degree, provided favourable conditions for gold mineralization.
