Geology, geochemistry, and genesis of the Dashui Carlin‐type gold deposit in the West Qinling orogenic belt, Gansu Province, China

Abstract: The Dashui gold deposit occurs in the south of West Qinling orogenic belt where is belonged to a famous gold triangle area named “Shan‐Gan‐Chuan” in Northwest China. The presence of native Au associated with hematite alteration is unique in China. The ore bodies at Dashui mainly occur in the limestone and dolomitic limestone units within the Lower Triassic Maresongduo Formation. The granodioritic dykes that intrude the Triassic sedimentary rocks are locally mineralized because of later carbonate alteration. Th… Show more

“…The Zaozigou deposit lies in the central gold belt of West Qinling. The Dashui gold deposit is the representative Carlin‐type gold deposit in this belt (Peng et al, ). The Dashui deposit is hosted in Middle Triassic shallow marine carbonate rocks and younger igneous dykes.…”

“…There are more than 50 gold deposits of varying scales were discovered over the past decades (Figure 1c; Chen et al, 2004; Zeng et al, 2012). Typical deposits are Yangshan (>300 t, Liang et al, 2014; Yang et al, 2016), Zhaishang (127 t, Liu, Dai, et al, 2015), Baguamiao (106 t, Wang et al, 2020), Dashui (>100 t, Peng et al, 2018; Wang et al, 2019; Zeng et al, 2013), Liba (79 t, Zeng et al, 2012), Daqiao (>105 t, Wu et al, 2018, 2019), Zaozigou (142 t, Sui et al, 2020) and Shuangwang (>70 t, Wang et al, 2015; Liu et al, 2021). Most of these gold deposits are hosted within early Palaeozoic to Triassic, unmetamorphosed to weakly metamorphosed clastic and carbonate rocks (Hu et al, 2022; Liu, Liu, et al, 2015).…”

“…The genetic types of some of these gold deposits are still controversial. Based on the disseminated style of mineralization, alteration, the submicroscopic state of gold and the geochemical association of the Au‐As‐Hg‐Sb, some deposits were classified as the Carlin‐type gold deposit (Liu et al, 2014; Peng et al, 2018) or the Carlin‐like gold deposit (Liu et al, 2018; Liu et al, 2019; Liu, Dai, et al, 2015; Liu, Liu, et al, 2015). However, in view of their relationships to faults and shear zones and to the enrichment of CO 2 , many gold deposits were recognized as orogenic gold deposits (Li et al, 2018; Liu et al, 2016; Sui et al, 2018; Yang et al, 2016; Yu, Qiu, Nassif, et al, 2020; Yu, Qiu, Sai, et al, 2020; Zhou et al, 2014).…”
