Hydrothermal alteration and mineralization of Baiyun gold deposit in Liaodong Peninsula, North China Craton

Abstract: Baiyun deposit is a large gold deposit in the Liaodong Peninsula (North China Craton), containing over 31.7 t of gold. Silicic alteration, K-feldspar alteration, and pyritization are well developed and closely related with mineralization in Baiyun deposit. Based on field and optical microscopic observations, the alteration styles include quartz + K-feldspar zone, pyrite + sericite +quartz zone, and chlorite zone from orebody outward. In this study, the quartz, K-feldspar, and pyrite of pre-ore, syn-ore stages … Show more

“…2160-2100 Ma) (Figure 9). The meta-volcanic sequences are mainly outcropped in the North and South Liaohe Groups and characterized by bimodal volcanic rocks [21,40,77,78]. They display various lithologies, mainly composed of meta-rhyolite, meta-dacite, finegrained gneiss, amphibolite, and meta-basalt.…”

“…2.2-2.1 Ga mafic intrusions were identified in southern Jilin Province and on the Liaodong Peninsula [31,38,44,46,79]. Thirdly, the metavolcanic sequences in the JLJB are mainly composed of bimodal volcanic rocks [21,40,77,78], which indicates that the JLJB experienced an intra-continental rift rather than magmatic arc during the early Paleoproterozoic. Fourthly, a large number of Liaoji granites with an affinity of A-type granite also suggest an intra-continental rift setting [21,22,43,45,80].…”
