Intrusion-related stratabound deposits within Late Carboniferous carbonate units are an abundant and highly economically significant ore type in eastern China. In such deposits, stratabound mineralization commonly coexists with porphyry and/or skarn mineralization, and the vast majority of reserves (> 90%) are derived from extensive stratabound ore...

Stratabound deposits are widely distributed along the Middle-Lower Yangtze River metallogenic belt (Eastern China). The stratabound mineralization system in these stratabound deposits remains enigmatic as to whether it is associated with late Mesozoic intrusions or late Carboniferous sedimentary exhalative processes. Dongguashan is a typical strata...

The Huayuan orefield in the SW Yangtze Block (SW China) is a world-class Pb-Zn orefield, with over 20 million tonnes (Mt) metal reserve. However, the Pb-Zn ore fluid source and evolution in Huayuan remain controversial. This study determined the major and trace element compositions of the newly-identified apatite from the Pb-Zn ores, using electron...

The Huanggangliang Fe-Sn deposit is located in the southern Da Hinggan Range (NE China), and it’s one of the most important deposits within the Huanggangliang-Ganzhuermiao Sn polymetallic metallogenic belt. Nearly 90% of the orebodies (stratiform/lenticular) at Huanggangliang are hosted in the Lower Permian andesite or marble. Three ore deposit typ...

Dongguashan is one of the largest Cu-Au deposits in eastern China, with ubiquitous garnet in the stratiform and skarn orebodies. The stratiform ore-formation remains enigmatic. In this study, we describe the diverse textures and present new U-Pb age and chemical data for the Dongguashan garnet. Garnet in the skarn orebody can be divided into three...

In-situ LA-ICP-MS and S isotopes of pyrite from the Baoshan Cu polymetallic deposit were conducted to investigate the ore-forming process and the enrichment mechanism of elements. Three generations of pyrite (Py I, Py II, and Py III) in the skarn-type ores and pyrite in the carbonate-hosted sulfide ores from central, western, and northern (C_Py, W_...

In this study, the dominant geological factor that influences the element distribution in sphalerite was determined and the behaviors of the elements under a single factor were investigated (e.g., temperature). To this end, two multivariate statistical analysis methods, namely, principal component analysis (PCA) and factor analysis (FA), were perfo...
