Diverse fluid sources and complex fluid flow paths in skarn systems appear to be well documented. Nevertheless, in situ microanalysis of oxygen isotopes by secondary ion microprobe (SIMS) in skarn minerals can provide further high spatial resolution information on this complexity and the formation of skarns and associated ore deposits. In this stud...

Carbonate-hosted Pb–Zn deposit frequently contain significant amounts of critical metals such as Cd, Ga, Ge, Tl, and In. However, the enrichment characteristics and chemical controls in different types of sphalerite within individual deposit remain poor constrained. Based on texture observations and in-situ laser ablation–inductively coupled plasma...

The Yangzhuang iron deposit is a Kiruna-type iron oxide-apatite (IOA) deposit within the Ningwu mining district of the Middle and Lower Yangtze River Metallogenic Belt (MLYRMB), China. This study applies a numerical modeling approach to identify the key processes associated with the formation of the deposit that cannot be easily identified using tr...

The Maoping large Pb-Zn deposit is located in the Sichuan-Yunnan-Guizhou Metallogenic Province (SYGMP), southwestern China, hosting more than 3 mt Pb and Zn minerals, with 140 t associated Ge. This study uses numerical simulation methods to explore the key factors of the mineralizing system that formed the Maoping deposit which traditional analytic...

Early Cretaceous granitic rocks are widespread in the southern Great Xing’an Range (SGXR) in the eastern part of the Central Asia Orogenic Belt where they have been interpreted to have formed by remelting of juvenile materials derived from a depleted mantle source. We present new U-Pb ages, geochemistry and Sr-Nd-Hf-O isotopic data for ~140 Ma gran...

The Haobugao Zn-Fe-Sn skarn deposit in the Southern Great Xing’an Range of NE China contains three generations of garnets that were distinguished using petrography. This paper discusses skarn formation and hydrothermal fluid evolution in the Zn-Fe-Sn skarn system based on the interpretation of diverse textures and compositions of garnets. Crystals...

The Hehuashan sediment-hosted Pb–Zn deposit is a large-scale (Pb + Zn＞1 Mt) deposit hosted in the Tongling mining district of the Middle-Lower Yangtze River belt (MLYB). The Pb–Zn ore bodies are composed of two main mineralization types, namely breccia type and massive type. The breccia type ore bodies are hosted by the Triassic limestone and dolos...

The Xuancheng ore district is a newly discovered ore district within the Middle and Lower Yangtze River Metallogenic Belt (MLYRMB) of Eastern China. This district contains numerous skarn–porphyry deposits and this study focuses on four intrusions associated with known skarn mineralization within this district, namely the Shizishan pyroxene diorite...

The Zhonggu orefield is located within the southern Ningwu volcanic basin and is one of the largest iron ore districts within the Middle–Lower Yangtze River Metallogenic Belt (MLYRMB) of eastern China. The area hosts the Gushan iron oxide–apatite (IOA) deposit and the Baixiangshan, Longshan, Hemushan, Zhongjiu, and Taipingshan skarn-type iron depos...

The Zhonggu ore field is located in the southern Ningwu volcanic basin, the largest iron ore district within the Middle–Lower Yangtze River Metallogenic Belt (MLYRMB) of eastern China. This area has produced more than 2000 Mt of iron ore although comparatively little research has been done on the ore-bearing intrusions in this region despite the si...

Hehuashan zinc-lead deposit is located in the Tongling district, which is one of the most significant ore districts of the Middle and Lower Reaches of Yangtze River Belt. The ore bodies of Hehuashan deposit are hosted by nodular limestone of Triassic Lower Nanlinghu Formation. There are two intrusions in Hehuashan deposit, with the lithology of dio...
