A Novel Three‐stage Tectonic Model for Mississippi Valley‐type Zn‐Pb Deposits in Orogenic Fold‐and‐Thrust Belts

Yucai Song

Abstract Mississippi Valley‐type (MVT) Zn‐Pb deposits predominantly form within both orogenic forelands and fold‐and‐thrust belts, yet the mineralization process within the latter tectonic setting remains inadequately understood. This study, through a comprehensive review of MVT deposits across global fold‐and‐thrust belts, introduces a …

Genesis of Gypsum/Anhydrite in the World-Class Jinding Zn-Pb Deposit, SW China: Constraints from Field Mapping, Petrography, and S-O-Sr Isotope Geochemistry

Gang Huang, Yucai Song, Liangliang Zhuang, Chuandong Xue et autres

The world-class Jinding deposit in SW China has ~15 Mt of Zn and Pb metals combined, in an evaporite dome containing amounts of gypsum/anhydrite. These gypsum and anhydrite are mainly located in limestone breccias (Member I), gypsum-bearing complexes (Member III), and red …

Metal sources and fluid pathways of karst-hosted Mississippi Valley-type Zn–Pb deposits in the fold-thrust belt: A case study of the Changdong deposit in the southeastern Himalayan-Tibetan orogen

Longlong Yue, Yingchao Liu, Yucai Song, Wang Ma et autres

The metal sources and fluid pathways for Mississippi Valley-type (MVT) Zn–Pb deposits in fold-thrust belts remain open topics of debate. To develop a more comprehensive understanding of these issues, this study presents the sulfide morphology, S and Pb isotopes, and trace element …

Vanished evaporites, halokinetic structure, and Zn-Pb mineralization in the world-class Angouran deposit, northwestern Iran

Liangliang Zhuang, Yucai Song, David N. Leach, Yingchao Liu et autres

The Angouran deposit (19.3 Mt at 23.4% Zn and 4% Pb) is the second-largest Zn-Pb deposit in Iran. The deposit is hosted in a Neoproterozoic−Cambrian marble-schist sequence within a breccia pipe in a domal structure, with sulfide mineralization under low-temperature hydrothermal conditions …

The Characteristics and Origin of Barite in the Giant Mehdiabad Zn-Pb-Ba Deposit, Iran

Yingchao Liu, Yucai Song, Mahmoud Fard, Zengqian Hou et autres

Abstract Mehdiabad is the world’s largest Mississippi Valley-type (MVT) Zn-Pb deposit (394 million tonnes [Mt] of metal ore at 4.2% Zn, 1.6% Pb) and contains significant barite resources (>40 Mt). Such large accumulations of barite are not common in carbonate-hosted Zn-Pb deposits. …

Characteristic and genesis of dolostone reservoirs around the Proterozoic/Cambrian boundary in the Upper Yangtze block for Mississippi valley-type Zn-Pb ores: A review

Li-Dan Tian, Yucai Song, Liangliang Zhuang, Zengqian Hou et autres

Reservoirs as the direct targets for hydrocarbon exploration represent the permeable and porous rocks. In this sense, reservoirs provide the crucial control for Mississippi Valley-type (MVT) Zn-Pb ore formation, but they have received less attentions in the research field of MVT deposits. …

INFLUENCE OF ORGANIC MATTER ON Re-Os DATING OF SULFIDES: INSIGHTS FROM THE GIANT JINDING SEDIMENT-HOSTED Zn-Pb DEPOSIT, CHINA

Shiqiang Huang, Yucai Song, Limin Zhou, David L. Leach et autres

Abstract This study evaluates the effect of organic matter impurities on pyrite Re-Os dating, using the giant Jinding sediment-hosted Zn-Pb deposit in China as an example. The Jinding deposit is hosted in a Paleocene evaporite dome that was a hydrocarbon reservoir before …
