“…The age of the Shuikoushan granodioritic intrusions is approximately 163.2 Ma . (3) SE China hosts more than half of the world's W-Sn reserves, mostly concentrated in southern Hunan and Jiangxi, northern Guangdong, and Guangxi provinces (Chen et al 1992;Shen et al 1994;Mao and Li 1995;Yin et al 2002;Lu et al 2003;Li et al 2004bLi et al , 2007dMao et al 2004Mao et al , 2007Zhao et al 2005;Peng et al 2006;Gu et al 2007;Hua et al 2007;Yuan et al 2007;Zaw et al 2007). The W-Sn deposits are represented by Shizhuyuan W-Sn and Furong Sn polymetallic deposits in south Hunan, both of which are among the largest and economically important skarn-greisen-vein tungsten-polymetallic deposits in China (Mao and Li 1995;Yin et al 2002;Lu et al 2003).…”

“…The first group is stratiform sulfide deposits hosted by Late Carboniferous strata [5][6][7][8][9][10] (e.g. Xinqiao, Dongguashan, Tongguashan, Chengmenshan and Chengshan deposits).…”

“…In the MLYRB, a similar discordant veinlet and stockwork mineralization below the stratiform sulfide orebody generally is observed, and is thus considered as one of the most important pieces of evidence for the exhalative sedimentary origin of ore deposits [7,10,[16][17][18][19][20]. Previously, the timing of massive sulfide deposits was estimated by dating the minerals in the stratabound sulfide orebody [21][22][23][24][25].…”

“…In the past several decades, great attention has been given to the economic significance and distinctive geological features of these deposits. There are two distinctive models for the ore genesis of these deposits: (1) they are strata-bound skarn deposits associated with Yanshanian granitoids [1][2][3][4]; or (2) they are massive sulfide deposits formed by submarine exhalative sedimentation during the Late Carboniferous, and then altered by Yanshanian granitoid magmatism and related hydrothermal fluids [5][6][7][8][9][10]. Disagreements regarding these two models are focused on whether exhalative sedimentary mineralization existed.…”

The Xinqiao deposit is located in the Tongling area, Anhui Province. This deposit is dominantly composed of stratiform sulfide orebodies, which are restricted to the transitional zone from clastic rocks to carbonates at the base of the Late Carboniferous Huanglong Formation. There are discordant veinlets or networks of mineralization in the footwall rocks below the stratiform sulfide orebodies. The underlying discordant mineralization zones coexist with conformable stratiform sulfide orebodies, which are considered to be the most representative features of massive sulfide deposits formed by submarine exhalative sedimentation. This study reports a pyrite 187 Re-187 Os isotopic age of 319±13 Ma (MSWD=16) for the footwall mineralization zone. This isochron age is consistent with the interval of strata hosting the conformable stratiform sulfide orebody, and provides direct geochronological evidence for Carboniferous exhalative sedimentary mineralization.

SHRIMP and LA–ICP–MS zircon U–Pb dating, Nd and Hf isotope analyses, 40Ar/39Ar geochronology, and whole‐rock geochemistry indicate three episodes of magmatism in the Dabaoshan ore district, South China: (1) Caledonian dacites (ca. 438 Ma); (2) Indosinian dolerites (ca. 210 Ma); and (3) Yanshanian granodiorites/porphyries (ca. 165 Ma) and basalts (ca. 147 Ma). Episode 1 dacites and episode 3 granodiorites/porphyries are enriched in Rb, Th, U, and LREEs and depleted in Nb, Ta, Sr, P, and Ti. The dacites may have been derived from partial melting of Mesoproterozoic–Paleoproterozoic crustal material, whereas the granodiorites/porphyries were derived mainly from partial melting of a late Mesoproterozoic crustal source with minor inputs of mantle material, according to whole‐rock εNd(t) and zircon εHf(t) values. The geochemical characteristics of episode 2 dolerites and episode 3 basalts, as well as their positive εNd(t) values (3.3–5.9 and 3.5–4.0, respectively), suggest a depleted mantle source. Taking into account the tectonic evolution of the South China Block, we suggest episode 1 dacites and episode 2 dolerites formed in an extensional setting that resulted from lithospheric delamination during the Caledonian intraplate orogeny and orogenic collapse during the Indosinian intraplate orogeny. Episode 3 granodiorites/porphyries and basalts formed in a back‐arc extensional setting in response to the westwards subduction of the Palaeo‐Pacific Plate beneath the South China Block. The timing of the three episodes of magmatism coincides roughly with the published ages of mineralization in the Dabaoshan ore district, suggesting a genetic relationship.
