Abstract
Abstract The connection between prolonged granitic magmatism and the formation of giant tungsten (W) polymetallic deposits has long been disputed. In this study, we present 6 mica Ar–Ar plateau ages and 22 molybdenite Re–Os model ages data on the newly discovered giant Dahutang W–Cu–Mo deposit in South China, which is one of the largest W deposits in the world. New and published zircon U–Pb, mica Ar–Ar, and molybdenite Re–Os age data reveal that the Mesozoic Dahutang magmatism and mineralization occurred in two major periods: (1) the Late Jurassic (ca. 153–147 Ma), forming the hydrothermal breccia, large wolframite-bearing quartz vein, and scheelite-dominated disseminated/veinlet type orebodies, which is mainly associated with the emplacement of porphyritic biotite granite; (2) the Late Jurassic to Early Cretaceous (ca. 146–130 Ma), forming the Cu–Mo–W ± Sn mineralization overprinting the Late Jurassic W–Mo ± Cu orebodies, which is mainly related to the successively emplacement of the Early Cretaceous granites. We suggest that continuous accumulation of mineralization for a long period of time (151–130 Ma) have contributed to the formation of the giant Dahutang deposit.

The formation of world class porphyry copper deposits reflect magmatic processes that take place in a deeper and much larger underlying magmatic system, which provides the source of porphyry magmas, as well as metal and sulphur-charged mineralising fluids. Reading the geochemical record of this large magmatic source region, as well as constraining the time-scales for creating a much smaller porphyry copper deposit, are critical in order to fully understand and quantify the processes that lead to...

Economically important porphyry Cu-Mo deposits (PCDs) are generally hosted by upper-crustal plutons of variable chemical compositions related to distinct geodynamic settings. The absolute timing and duration of pluton assembly and PCD formation are critical to understanding the genetic relationship between these interrelated processes. Here, we present new comprehensive zircon U-Pb and molybdenite Re-Os ages that tightly constrain the timing and duration of pluton assembly and the age of mineral...

Abstract Porphyry and skarn deposits in the middle Yangtze Valley within the Northern Yangtze Craton have a combined tungsten resource of ~ 3 million tonnes (Mt) and represent one of the most important tungsten regions in the world. The Dahutang porphyry tungsten deposit, with reserves of > 1 Mt, is one of the largest deposits. Uranium–Pb analyses for the ore-related granitoids yield ages of 147.4 ± 0.58 Ma–148.3 ± 1.9 Ma for porphyritic biotite granite, 144.7 ± 0.47 Ma–146.1 ± 0.64 Ma for fine-...

Porphyry dikes and hydrothermal veins from the porphyry Cu-Mo deposit at Butte, Montana, contain multiple generations of quartz that are distinct in scanning electron microscope-cathodoluminescence (SEM-CL) images and in Ti concentrations. A comparison of microprobe trace element profiles and maps to SEM-CL images shows that the concentration of Ti in quartz correlates positively with CL brightness but Al, K, and Fe do not. After calibrating CL brightness in relation to Ti concentration, we use ...

Abstract The Dahutang deposit is a newly discovered tungsten deposit, which is within the largest ones in the world with an estimated WO 3 reserve of 2 million tones. W-mineralization is considered to be related with the Late Mesozoic granites in the district. However, the precise emplacement ages, sources of these granites, and their relationship with mineralization are not well understood. In this study, four mineralization-related granite bodies (G1 to G4) were identified in the Dahutang mini...

This is a brief research report about the recently-discovered and currently being explored Dahutang tungsten deposit (or ore field) in northwestern Jiangxi, south-central China. The deposit is located south of the Middle–Lower Yangtze River valley Cu–Au–Mo–Fe porphyry–skarn belt (YRB). The mineralization is genetically associated with Cretaceous porphyritic biotite granite and fine-grained biotite granite and is mainly hosted within a Neoproterozoic biotite granodiorite batholith. The Dahutang o...

The porphyritic granite containing high tungsten content( typically several hundreds of × 10- 6) is discovered in the Dahutang area,Jiangxi Province,South China. The tungsten content is dozens to hundreds of times higher than the normal barren granites. In this paper,we reported detailed studies on the LA-ICP-MS zircon U-Pb dating,major elements,trace elements,zircon Hf isotopic compositions and whole-rock Nd isotopic compositions of the tungsten-bearing porphyritic granite. The studies of petro...

Abstract The Xuejiping porphyry copper deposit is located in northwestern Yunnan Province, China. Tectonically, it lies in the southern part of the Triassic Yidun island arc. The copper mineralization is mainly hosted in quartz-dioritic and quartz-monzonitic porphyries which intruded into clastic-volcanic rocks of the Late Triassic Tumugou Formation. There are several alteration zones including potassic, strong silicific and phyllic, argillic, and propylitic alteration zones from inner to outer ...

Abstract The Dongyuan deposit, in the recently identified world-class porphyry–skarn W metallogenic belt, east Jiangnan Orogen, China, is characterized by a set of nearly parallel and horizontal multi-cycle orebodies within cupolas of porphyritic granodiorite. Almost every orebody from the top to the bottom shows similar vertical changes in vein morphology and mineral assemblage from ≤1 cm quartz–feldspar–scheelite–calcite veins to 1–2 cm quartz–feldspar–muscovite–scheelite veins to 2–5 cm quart...

Abstract South China hosts many Nb–Ta deposits that show evidence for episodic mineralization, which were generated during the emplacement of composite granites. To constrain the spatio-temporal distribution of Nb–Ta mineralisation in the region and to identify future targets for mineral exploration, we used in situ laser ablation-inductively coupled plasma-mass spectroscopy to date 23 columbite-tantalite group mineral (CGM) samples from 14 Nb–Ta deposits. Our CGM U–Pb data, supplemented by prev...

Abstract The world-class Dahutang tungsten deposit is located within the Jiuling mining district of the central Jiangnan orogenic belt, Jiangxi Province, China. The deposit consists of a massive and gently dipping scheelite orebody that contains disseminated and veinlet-hosted mineralization located within a medium- to coarse-grained biotite granodiorite. The No. 1 ore block of the deposit also contains a 1.50–1.75 m thick shell-shaped pegmatoid zone that defines an inner contact zone between th...

The newly discovered Shimensi deposit is a super-large tungsten-copper (W–Cu) deposit with a metal reserve of 742.55 thousand tonnes (kt) W and 403.6 kt Cu. The orebodies are hosted in Mesozoic granites, which intruded the poorly documented Shimensi granodiorite belonging to the Jiuling batholith, the largest intrusion (outcrop > 2500 km2) in South China. Our new SHRIMP (Sensitive High Resolution Ion MicroProbe) zircon dating revealed that the granodiorite at Shimensi (ca. 830–827 Ma) was formed...

Abstract The newly discovered giant Dahutang W–Cu–Mo deposit in the central part of the Jiangnan Orogen hosts an estimated resource of 1.1 million tons (Mt) of WO 3 , plus a proven resource of 0.65 Mt Cu and 0.08 Mt Mo. The Dahutang deposit is temporally and spatially associated with the Late Mesozoic S-type granites emplaced into the Neoproterozoic Jiuling granodiorite batholith and the Shuangqiaoshan Group. Based on petrographic observations, eight hydrothermal alteration/mineralization stages...
