Abstract
Abstract Evaporites have played important role in the formation of diverse metallic ore deposits, especially in the case of magmatic–hydrothermal deposits. However, the relationship between evaporites and skarn Fe deposit remains poorly constrained. In this contribution, we present new sulfur isotope data of pyrite, as well as the composition of halogen-rich minerals (scapolite and amphibole) in the Jinshandian skarn Fe deposit. The data are used to evaluate the evidence for incursion of evaporites in the skarn Fe deposit. The δ 34 S values for pyrite from the early and late retrograde stage range from +17.4‰ to +18.7‰ ( n  = 4) and +16.4‰ to +19.4‰ ( n  = 13), respectively. Both these values are markedly heavier than the common δ 34 S values of sulfides from magmatic–hydrothermal fluid, indicating that sulfur in the Jinshandian ore-forming system was mostly derived from evaporites. Compared to the amphibole from endoskarn, the scapolite and amphibole from exoskarn show high Cl content up to 4.04% and 3.01%, respectively, suggesting that the hydrothermal fluid with high NaCl content was probably derived from evaporites. The amphiboles from endoskarn are more enriched in F which is probably of magmatic in origin. The data presented in our study suggest that the hydrothermal system of the Jinshandian skarn Fe deposit probably experienced significant incursion of evaporites before or during the late prograde stage.

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-...

Abstract Numerous magnetite–apatite deposits occur in the Ningwu and Luzong sedimentary basins along the Middle and Lower Yangtze River, China. These deposits are located in the contact zone of (gabbro)-dioritic porphyries with surrounding volcanic or sedimentary rocks and are characterized by massive, vein and disseminated magnetite–apatite ± anhydrite mineralization associated with voluminous sodic–calcic alteration. Petrologic and microthermometric studies on multiphase inclusions in pre- to ...

Abstract China has a rich reserve of iron ores and hosts most of the major types of iron deposits recognized worldwide. However, among these, the banded iron formation (BIF), skarn, apatite–magnetite, volcanic-hosted, sedimentary hematite and magmatic Ti–Fe–(V) deposits constitute the most economically important types. High-grade iron ores (> 50% Fe) are relatively rare, and are mostly represented by the skarn-type. Most of the BIF deposits formed in the Neoarchean, with a peak at ~ 2.5 Ga, and ...

The magmatic-hydrothermal system-related iron deposits include magmatic V-Ti magnetite deposits,apatite-magnetite deposits,iron skarn deposits and submarine volcanic-hosted iron deposits. The ore-related igneous rocks have a wide spectrum,ranging from basic-ultrabasic,intermediate to intermediate-felsic rocks. The magmatic V-Ti magnetite deposit are associated with basicultrabasic plutonic intrusions. These deposits are formed during the magma evolution,particularly fractional crystallization. W...

U-Pb ages and trace element compositions of two types of hydrothermal titanite from the Jinshandian iron skarn deposit,southeastern Hubei Province,have been successfully analyzed by laser ablation inductively coupled plasma mass spectrometry( LAICPMS). Compared to titanite from diopside and scapolite skarn,hydrothermal titanite from albite altered quartz diorite are characterized by lower REE,δEu values,Th /U,Lu /Hf ratios and higher Hf component and LREE /HREE,suggesting they formed under diffe...

Abstract The Asian continent formed during the past 800 m.y. during late Neoproterozoic through Jurassic closure of the Tethyan ocean basins, followed by late Mesozoic circum-Pacific and Cenozoic Himalayan orogenies. The oldest gold deposits in Asia reflect accretionary events along the margins of the Siberia, Kazakhstan, North China, Tarim–Karakum, South China, and Indochina Precambrian blocks while they were isolated within the Paleotethys and surrounding Panthalassa Oceans. Orogenic gold depo...

The Middle-Lower Yangtze Polymetallic Ore Belt is one of the most important metallogenic belts in East China,comprising more than 200 polymetallic( Cu-Fe-Au,Mo,Zn,Pb,Ag) deposits. Ningwu and Luzong ore distrcts are the most important component of this belt. In these districts,volcanic-subvolcanic rocks,intrusions and subvolcanic rocks-related iron deposits which are well known as porphyrite iron deposits in China are widespread,during the Late Mesozoic. Based on the geological characteristics,sp...

Abstract Although the sources of the ore metals remain problematic in most Iron-oxide Cu and Au (IOCG) deposits, external sulphur, either from surficial basinal brines and seawater (e.g., Central Andean and Carajas deposits) or from formation water and metamorphic fluids (e.g., the Cloncurry deposits), or introduced by magmatic assimilation of metasedimentary units (e.g., Phalaborwa), has been documented in many major Cu-rich IOCG centres. However, only the evaporite-sourced fluids yield diagnos...

Abstract The Fujiashan-Longjiaoshan deposit is located in the southern area of the Edong District of the Middle-Lower Yangtze River metallogenic belt. W-Cu-(Mo) orebodies are found in the contact zone between the granodiorite porphyry and Carboniferous to Triassic carbonate strata. Four stages of ore formation are identified: (1) the prograde skarn stage, (2) retrograde skarn stage, (3) quartz-sulfide stage (further subdivided into the early 3a and later 3b), and (4) carbonate stage. In this stu...

The Huanggangliang deposit is a super-large Sn-Fe deposit in the Huanggangliang–Ganzhuermiao metallogenic belt in the southern section of the Great Hinggan Range. The Sn-Fe deposits mainly occur in the skarn contact zone and were formed via the interaction of biotite-bearing alkali feldspar granite with limestone strata of the Permian Dashizhai and Zhesi Formations. Based on the intersecting relations among the ore-bearing veins and the different types of mineral assemblages within these veins, ...

Abstract This paper reports whole-rock geochemical, zircon U–Pb and Hf isotopic data for ore-hosted granitic gneisses, mineral compositions of oxides, and sulfur isotopic data for sulfides in iron ores from the Tianhu deposit, central part of the Eastern Tianshan. Our results can provide crucial constraints on the genesis of granitic gneisses and early Paleozoic tectonic setting of the Eastern Tianshan. LA-ICP-MS U–Pb dating on magmatic zircons yielded weighted mean 206 Pb/ 238 U ages of 463 to ...

Abstract The Jinshandian ore field represents one of the largest concentrations of Fe skarn deposits in the Edong district of Eastern China. Orebodies of these deposits occur in skarn along the contacts between quartz diorite or quartz monzonite and Triassic sedimentary country rocks. In this paper, we present new U–Pb geochronological data for magmatic zircon and hydrothermal titanite, as well as 40 Ar/ 39 Ar ages on hydrothermal phlogopite, to determine whether multiple magmatic-hydrothermal e...

Abstract The Heijianshan Fe–Cu (− Au) deposit is located in the Aqishan–Yamansu belt in Eastern Tianshan, NW China. As a typical Fe–Cu deposit in the region, Heijianshan is hosted in the Upper Carboniferous Matoutan Formation submarine volcanic/volcaniclastic rocks. Alteration styles, mineral assemblages and vein crosscutting relationships divide the hydrothermal alteration and mineralization processes into seven stages, namely the chromite (Stage I), epidote (Stage II), magnetite (Stage III), p...

Abstract Cu and Fe skarns are two economically important types of skarn deposit worldwide, but the critical factors controlling the difference in metal associations remain enigmatic. The Edong ore district, China, presents an excellent opportunity to study the differences between Cu–Fe and Fe skarn deposits. We have measured He–Ar isotopes trapped in fluid released by crushing pyrite and chalcopyrite from four well known Cu–Fe and Fe deposits in the Edong district, Eastern China, with the aim of...
