Abstract The Tianshan in China forms the southern part of the Central Asian Orogenic Belt (CAOB) and also hosts important polymetallic resources. Here we investigate the Huangtupo medium–size copper–zinc deposit, located in the central part of the Kalatag copper Polymetallic Belt with a view to evaluate the nature and genesis of the early Paleozoic volcanogenic massive sulfide (VMS) Cu—Zn deposits. This deposit is correlated to intermediate–felsic volcano–sedimentary sequences of the early Paleo...

Abstract The East Junggar region links the Kazakhstan-Junggar plate with the Siberian Craton along the western part of the Central Asian Orogenic Belt. Among the major ore deposits in this region, the Xilekuduke molybdenite deposit is a unique example of Mo-dominated porphyry. Molybdenum and copper mineralization here occur as disseminated sulfides or veinlets mainly in granite porphyry and monzogranite, with a prominent alteration from an inner potassic, through sericitic to an outer propylitic...

The origin of the Zhaoanzhuang serpentine-magnetite deposit in the southern North China Craton (NCC) is highly disputed, with some investigators having proposed an ultramafic origin, whereas others favor a chemical sedimentary origin. These discrepancies are largely due to the difficulty in determining the protolithic characteristics of the highly metamorphosed rocks. Sulfur, magnesium, and boron isotope geochemistry combined with detailed petrography was carried out in this study to constrain t...

Abstract The South Tianshan Orogenic Belt (STOB) occupies the southwestern margin of the Central Asian Orogenic Belt (CAOB), and is the key region to understanding the Paleozoic evolution of the southern part of the Palo-Asian Ocean. Here we present an integrated study of zircon U Pb ages, whole-rock major and trace elements and Sr Nd isotopes on Silurian and Late Carboniferous intermediate-felsic intrusions exposed in the Oxidaban area located in the South Tianshan region in Xinjiang, NW China....

The origin of iron oxide-apatite deposits is controversial. Silicate liquid immiscibility and separation of an iron-rich melt has been invoked, but Fe–Ca–P-rich and Si-poor melts similar in composition to the ore have never been observed in natural or synthetic magmatic systems. Here we report experiments on intermediate magmas that develop liquid immiscibility at 100 MPa, 1000–1040 °C, and oxygen fugacity conditions (fO2) of ∆FMQ = 0.5–3.3 (FMQ = fayalite-magnetite-quartz equilibrium). Some of ...

Abstract Arc maturity is considered to play an important role in the mineralization of porphyry Cu—Au deposits. However, the early stage of arc is rarely preserved leading to controversies over arc evolution. Here we investigate gabbroic intrusions from the Akcha, Beleuti and Kalmakyr arc in relation to the Almalyk porphyry Cu—Au orefield in Uzbekistan. The Akcha biotite gabbro shows medium to fine grained texture, and is composed of plagioclase and biotite with minor clinopyroxene, orthopyroxen...

Abstract Continental crust can dramatically modify the geochemical and isotopic compositions (e.g., Sr-Nd, Pb) of mantle-derived lavas, and has important implications in understanding magmatic processes in continental arcs which involve subducted materials. In this paper, we report the Mg isotopic compositions of continental arc andesites from El Laco in northern Chile, and evaluate the contribution of the subducted slab to the formation of continental arc lavas. The andesites in the El Laco vol...
