The Lower Yangtze river belt is one of the most important metallogenic belts in China. mechanisms responsible for ore genesis and formation related Cretaceous igneous rocks, such as adakite, A-type granitoid, Nb-enriched basalt, remain controversial. Mesozoic granitoids were mostly formed Early (140–125 Ma), three granitoid belts—the inner, south, north—have been defined according to petrological geochemical characteristics. Previously, based mainly on negative eNd high initial Sr isotope...
Abstract Although deep carbon recycling plays an important role in the atmospheric CO2 budget and climate changes through geological time, precise mechanisms remain poorly understood. Since recycled sedimentary carbonate plate subduction is main light-δ26Mg reservoir within deep-Earth, Mg isotope variation mantle-derived melts provides a novel perspective when investigating cycling. Here, we show that Late Cretaceous Cenozoic continental basalts from 13 regions covering whole of eastern...
Adakites may form by partial melting of either the subducting oceanic lithosphere or lower part continental crust. These two magma types can be discriminated geochemically using a combination La/Yb, Sr/Y ratios, MgO and Na2O contents, Sr–Nd isotopes. Given that basaltic crust has Cu concentrations more than times higher mantle wedge, 'primitive' adakites produced slab should contain significantly contents derived from crust, as well normal arc andesites. A globally compiled dataset shows in...
SE China is well known for its Mesozoic large-scale granitoid plutons and ore deposits. In China, igneous rocks with intrusion ages between 180 125 Ma generally become progressively younger towards the NE. More specifically, 180–160 are distributed throughout a broad area, mineralization ranging from Cu–Au Pb–Zn–Ag to W–Sn; 160–150 present mainly in Nanling region associated W–Sn mineralization; occur NE area that has many fewer These can be plausibly interpreted as reflecting southwestward...
Rare Earth Elements (REE) are essential to modern society but the origins of many large REE deposits remain unclear. The U-Th-Pb ages, chemical compositions and C, O Mg isotopic Bayan Obo, world's largest deposit, indicate a protracted mineralisation history with unusual features. Coexisting calcite dolomite in isotope disequilibrium; some calcitic carbonatite samples show highly varied δ26Mg which increases increasing Si Mg; ankerite crystals decreases Fe from rim centre, patterns. These...
The petrogenesis of adakites holds important clues to the formation continental crust and copper ± gold porphyry mineralization. However, it remains highly debated as whether form by slab melting, partial melting lower crust, or fractional crystallization normal arc magmas. Here, we show that adakitic signature, a subducting oceanic would require high pressure at depths >50 km, whereas presence plagioclase thus shallower additional water. These two types can be discriminated using...
The Dexing porphyry Cu deposit is the largest in eastern China, with total reserves of 8.4 Mt Cu. porphyries have geochemical characteristics typical adakites: they are similar to examples Circum-Pacific Belt and Lower Yangtze River but different from adakites Dabie Mountains Tibetan Plateau. Ce4+/Ce3+ values calculated zircon trace-element compositions vary 495 1922 0.51 0.82, respectively, reflect high oxygen fugacity that measured or inferred for Cu-Au deposits South America. consistent...
The Tongling district is one of the most important non‐ferrous metal producers in China. origin Cu–Au deposits region closely related to Late Mesozoic intermediate intrusions, which are mainly high‐K calc‐alkaline and shoshonitic series. Geochemical characteristics indicate that these granitic rocks mixtures more than two compositional end‐members, i.e. mantle‐derived melts crust components incorporated through assimilation. Three magmatic intrusions – Jiguanshi quartz monzodiorite,...
The destruction of the North China Craton (NCC) mainly occurred in Cretaceous and has been attributed to a "top-down" rapid delamination, "bottom-up" long-term thermal/chemical erosions, or hydration by subduction-released fluids. On basis distribution one Jurassic two Early adakite belts drifting history paleo-Pacific Plate, we propose that three ridge subduction events dominated large-scale decratonization NCC. Both physical erosion magmatism induced contributed NCC; last subduction, at...
The Early Cretaceous Huangmeijian Pluton is an A-type granite located on the northern bank of Lower Yangtze River in Anhui Province, east-central China. It intruded SE edge Luzong volcanic basin. moderate- to coarse-grained mainly composed alkali feldspar, plagioclase, and quartz has a typical geochemical signature. LA-ICP-MS zircon dating yielded weighted mean 206Pb/238U age 127.1 ± 1.4 Ma, similar other granites belt, indicating extensional environment. Temperatures calculated using...
Abstract Orogenic gold (Au) deposits are the most important type, accounting for more than half of world's proven Au reserves. They mainly controlled by three key factors: (1) abundant andesitic rocks (SiO2 55–60 wt.%) at depth, which have systematically higher contents other rock types; (2) a pervasive transition from greenschist facies to amphibolite metamorphism within short period, releases S2−-rich fluids that may scavenge host rocks; and (3) deformation fracturing under...
The Nanling range (Nanling) is characterized by intense and widespread Mesozoic magmatism related large-scale W–Sn mineralization. A summary of geochemistry, geochronology, petrogenesis for the W–Sn-bearing granites has been carried out in this study. series rock- ore-forming ages indicate that mineralization closely to Early Yanshanian granitic both temporal spatial dimensions (165–150 Ma). Geochemical features show W- Sn-bearing granites, which mainly belong highly fractionated I-type with...
