The Tongling ore district of the Middle-Lower Yangtze metallogenic belt is a famous Cu-Au-Fe-S polymetal region, and its tectonic deformation, magmatic evolution, processes have been studied for decades. In this article, we propose comprehensive tectonic-magmatic-metallogenic model ore-forming mechanism constrained by magmatism regional deformation. district, regime underwent two transitions. (1) Middle Triassic, transitioned from quiescence to intense compression. During contraction,...
Cassiterite (SnO2) is the main ore mineral of tin in magmatic–hydrothermal deposits, but transport and precipitation mechanisms from hydrothermal fluids remain poorly understood. We critically evaluated aqueous speciation extensive experimental data thermodynamic modeling. Sn(II) chloride complexes exist mainly as SnCl+, SnCl2(aq), SnCl3−. The revised Helgeson–Kirkham–Flowers model parameters these three species two ions (Sn4+ Sn2+) were derived correlation algorithms among parameters,...
The accurate in situ U–Pb age of scheelite can be determined using our proposed methods normal ablation settings via LA-SF-ICP-MS.
The nature and origin of the early Yanshanian granitoids, widespread in South China Block, shed light on their geodynamic setting; however, understanding magmatism processes remains a challenge. In this paper, we present both major trace elements bulk rock, Sr–Nd–Pb isotopic geochemistry, zircon U–Pb–Hf isotopes low Sr high Yb A2-type granites, which were investigated with aim to further constrain petrogenesis tectonic implications. Zircon U–Pb dating indicates that these granites emplaced...
The Danchi fold-and-thrust belt, Guangxi, South China, contains the Mangchang, Dachang, and Wuxu large giant Sn-polymetallic districts. It hosts more than 1.2 Mt of ore grading 1 % Sn, 6.23 Zn at 2.4 %, 1.13 Sb 1.3 %. district is one Sb-Zn dominated hydrothermal districts without magmatic rocks exposing in south belt. Recent drilling exploring mining have identified a partially Sn mineralization associated with Zn-Sb mineralization. These works provide an opportunity to evaluate potential...
The Tongling region, an important Cu + Au ore district, consists of a series S-folds and is defined by irregular set boundaries. regional structural framework was traditionally considered to be the result coaxial compression, followed simple shear. By analysing spatial distribution fold geometries fault densities, we propose new deformation model. Two tectonic stages, that is, early NW–SE later NE–SW have been newly identified in this region. In stage, shortening produced collision between...
This study presents rock slab and thin section reflection mapping, element mapping by Micro-XRF (μ-XRF) analysis, in situ cassiterite U-Pb laser ablation-inductively coupled plasma mass spectrometer (LA-ICP-MS) ages of the Xinlu Sn-Zn deposit, Nanling Sn-W belt, South China. The new results provided constraints on age processes Sn mineralization thus further discussed role Paleo-Pacific plate formation belt. Based mineralogy μ-XRF four episodes are distinguished Baimianshan segment,...
Abstract: The Tengchong geothermal area, an active tectonic region with frequent earthquakes, is located in Yunnan Province of southwestern China. This area contains abundant hot springs, which often display high metal concentrations and obvious mineralization phenomena. At 19:19 on 9 July 2009, earthquake occurred Yao'an, Chuxiong, Province, 300 km to the northeast area. We sampled water springs from 4 2009 10 15 study changes elemental before after discuss influence springs. most trace...
The South China block (SCB) experienced the tectonic transition from Paleo-Tethys to Paleo-Pacific domains during Mesozoic, but process is hotly debated. Youjiang fold-and-thrust belt (YFTB), in interior of Basin southwestern SCB, located a junction these two and thus witnessed their evolution. It also separates northern thin-skinned structures southern thick-skinned basin. Therefore, YFTB an intriguing window into Mesozoic evolution SCB SCB. In this study, we conduct structural analysis at...
