The Meso- to Neoproterozoic magmatic rocks cropping out in the western Yangtze Block are pivotal comprehending tectonic-magmatic revolutionary processes of South China Craton during breakup and assembly Rodinia. A combined study including a detailed geological survey, systemic measurement section, petrographic observations, geochronology, elemental geochemistry was carried on southern margin Paoma granitic pluton SW China. obtained data major elements, along with mineralogy that includes...
Preserved numerous intermediate to acid igneous rocks with minor basic ultrabasic rocks, the Western Yangtze Block (WYB) is window see evolutional process of South China Craton during Precambrian era. Here, we report geochronology and geochemistry data from gabbros in south Dechang County SW Sichuan Province. Field investigation zircon U–Pb age a gabbro sample suggest that these mafic were emplaced early Neoproterozoic era (831.8 ± 2.6 Ma). These show low contents SiO2, K2O, Na2O. They are...
An N-S trending Neoproterozoic magmatic belt is preserved along the western margin of Yangtze Block, which characterized by predominant felsic and minor mafic-ultramafic rocks. However, four geodynamic models have been proposed to elucidate formation these In this paper, we present geochronological geochemical data for dacite crystal tuff, rhyolitic welded rhyolite from Suxiong Formation. These findings, combined with previously published Sm-Nd isotopic data, aim provide robust constraints...
Abstract In the western Yangtze Block, widespread Mesoproterozoic to Neoproterozoic rocks are key understanding Precambrian tectonic‐magmatic evolution of region. However, their petrogenesis and tectonic setting still controversial. this paper, zircon U‐Pb ages, Sm‐Nd isotopic whole‐rock geochemical data reported from selected fresh samples in southern Dechang county, southwestern China, order constrain emplacement age magma source, as well setting. They mainly composed biotite monzogranite,...
The triaxial cyclic loading and unloading test was carried out on a TAW‐2000 rock mechanics to study the permeability characteristics of deep‐buried sandstone. This paper analyzed evolution laws permeability, elastic modulus, damage, dissipated energy, acoustic emission events sandstone under different confining pressures. It also introduced concept relative strain further discussed relationship between permeability. results showed that obviously experienced three stages. At low level,...
On August 8, 2017, an earthquake of magnitude 7.0 on the Richter scale occurred in Jiuzhaigou, Sichuan, causing significant damage to both life and property. Traditional geological hazard investigation is difficult Jiuzhaigou because high altitude, high‐altitude canyons, vegetation‐covered seismic areas. This study explores technical advantages using airborne LiDAR technology penetrate vegetation gather information directly from surface, rapidly acquiring 3D point cloud data Through...
Abstract Numerous Neoproterozoic granitic intrusions occur over a north-south distance of more than 700 km in western Yangtze Block. In this paper, we newly identified Shimian pluton as A-type granite which was previously considered S-type the region, with presenting its zircon U-Pb age, Lu-Hf isotopic and whole-rock geochemical data. The selected fresh samples for study are mainly porphyritic biotite monzogranites. They weak peraluminous, A 2 -subtype granites, displaying high contents SiO...
Abstract This paper describes the Baibao landslide that occurred in October 2017 within a Jurassic formation Guojiaba town, Zigui County, Yichang city, China. The factors leading to this include complex geological conditions, slide-prone strata, and fluctuating water level of Three Gorges Reservoir. Borehole field investigations indicate can be divided into two parts: medium deep rock partial soil sliding landslide. A comprehensive analysis monitoring data, including GPS, precipitation,...
