Abstract Active layer dynamics are basic information for understanding permafrost degradation, but there gaps in our knowledge of the active thickness (ALT) variations during past two decades and their future changes; this is especially true data with high spatial resolution. Here, based on monitoring ERA5 (the 5th generation reanalysis project from European Centre Medium‐Range Weather Forecasts)‐Land temperature data, we simulated changes ALT Northern Hemisphere 2000–2018 at a resolution 1...
In recent decades, phytoplankton proliferation and sediment input to rivers (especially urban rivers) have become more dramatic under the compound pressure of climate change human activities. Given generally narrow width current high spatial resolution satellites, which are limited by band settings, bandwidth, signal-to-noise ratio, UAVs with their exceptional spatiotemporal can be used as a useful tool for river environmental monitoring inversion uncertainty assessment. this study,...
Land cover classification is of great value and can be widely used in many fields. Earlier land methods traditional image segmentation techniques, which cannot fully comprehensively extract the ground information remote sensing images. Therefore, it necessary to integrate advanced techniques deep learning into study semantic However, most current high-resolution networks have disadvantages such as large parameters high network training cost. In view problems above, a lightweight model via...
With the continuous development and popularization of remote sensing technology, images have been widely used in field land cover classification. Since complex spatial structure texture features, it is becoming a challenging problem to accurately categorize them. Land classification has practical application value various fields, such as environmental monitoring protection, urban rural planning management, climate change research. In recent years, image methods based on deep learning rapidly...
The Lalingzaohuo cobalt-bearing Cu polymetallic skarn deposit, located in the central part of East Kunlun Orogenic Belt, is mainly hosted Paleoproterozoic Jinshuikou Group. occurrence and genesis cobalt at were investigated by field geology, mineralogy, geochronology, electron probe microanalyses (EPMA), that these data provide some insights into ore-forming process also show key characteristics a skarn. Garnet U-Pb dating yielded lower intercept 206Pb/238U date 207.5 ± 4.9 Ma, younger than...
The early Paleozoic Wuyi-Yunkai orogeny involves voluminous magmatism and represents the first major tectonothermal event in South China block since Neoproterozoic break-up of Rodinia supercontinent. Here we investigate three representative granitic plutons Guangxi province southwest with a view to understand magmatic response orogeny. We present results trace elements, Sr-Nd isotopes, zircon U-Pb ages Hf isotope. LA-ICPMS geochronology reveals that these emplaced during Silurian (441–432...
The evolution of the Palaeo-Tethys Ocean played an important role in Palaeozoic tectono-metallogenesis Southeast Asia, which diverse blocks amalgamated due to its closure. Previous researches focused mostly on endogenic metallogenesis related Ocean. However, tectonic control numerous Mn ore deposits southwestern South China Block (SCB) developed during is largely unknown. In this article, we review and define four evolutionary stages from initial opening, maturity, incipient subduction,...
Major Sn deposits are commonly linked to crust-derived and highly evolved granites, with magma generation aided by mantle heating. However, whether how the components contribute polymetallic mineralization remains unclear. In this study, in combination a compilation of equivalent data region, we provide new constraints on issue based detailed investigations petrogenesis metallogenic significance granitoids including causative batholith later granodiorite porphyry dike giant Dachang deposit...
To detect the exhumation history of southwestern South China Block (SCB), we performed fission track (FT) analysis on zircon and apatite grains in granitoid sedimentary samples. From east to west, study area includes Yunkai Massif, Lingshan granitic belt, Shiwandashan Basin, eastern margin Youjiang Basin. The granite sample Massif has two peaks 75 92 Ma for FT dating. belt samples yield central ages from 135 132 Ma. Permian bauxite Basin 109 93 display age at ~97–93 74 104 dating, while 81...
A single sand body is defined as a geological unit that continuous vertically and horizontally but separated from the upper lower bodies by mudstone or impermeable intercalation. The architecture of significant in determination hydrocarbon accumulation mechanisms gas reservoirs, especially for exploitation multiple tight sandstone (TSG) reservoirs. One such example reservoirs Tianhuan Depression, China, where genesis are poorly understood. Based on geologic background sedimentary...
To constrain the relationship between plate boundary dynamics and basin sedimentation in southwestern South China Block (SCB), we undertook detrital zircon U–Pb–Hf isotope compositions of Lower‐Middle Triassic turbidite system Youjiang Basin biotite 40 Ar/ 39 Ar thermochronology adjacent Lingshan granite. The zircons from Lower clastic rocks are dominated by age peaks at ~450 Ma ~1,000 minor ~250–260 with negative ε Hf (t) values (−6.4 to −10.1). In contrast, Middle group contains more...
The Tuolugou sedimentary-exhalative (SEDEX) Co-Au deposit is located in the eastern Kunlun metallogenic belt of northern Qinghai-Tibet Plateau China. Pyrite prevalent Co-hosting sulfide mineral that occurs deposit. In this study, we investigated characteristics Co-bearing pyrite and effect Co on crystal structure to obtain a better understanding mineralization. Three generations were identified, including Co-barren (Py-1, formed during early mineralization stage I, with content 1-3844 ppm),...
