In this study, the authors aimed to compute lithospheric thickness beneath North China Craton (NCC) by combining measurement of thermophysical properties lherzolite xenoliths from Cenozoic basalts in with corresponding geothermal data, thus providing constraints for thinning NCC. Based on precise thermal diffusivity, specific heat capacity at high temperatures, and density room temperature lherzolites NCC, dependence lattice conductivity was obtained. Combining surface flow, production rocks...
The speckle noise inherent in synthetic aperture radar (SAR) imaging has long posed a challenge for SAR data processing, significantly affecting image interpretation and recognition. Recently, deep learning-based removal algorithms have shown promising results. However, most existing rely on convolutional neural networks (CNN), which may struggle to effectively capture global information lead texture loss. Besides, due the different characteristics of optical images images, results training...
Most approaches for image retrieval are based on the bag-of-visual-word (BoV) representation. However, BoV model typically ignores spatial information that is crucial visual Zhang, et al. [1] proposed an approach to encode into Bo V using Geometry-preserving Visual Phrases (GVP). They found 2-GVP gives best results in general, while performance of high order GVP (length>; 2) decreases because it encodes too much constraint. Although performs worse can often generate a better top 10 retrieved...
Abstract Felsic gneiss is a major type of ultrahigh-pressure metamorphic rock in continental subduction zones. As an important mineral felsic gneiss, the phase behavior K-feldspar great significance for studying subducting seismic activities, crust-mantle interactions, and plate tectonics Earth’s interior. In this study, we investigated relations using Raman spectroscopy combined with externally heating diamond-anvil cell (DAC) under high-pressure (28 GPa), high-temperature (400 °C),...
Abstract Capsule sealing has always been a key procedure in hydrothermal experiments to explore the composition and properties of geo-fluids their influence on various geological processes. Previously reported capsule techniques have primarily focused either weld-sealing or cold-sealing methods, which some disadvantages limitations. Here, we report newly developed, simple, effective technique incorporating operations from techniques. The includes three steps: first, preparing inner outer...
Abstract Many metal deposits were formed by carbonic fluids (rich in CO 2 ) as indicated fluid inclusions minerals, but the precise role of mineralization remains unclear. The main components inclusions, i.e. H O and , correspond to decomposed products organic acids, which lead us consider that process acids transport then discharge metals when they are stable unstable, respectively. Here we show thermal stability copper acetate solution at 15–350 °C (0.1–830 MPa) provides insight transport....
