A sandy braided river is a vital terrestrial sedimentary system. However, due to its reservoir’s substantial heterogeneity, the sand body’s spatial stacking pattern and distribution are complex, making it challenging to establish a highly reliable 3D geological model of the braided river reservoir [].Academics have extensively studied modeling …Key Laboratory of Mineralogy and Metallogeny, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, ChinaThe 6 February 2023 M w 7.8 Pazarcık and subsequent M w 7.5 Elbistan earthquakes generated strong ground shaking that resulted in catastrophic human and economic loss across south‐central Türkiye and northwest Syria. The rapid characterization of the earthquakes, including their location, size, fault geometries, and slip kinematics, is …

On 9 April 2000, a 91 Mm 3 rock avalanche occurred in Linzhi Prefecture, Tibet. The event was accompanied by a deafening noise, with the rock mass travelling from a maximum elevation of 5132 m and coming to a rest at an elevation of 2163 m.The extracted heavy-mineral concentrates were sieved into four fractions: <0.1 mm, 0.1–0.25 mm, 0.25–0.5 mm, and >0.5 mm. Magnetic minerals from each fraction were separated using a very weak magnet. Since awaruite is more magnetic than magnetite, its proportion in the resulting concentrate was high.Browse Journals by Title | GeoScienceWorld Browse Journals by Title A AAPG Bulletin American Mineralogist B Bulletin de la Société Géologique de France Bulletin of Canadian Energy Geoscience Bulletin of Canadian Petroleum Geology Bulletin of the Seismological Society of America C Canadian Journal of Earth Sciences Canadian Journal of Mineralogy and Petrology Clay Minerals Clays and...

A machine-learning workflow to integrate high-resolution core-based facies into basin-scale stratigraphic models for the Wolfcamp and Third Bone Spring Sand, Delaware BasinCarbonatites, the most silica-poor igneous rocks, have a close relationship with rare earth element (REE) ore deposits, where low SiO 2 activity is considered to contribute to economic REE mineralization. However, a paradox is raised by quartz, commonly regarded as a Si-saturation proxy, which occurs in some giant carbonatites or … ….

Earthquake early warning (EEW) systems are crucial for mitigating seismic hazards. Current EEW algorithms predominantly rely on seismic data (Allen and Melgar, 2019) and can be classified into three main categories: point‐source, finite‐fault, and ground‐motion‐model based.Mar 17, 2023 · Chemical exchange between silicate magmas and carbonate rocks has major implications for igneous fractionation, atmospheric CO 2 flux, and formation of mineral deposits. . However, this process is only partly understood, and long-standing questions of whether, where, and how carbonate rocks can be digested by silicate melts remain controver We study the suitability of average peak ground acceleration (PGA) as a ground-motion proxy for parametric catastrophe bond (CAT bond) design. We tie the selection of PGA (as a tr
