Abstract Significant progress has been achieved in the research of tide-dominated environments past two decades. These studies highlight both importance and diversity tidal flats modern coastal environments. Based on their developing settings, are subdivided into nine types, which turn grouped sheltered or exposed spectrums according to magnitude exposure waves. The ternary classification model is revised with an embedded triangle non-open coast as major second-order morphological elements...
Abstract Volcanic regions commonly host swarms comprising small to moderate-sized earthquakes while tectonic faults mostly mainshock-aftershock sequences that can include very large earthquakes. In the southeastern Tibetan Plateau, formed by collision between Indian and Eurasian plates intersect with intraplate Tengchong volcanic field, seismic behavior of such an environment remains unclear. Here, we built a deep-learning-based high-precision earthquake catalog for field found (1) ~59%...
A full global geodynamical model over 600 million years (Ma) has been developed at the University of Lausanne during past 20 years. We show herein how 2D maps were converted into 3D (i.e., hypsometry and bathymetry), using a heuristic-based approach. Although synthetic topography may be viewed as relatively crude, it advantage being applicable anywhere on globe any geological time. The allows estimating sea-level changes throughout Phanerozoic, with possibility, for first time, to flood...
In North China, the Mesozoic terrestrial basins, sedimentary palaeogeography and tectonic settings involved five evolutionary stages: (1) Early‒Middle Triassic, (2) Late Triassic to Jurassic, (3) Jurassic early Early Cretaceous, (4) middle‒late Cretaceous (5) Cretaceous. The regional punctuated events occurred during these stages. During (stage 1), Xingmeng Orogenic Belt (XMOB, i.e., eastern part of Central Asia Belt, CAOB) northern China was settled in transition environment from...
Abstract On 21 May 2021, an M S 6.4 earthquake occurred in Yangbi, Yunnan province, China. A significant foreshock sequence 3 days before the mainshock, which provides opportunity to study nucleation. In this study, we adopt a template matching technique and double‐difference location method build catalog for of 2021 Yangbi earthquake, contains 1,086 events with high‐precision locations. The whole can be grouped into four episodes, each one W > 3.7 principal foreshock. foreshocks within...
During the last decades, numerous local reconstructions based on field geology were developed at University of Lausanne (UNIL). Team members UNIL participated in elaboration a 600 Ma to present global plate tectonic model deeply rooted geological data, controlled by geometric and kinematic constraints coherent with forces acting boundaries. In this paper, we compare values derived from (ages oceanic floor, production subduction rates, activity) combination chemical proxies (namely CO2,...
Chromium, a strategic mineral resource in China, is widely used high-precision equipment manufacturing. As the world's leading consumer and importer of chromite, China's external dependence exceeds 99%. The significant imbalance between domestic supply demand seriously threatens national economic security. This study discusses state chromium from four aspects: overview global resources, chromite production import volume, sources imported risk analysis. Considering industrial chain factors...
The modern Black Sea has a mixed upper layer in the top 150–200 m of water column, below which is anoxic, separated from by redox boundary. There limited vertical movement water. Pyrite framboids form column anoxic zone, then have been traditionally interpreted to sink immediately and accumulate sediments Sea. Thus occurrence rock record widely indicate poorly oxygenated conditions ancient environments. However, Permian–Triassic boundary (PTB) microbialites South China, formed shallow marine...
The resource potential, "fractured" reservoir, reservoir type and stimulation technology of Jurassic tight oil in central Sichuan basin were investigated. Based on the evaluation method resource, amount resources five layers estimated at 1.6 billion tons, showing that potential Basin is huge. Integrated analysis static dynamic data including core-description, thin section examination, well test exploration show reservoirs are fracture-pore with ultra-low porosity, super-low permeability,...
Identifying the source characteristics of silicic magmas (SiO2 >65 wt%) is significant for revealing nature crust and recycling processes under a continental arc zone. Herein, we present comprehensive dataset zircon U-Pb-Hf-O isotopes whole-rock major trace elements as well Nd two groups Neoproterozoic volcanic from Mianning area in western Yangtze block (South China), order to place systematic constraints on heterogeneous crustal sources reworking magmatic during evolution...
