(1) Background: The widely developed thrust structures in the Jingzhushan Formation of late Cretaceous Nyima Basin are related to collision which leads orogeny between Lhasa and Qiangtang blocks. Clarifying tectonic properties is great significance characterize evolution block block. (2) Methods: Combined with mineralogy petrology U-Pb zircon dating extrusive rocks, a detailed magnetic fabric t...

The emplacement of Large Igneous Provinces (LIPs) throughout the Phanerozoic Eon introduced vast quantities mafic rocks to Earth's surface, which were subsequently weathered into oceans. Osmium isotope data can be used track these LIP-related weathering fluxes, providing a global fingerprint timing and magnitude LIP emplacement, guiding assessments impact events on ocean biogeochemistry regulat...

Integration of seismic, gravity and magnetic data revealed variations in crustal architecture along the Yucatan passive continental margin. The crust beneath salt basin is ~10 km thick primarily a lower crust. In contrast, Campeche thicker comprises both upper layers. These explain strikingly different tectonic histories these basins outlined by previous authors. rifting margin was associated w...

The mainly deep-submarine Ontong Java Plateau (OJP) is the result of largest outpouring lava in geologic record. Volcanic events this magnitude can have dramatic environmental impacts due to volatile emissions. We report new S measurements naturally glassy, olivine-hosted melt inclusions and pillow basalt glasses from OJP. combined these data with previous OJP quantify degassing a suite glasses...

Prediction of drug target interaction is an extrusive domain discovery and repositioning drugs. Most conventional studies are carried out in early years the wet laboratory, but it very expensive time consuming. So nowadays, use machine learning techniques to predict pairs. A new method targeting drugs introduced this paper. Use Pseudo Position Specific Scoring Matrix (PsePSSM) used represent ta...

Drilling a complete section of oceanic crust has been an unfulfilled ambition since the inception of scientific ocean drilling. Recovery of in situ oceanic crust is imperative to understand igneous accretion and the complex interplay between magmatic, hydrothermal, and tectonic processes, as well as a means for calibrating remote geophysical observations, particularly seismic and magnetic data....

Abstract We used a large set of satellite- (visible, infrared, and radar images from Planetscope, MODIS, VIIRS, Sentinel2, Landsat 8, Sentinel 1) ground-based data (optical images, SO 2 flux, shallow seismicity) to describe characterize the activity Sabancaya volcano during unrest eruption phases that occurred between 2012 2020. The phase (2012–2016) was characterized by increasing gas thermal ...

Volatile emissions to the atmosphere associated with Siberian Traps eruptions at Permian-Triassic boundary were sourced from outgassing of primary magmas and sedimentary host rocks into which they intruded. Halogens in volcanic gases may have played an important role environmental degradation stratospheric ozone destruction. Here we investigate how halogens behave during interaction between sal...

The Demerara and Guinea plateaus are conjugate Transform Marginal Plateaus (TMPs) formed at the junction of Jurassic Central Atlantic Ocean Cretaceous Equatorial Ocean. We compare their structure evolution through a combined industrial/academic seismic dataset tied by well data. show that these TMPs record complete history from to breakup seafloor spreading phases. Both first as volcanic margin...
