Geochemical signatures throughout the layered Earth require significant mass transfer through the lower crust, yet geological pathways are under-recognized. Elongate bodies of basic to ultrabasic rocks are ubiquitous in exposures of the lower crust. Ultrabasic hornblendite bodies hosted within granulite facies gabbroic gneiss of the Pembroke Valley, Fiordland, New Zealand, are typical occurrenc...

Eoarchean [3.6 to 4.0 billion years ago (Ga)] tonalite-trondhjemite-granodiorite (TTG) is the major component of Earth's oldest remnant continental crust, thereby holding the key to understanding how continental crust originated and when plate tectonics started in the early Earth. TTGs are mostly generated by partial melting of hydrated mafic rocks at different depths, but whether this requires...

Porous asphalt (PA) pavements are widely employed in areas with wet climates. As particle enhancement inclusions mastic, mineral fillers play essential roles improving the performance of PA pavements. This study developed a coupled multiscale finite element (FE) model, involving mesostructure mixture and pavement. Four types mastic properties were four (Granodiorite, Limestone, Dolomite, Rhyoli...

The Ahetala granodiorite is located in the western section of South Tianshan Orogenic Belt (STOB), which great significance regarding dispute on closing date Ocean (STO) and tectonic evolution STOB. To determine setting petrogenesis, study petrography, electron probe microanalysis (EPMA), LA-ICP-MS zircon U–Pb geochronology, major trace elements analyses are carried out for granodiorite. Based ...
