The Rio Jacaré Batholith (RJB; 617 ± 4 Ma) is inserted in the Poço Redondo Domain, Sergipano Orogenic System. This batholith formed by monzodiorite, quartz monzonite, and with abundant microgranular enclaves (MEs). MEs vary from black to light gray exhibit globular slightly elongated shapes clear-cut, crenulated, cuspate, or, more rarely, diffuse contacts. They correspond diorites, monzodiorite...

The characterisation of quartz grains’ chemical and mineralogical properties in sediments sedimentary rocks is widely used provenance studies. This paper analyses grains from the coarse sand fraction soils Quaternary fluvial terraces (Guadalquivir River, southern Spain). tentative soil ages are 0.3 ka (Haplic Fluvisol), 7 Calcisol), 70 (Cutanic Luvisol), 300 (Lixic Calcisol) 600 Luvisol). shed ...

Abstract Detrital K-feldspar 40Ar/39Ar thermochronology was conducted on clastic sedimentary rock samples collected from northern exposures of the Upper Cretaceous Nanaimo Group Vancouver Island and adjacent Gulf Islands British Columbia to constrain denudation history local Coast Mountains batholith source region determine origin extraregional sediment supplied basin.

South China is a well-known grand felsic igneous rocks province. However, it still controversial and not well understood whether the Mesozoic tectono-magmatic pattern dominated by subduction of paleo-Pacific oceanic plate. In this study, we address question concentrating on long-term evolutionary Guandimiao batholith, which has complex lithofacies with different formation ages can be superb rec...

The monzogranites and syenogranites of the Early Devonian (Emsian), post-tectonic, high-level, S-type Wilsons Promontory batholith contain magmatic garnet cordierite, in addition to biotite, as well biotite–quartz pseudomorphs after early orthopyroxene. forms southern tip Australian mainland consists four penecontemporaneous plutons, emplaced at shallow crustal depth, intruding Ordovician Lower...

Thermobarometric and Os isotopic data for peridotite xenoliths from late Miocene and younger lavas in the Sierra Nevada reveal that the lithospheric mantle is vertically stratified: the shallowest portions (<45 to 60 kilometers) are cold (670 degrees to 740 degrees C) and show evidence for heating and yield Proterozoic Os model ages, whereas the deeper portions (45 to 100 kilometers) yield Phan...
