Appinite suite rocks occur as small plutonic bodies, ranging from ultramafic to felsic in composition, that are characterized by abundant idiomorphic amphibole suggesting they the products of water-rich mafic magmas. Appinites also understood record tectono-magmatic processes during waning stages subduction convergent collisional tectonic settings. Measuring D/H and 18O/16O ratios hornblende ap...

Mantle wedge melting and the formation of hydrous mafic melts in collision orogenic belts have great significance for crustal related granitic magmatism, which can provide key messages about crustal–mantle interaction convergent margin. This paper reported Late-Triassic appinite (212 ± 2 Ma), is closely associated with granites. The large euhedral hornblende crystals indicate a water-rich featu...
Magmatic and tectonic processes can transport large volumes of magma generated in the deep crust as discrete pulses to shallower crustal depths, resulting incremental construction large, composite batholiths over thousands tens millions years. The Silurian Early Devonian Donegal batholith Ireland is a classic example which regional geological syntheses lithogeochemical data show that emplacemen...
The Datong pluton, the largest early Palaeozoic granitoid in the Western Kunlun Orogenic Belt (WKOB) in NW China, is a typical appinite-granite complex. It consists of diorites, quartz diorites, monzodiorites, quartz monzodiorites, monzonites, quartz monzonites, syenites, granodiorites and monzogranites. Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) zircon U–Pb dating ...
