Two‐Stage Mafic‐Felsic Magma Interactions and Related Magma Chamber Processes in the Arc Setting: An Example From the Enclave‐Bearing Calc‐Alkaline Plutons, Chinese Altai

Geochemistry, Geophysics, Geosystems, 2021
A systematic data set of petrography, mineralogy, geochronology, and geochemistry is reported for typical arc granitoids and associated mafic microgranular enclaves (MME) from the Chinese Altai, Central Asian Orogenic Belt.

Paired host-enclave geochemistry of mafic microgranular enclaves in the Eastern Belt granite, Peninsular Malaysia [PDF]

Bulletin of the Geological Society of Malaysia, 2007
This paper describes some of the important petrographic characteristics of the mafic microgranular enclaves and their host rock as well as their chemical relationship to selected granitic rocks from the Eastern Belt granite of Peninsular Malaysia. The enclaves are invariably darker coloured and finer grained than the enclosing granitic rocks.

Mineral and Whole-rock Geochemistry of the Kestanbol Granitoid (Ezine-Çanakkale) and its Mafic Microgranular Enclaves in Northwestern Anatolia: Evidence of Felsic and Mafic Magma Interaction

Turkish Journal of Earth Sciences, 2010
The Miocene Kestanbol granitoid, in Ezine-Çanakkale, Turkey, is one of post-collision granitoids of western Anatolia, which have been related to the the late Cretaceous collision between the Anatolide-Tauride platform and the Pontides. Magmatism began during the early Miocene, with coeval alkaline to calc-alkaline plutonism and volcanism, controlled by

Contribution from Mafic Melt to the Zhireken Porphyry Mo-Cu Deposit, Eastern Transbaikalia, Russia: Evidence from Mafic Microgranular Enclaves [PDF]

International Journal of Economic and Environment Geology, 2010
Mafic microgranular enclaves (MME) were formed in felsic ore-bearing porphyries from the Zhireken por-phyry Mo-Cu deposit, eastern Transbaikalia, Russia. Porphyry rocks were emplaced during the Upper Jurassic. Most of the enclaves are globular, oval-shaped and intermediate in composition (54% SiO2).

Magma mixing in the Karamaili granite belt of Eastern Junggar: evidence from A2-type granites and their mafic microgranular enclaves [PDF]

Frontiers in Earth Science
The Karamaili Orogenic Belt forms an essential part of the southernmost margin of the Eastern Junggar Orogenic Belt. The Late Carboniferous granitic belt of the Karamaili belt provides a valuable natural setting for studying the evolution of silicic magmas.

Interaction of the lithospheric mantle and crustal melts for the generation of the Horoz pluton (Niğde, Turkey): whole-rock geochemical and Sr–Nd–Pb isotopic evidence [PDF]

Estonian Journal of Earth Sciences, 2016
The Horoz pluton includes granitic and granodioritic rocks, with widespread mafic microgranular enclaves (MMEs). Petrochemically, the rocks of the pluton show calc-alkaline to shoshonitic and metaluminous to slightly peraluminous composition.

Petrogenesis of mafic microgranular enclaves (MMEs) in the oligocene-miocene granitoid plutons from northwest Anatolia, Turkey

Geochemistry, 2021
Abstract Mafic microgranular enclaves (MMEs) in host granitoids can provide important constraints on the deep magmatic processes. The Oligocene-Miocene granitoid plutons of the NW Anatolia contain abundant MMEs. This paper presents new hornblende Ar-Ar ages and whole-rock chemical and Sr-Nd isotope data of the MMEs from these granitic rocks ...

Petrogenesis of the Morobe Granodiorite and their shoshonitic mafic microgranular enclaves in Maramuni arc, Papua New Guinea

Open Geosciences, 2023
Abstract The Miocene tectonics of Papua New Guinea, where subduction, arc-continent collision, and changes in subduction direction are considered to have occurred, is very complex and various tectonic models have been proposed. The Maramuni arc, active in the Miocene, is composed of a chain of granitoid bodies.
