Petrological diversity of continental arc magmatism evidenced by Triassic magmatic complexes in East Kunlun Orogen [PDF]

open access: yesScientific Reports
Understanding the petrogenetic relationships among the synplutonic dikes, magmatic enclaves and plutons in subduction zones provides key insights into the petrological diversity of arc magmatism.

Magma Mixing Processes in a Continental Collision Zone: Insights From Mineralogical and Geochemical Constraints

open access: yesGeochemistry, Geophysics, Geosystems
Eocene magmatism in southern Tibet records deep geodynamic processes associated with the India‐Asia collision. The Quxu batholith, a representative segment of the Gangdese magmatic belt, hosts widespread mafic microgranular enclaves (MMEs) indicating ...

The Capability of Amphibole in Tracing the Physicochemical Processes of Magma Mixing

open access: yesGeophysical Research Letters
This study explores the capability of amphibole in tracing the physicochemical process of magma mixing through spatially associated gabbros, mafic microgranular enclaves (MMEs) and granodiorites from central Tibet.

Late Mesozoic Tectonic‐Magmatic Evolution of the Tongbai Orogen, Central China: Implications for Granites Petrogenesis and Gold Mineralization

open access: yesGeochemistry, Geophysics, Geosystems
Late Mesozoic granitoids are widely distributed throughout the East Qinling‐Tongbai‐Dabie orogenic belt and its periphery, while large‐scale gold deposits during the same period were primarily found in the Xiaoqinling‐Xiong'ershan area, west of the ...

Petrography, geochemistry and Fractal analysis of Mafic Enclaves in the Alvand Plutonic to investigate magma mixing processes [PDF]

open access: yesپترولوژی, 2021
The Alvand plutonic complex is located in Sanandaj- Sirjan Zone in south and west of Hamedan. Petrographic studies indicate that this body is composed of mafic intrusive rocks, porphyry granitoids and leoucocratic granitoids with various enclaves such as

Investigation of the formation processes in the mafic enclaves of Naqadeh plutonic rocks assemblage by zircon U-Pb dating, Sr-Nd isotopic ratios, and amphibole composition [PDF]

open access: yesپترولوژی, 2021
Naqadeh intrusive pluton is composed of two distinct sections of felsic (40 Ma age) and mafic (99 Ma age) rocks. The granitoid rocks of Naqadeh pluton have different types of mafic enclaves, including mafic microgranular enclaves (MME) and quartz ...

Evidence for magma mixing/mingling process in the plutonic intrusive bodies of Qorveh (Kurdistan Province): with emphasis on textural and geochemical characteristics [PDF]

open access: yesپترولوژی, 2023
The Qorveh batholith, in the N-Sanandaj-Sirjan Zone, comprises several gabbroic, dioritic and granitic masses intruded the Jurassic metamorphic assemblage (i.e., schist, amphibolite and marble). In spite of a number of studies which have been carried out

On the association of Magmatic Microgranular Enclaves (MMEs) and cordierite-bearing monzogranites at the Sierra Bermeja Pluton (SW Spain)

open access: yesGeogaceta, 2021
Magmatic Microgranular Enclaves (MMEs) found within the cordierite-bearing monzogranites of the Sierra Bermeja Pluton (southern Iberian Massif) were investigated to understand their potential petrogenetic relationship.
