Tectonic Settings and Petrogenesis of Pan-African S-Type Granitoids in Anka Schist Belt, NW, Nigeria [PDF]

, 2020
Research into geotectonic settings of the Anka schist belt was regionally carried out by (Holt, 1982) stating that there is no evidence of significant partial melting or metasomatism. This research uses chemical data of some Pan-African granitoids within

Indoor - soil gas radon relationshipin the Central Bohemian Plutonic Complex

Annals of Geophysics, 2005
The relationship of indoor radon measurements and radon in bedrock was studied in the granitoid Central Bohemian Plutonic Complex (CBPC). The indoor data were linked to vectorised geological and radon risk maps using the coordinates of ...

Geochemistry and petrology of some granitoids from Papuk and Psunj Slavonian Mountains (Croatia) [PDF]

, 2004
The investigated granitoids of Papuk and Psunj-Krndija Complexes in Slavonia (Croatia) are quartz diorite, granodiorite and monzogranite. Intermediate to highly ordered maximum microcline suggests a slow rate of cooling. The composition of plagioclase is

The petrochemical characteristics of Hercynian granitoids in Tianshan and the geodynamic implications [PDF]

, 2002
Four genetic types of granitoids, i.e. mantle-derived type (M-type), syntexis type (SY-type), trasformation type [T-type, including migmatic(MT), peraluminous (PT) and K-rich (KT) subtypes], and A-type were classified in the Hercynian granitoids in ...

Recycling oceanic crust for continental crustal growth: Sr-Nd-Hf isotope evidence from granitoids in the western Junggar region, NW China [PDF]

, 2012
The juvenile component of accretionary orogenic belts has been declining since the Archean. As a result, there is often controversy regarding the contribution of oceanic basalts to Phanerozoic crustal growth, as in the case of the Central Asian Orogenic ...
