Journal of Metamorphic Geology, Volume 44, Issue 4, Page 265-286, May 2026.ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

The geologic potentials of Riau Islands Province and its development design
Jurnal Perspektif Pembiayaan dan Pembangunan Daerah, 2018 Geologically Riau Islands is located in the topography of the old stadium erosion. The morphology is characterized by smooth hills with convex slopes and alluvial plain consisting of the erosion products. The morphology exhibits the remnants of peneplain

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract When, where, and how much fluid is released from subducting oceanic crust control deformation, element cycling, and magmatism in subduction zones. However, the palimpsest of tectonometamorphic processes in the exhumed rock record complicates the relation of geologic observations to geodynamic models of subduction fluid sources and transport ...

Dehydroxylation of Minerals of Gadisunkapur Area with Special Reference to FTIR and Thermal Study
International Journal of Economic and Environment Geology, 2020 This paper attempts to explain the presence of OH group for micas along with some sulfate, chlorite, quartz and feldspar minerals. These minerals are found to be associated with barite vein, metasediments (quartz-chlorite schist ...

Comparison of metamorphic evolution and tectonic position of metasediments of the Austevoll islands with rocks from the Samnanger Complex (Major Bergen Arc, Norwegian Caledonides) [PDF]
, 2015 Metasedimentary rocks represent a substantial component of the Bergen Arcs System and they are mostly confined to the Minor and Major Bergen Arcs. The arcs represents imbricate structures composed of island arc lithologies, prism sediments and gneissic ...
