The Proterozoic granitoids of Finland: Granite types, metallogeny and relation to crustal evolution [PDF]
Bulletin of the Geological Society of Finland, 1986 The granitoids are divided into four main groups: synkinematic (1860‒1930 Ma, most commonly 1870‒1890 Ma), late-kinematic (1800‒1850 Ma) and postkinematic (ca. 1800 Ma) Svecokarelian granitoids, and anorogenic rapakivi granites (1540‒1700 Ma).

Geophysical Prospecting, Volume 71, Issue 7, Page 1181-1196, September 2023., 2023 Abstract Two legacy reflection seismic profiles were acquired in 1988, north of the Kloof–Driefontein Complex East Mine in the West Rand goldfield (South Africa), for the purpose of gold exploration and mine planning. These legacy 2D seismic data have been reprocessed using the latest processing tools to improve imaging.

Journal of Metamorphic Geology, Volume 41, Issue 7, Page 997-1030, September 2023., 2023 Abstract The Dom Feliciano Belt of southern Brazil and Uruguay represents part of a larger Neoproterozoic orogenic system formed during the amalgamation of Western Gondwana. The hinterland and foreland domains in parts of the belt preserve deformation structures and metamorphic assemblages that developed during early crustal thickening from c.

Earth Surface Processes and Landforms, Volume 48, Issue 10, Page 2039-2056, August 2023., 2023 We address the relationship between the bedrock structure and bedrock surface topography through conducting structural analysis of the bedrock within the main recharge area of the Kurikka aquifer. Based on the presented results, it is evident that the initial bedrock‐digital elevation model (DEM) with smooth elevation transitions from the elevated ...

Meteoritics &Planetary Science, Volume 58, Issue 7, Page 1002-1017, July 2023., 2023 Abstract The Summanen structure is located in Central Finland and is one of Finland's 12 known meteorite impact structures. In 2017, the discovery of Summanen was based on numerous shatter cone boulders with planar deformation features (PDFs) and a circular electromagnetic anomaly, which is 2.6 km in diameter.
