Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract The Yangtze Craton in South China is generally regarded as an Archean‐Paleoproterozoic continental nucleus with a coherent basement that collided with the Cathaysia Block in the Early Neoproterozoic. Here we reprocessed a 300‐km‐long NW‐trending seismic reflection profile in the eastern Yangtze Craton.

Late-orogenic Svecofennian deformation in SW Finland constrained by pegmatite emplacement ages
, 1996 Late stages of the Svecofennian orogeny in SW Finland were related to a tranpressional stress field and dextral movements along crustal scale shear zones under decreasing temperature and pressure conditions.

New aspects to the geology of the Outokumpu region [PDF]
Bulletin of the Geological Society of Finland, 1976 This study provides a general picture of the geology of the Outokumpu region with no attempt at being a detailed description. Special attention is paid to the areas occupied by Karelian and Prekarelian rocks and the location of the Outokumpu region in ...

Broadband seismic data acquisition and processing of iron oxide deposits in Blötberget, Sweden
Geophysical Prospecting, Volume 73, Issue 1, Page 80-95, January 2025.Abstract In June 2022, an innovative seismic survey was conducted in Blötberget, central Sweden, to evaluate the effectiveness of employing both a broadband seismic source and broadband receivers for mineral exploration in a challenging hardrock setting. The Blötberget mine hosts high‐quality iron oxides, predominantly magnetite and hematite, sometimes

New monazite U-Pb age constraints on the evolution of the Paleoproterozoic Vaasa granitoid batholith, western Finland [PDF]
Bulletin of the Geological Society of Finland, 2016 The Vaasa batholith, western Finland, is a large, peraluminous granitoid pluton that crystallized at 1.88–1.87 Ga during the culmination of the Svecofennian orogeny.

Basin Research, Volume 36, Issue 6, November–December 2024.First detrital zircon provenance study of the Billefjorden Group on Bjørnøya, Svalbard. The East Greenland Caledonides formed a long‐lived source terrain in northeast Greenland. Syn‐sedimentary faulting, drainage shifts and changing fluvial styles have little influence on detrital zircon age spectrum.

Geochemical and boron isotopic compositions of tourmalines from selected gold-mineralised and barren rocks in SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2010 Tourmaline-bearing rocks and a number of gold occurrences coexist in southwestern Finland, in a region where extensive magmatism and hydrothermal systems occurred during the Svecofennian orogeny, 1.9-1.8 Ga ago.
