EARLY PRECAMBRIAN CRUSTAL EVOLUTION OF THE BELOMORIAN AND TRANS-NORTH CHINA OROGENS AND SUPERCONTINENTS RECONSTRUCTION

Геодинамика и тектонофизика, 2017
Comparative analysis of the crustal evolution of the Early Precambrian Belomorian and Trans-North China orogens (Fig. 1) has shown [Slabunov et al., 2015] that: Both belts were formed by the superposition of two Precambrian orogenies.

The urosozero greenstone structure (Fennoscandian shield): geology, composition, age and metamorphism of the volcanics

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016
The results of detailed study of the Urosozero greenstone structure (northwestern part of the Vodlozero domain) of the Fennoscandian Shield are presented. The composition and the U-Pb zircon age of the volcanic rocks were studied. The Urosozero structure

Strike-slip faulting and hydrothermal alteration in a Proterozoic rapakivi batholith: implications for reservoir formation and geothermal exploration in crystalline cratons—Part 1

Geothermal Energy
Ancient crystalline basement cratons are traditionally considered challenging geothermal targets due to their low heat flow, limited porosity, and low matrix permeability.
