Deep Groundwater Evolution at Outokumpu, Eastern Finland : From Meteoric Water to Saline Gas-Rich Fluid [PDF]

, 2017
Within Precambrian continental shields, saline, gas-rich groundwaters are found in all over the world from bedrock fractures and pore spaces in the upper crust.

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.

Precambrian geodynamics and ore formation : the Fennoscandian Shield

, 2006
The complex geodynamic evolution of the Fennoscandian Shield from 2.06 to 1.78 Ga involved rapid accretion of island arcs and several microcontinent-continent collisions in a complex array of orogens. With a few exceptions, all major ore deposits formed in specific tectonic settings between 2.06 and 1.78 Ga and thus a strong geodynamic control on ore ...
