Boron, sulphur and copper isotope systematics in the orogenic gold deposits of the Archaean Hattu schist belt, eastern Finland

, 2016
The Hattu schist belt is located in the western part of the Archaean Karelian domain of the Fennoscandian Shield. The orogenic gold deposits with Au–Bi–Te geochemical signatures are hosted by NE–SW, N–S and NW–SE oriented shear zones that deform 2.76–2 ...

Coupling deformation and fluid P-V-T-X conditions in orogenic gold deposits

, 2009
Deformation is intimately linked to fluid conditions in fault related ore systems such as orogenic gold deposits. Orogenic gold fluids are characterised by complex CO2-H2O-NaCl fluids with XCO2 values typically between 0.1 and 0.3 and salinities of 3 to ...
