The Taivaljärvi Silver Mine Ag-Au-Zn deposit in eastern Finland is located in the Archean Tipasjärvi greenstone belt (), in the southern part of a north-trending, about km long and from 3–5 km wide, Tipasjärvi-Kuhmo-Suomussalmi greenstone complex that is a part of the Archean Kianta terrane (Sorjonen-Ward and Luukkonen, ).Several studies discuss the geology and geochemistry of the Cited by: 1.

During the remobilization process, Au and Ag were decoupled, which resulted Archean Au-Ag- book (1) a change in Au/Ag ratios of to 5 in early pyrite to ≈9 in the new native gold ( Au fineness) and (2) incorporation of Ag into cogenetic secondary mineral phases (e.g., chalcopyrite, tetrahedrite, and galena).Author: Evan C.G.

Hastie, Daniel J. Kontak, Bruno Lafrance. Archean greenstones are structurally and stratigraphically complex. Although thicknesses up to 20 km have been reported, because of previously unrecognized tectonic duplication, it is unlikely that any sections exceed 5 km (Condie, ).Most Archean greenstones are composed chiefly of subaqueous basalts (Figure ) and komatiites (ultramafic volcanics) with minor amounts of felsic tuff and.

The ratio of ferric vs. ferrous iron varies greatly. An ideal end-member "ferrostilpnomelane" can be represented by K 5 Fe 48 2+ (Si 63 Al 9)O (OH) H 2 O.

The 8th International Conference on Basement Tectonics was held in Butte, Montana, AugustHistorically, basement tectonics conferences have focused on such topics as reactivation of faults, the influence of basement faults on metallogeny and hyrocarbon accumulation, and the use of geophysical and remote sensing techniques to interpret subsurface and surface geology.

He has authored or co-authored approximately papers and book chapters, largely on Archean evolution, komatiite-associated Ni-Cu deposits, orogenic gold deposits, the role of lithosphere in global metallogeny, and prospectivity mapping.1.

Introduction [2] Compared with modern tectonic systems, the geological record of Precambrian tectonic systems is often sparsely preserved, temporal constraints are often fuzzy or lacking, and there is greater potential for reworking during younger tectonic activity.

Consequently, tectonic interpretations for Precambrian events are often ambiguous and subject to high degrees of by:
