Archean rocks with these geochemical features are known as sanukitoids and, despite their limited abundance, are considered to be the indicators of the onset of modern plate tectonics because of their ...

Two additional observations from the Barberton rocks lean toward a more clement climate during the Archean. First, at the proposed temperature of 70°C (Knauth & Lowe 2003), we would expect to see ...

Canadian Journal of Earth Science, 43, 1489-1501. Frost, C.D., Frost, B.R., Kirkwood, R., and Chamberlain, K.R. (2006) The tonalite-trondjhemite-granodiorite (TTG) to granodiortie-granite-monzogranite ...

Eastern Sierra Leone is predominantly ancient Archean crystalline basement rocks, more than 2.5 billion years old, belonging to the Kenema-Man shield. The shield region outcrops elsewhere in the wider ...

Three types of granitoid rocks are central to this geologic origin story—tonalite, trondhjemite, and granodiorite—which together are known as TTG. Evidence of Archean TTG rock can be found ...

We suggest that most Archean SCLM originally consisted of highly depleted dunites/harzburgites, similar to the Archean orogenic massifs of western Norway. Incorporation of such rocks in the cold upper ...

In addition to mountain belt research, we conduct research on seismicity and stress partitioning in continental interiors, basement fault reactivation, investigation of Early Archean geology, and ...
