Abstract: Tonalite–trondhjemite–granodiorite gneisses (TTG) and K-rich granites are extensively exposed in the Mesoarchean to Paleoproterozoic Bundelkhand craton of central India. The TTGs rocks are coarse- grained with biotite, plagioclase feldspar, K-feldspar and amphibole as major constituent… read more here.

DOI: 10.1130/g49287.1

Abstract: Tonalite-trondhjemite-granodiorite (TTG) suites are the dominant component of Earth’s first continents, but their origins are debated. The trace element concentrations of these rocks are conventionally linked to their source depths and inferred geodynamic settings with… read more here.
