Research Abstract |
We did following four topics to understand Mesoarchean to Paleoproterozoic ocean floor environment. 1) 3.2Ga DXCL drilling project: 200m long fresh black shale-iron formation had been drilling and we collected flesh sample. 2) Lateral variation of Cleaverville iron formation in coastal Pilbara terrane, Western Australia. 3) Geochemical analysis (isotope C, S) shows ocean environment at 3.2 Ga already prepare to oxidation produce system at near the island arc condition. 4) 2.2Ga Berimian greenstone belt in Ghana have been preserved excellent oceanic sequence at that time. We reconstructed deep ocean island arc stratigraphy at this area.
