| Research Abstract |
Reconstracted ocean floor environment at Acehan and Proterozoic Project focus to deep sea sedimentary rocks which destributed well preserved stratigraphic condition portion. We did geological mapping, drilling and geochemical analysis.Especially, DXCL drilling project successfully done in 2007.We get 200m long 3.2Ga sedimentary sequence and get Organic carbon rich black shale's sequence. These result shows very wide and intense biological activity already occur in this time.
