Abstract

Abstract

It is significant to study the relationship between Co-rich crust composition and its growing environmentfor accurate estimate and rational utilization of this future resource. The authors present carbon isotope data of organic matter in Co-rich ferromanganese crust from central Pacific seamount area. The value of δ¹³C_org ranges from -21.86×10^-3 to -23.99×10^-3, implying that the organic matter origins from marine organism. The carbon isotopic composition of organic matter fluctuates during the growth of Co-rich crust and responds to marine environment and global climate change. Hence, it can be a useful proxy for paleoceanography.
