Carbonate, organic carbon, pyrolysis and composition of the extracts at DSDP Holes 76-534A and 44-391

The geochemical studies of Sites 534 and 391 and their comparison allow us to improve the chemical characterization of different geological formations dating from the early Callovian to the Maestrichtian along the continental margin of eastern North America. […]对534号与391号钻探站位的地球化学研究及其对比分析，可优化北美东部大陆边缘沿线、形成于早卡洛维阶（early Callovian）至马斯特里赫特阶（Maestrichtian）的各类地质地层的化学特征表征。[…]
