Strontium- and lead-isotope composition of some basalts at DSDP Hole 69-504B

Seventeen whole-rock samples, generally taken at 25- to 50-meter intervals from 5 to 560 meters sub-basement in Deep Sea Drilling Project Hole 504B, were analyzed for 87Sr/86Sr...本研究对取自深海钻探计划（Deep Sea Drilling Project）504B钻孔基底以下5至560米深度、采样间距通常为25至50米的17件全岩样品的87Sr/86Sr比值进行了分析。
