Geochemistry of minerals at DSDP Holes 68-501 and 69-504B

The interaction of seawater with basalts in DSDP Hole 501 and the upper part of Hole 504B (Costa Rica Rift) produced oxidative alteration and a zonation of clay minerals along...深海钻探计划（Deep Sea Drilling Project，DSDP）501号钻孔与哥斯达黎加裂谷504B号钻孔上部的海水与玄武岩相互作用，引发了氧化蚀变，并沿……形成了黏土矿物分带。
