B, d11B, K and δ¹⁸O data for altered oceanic crust at DSDP Sites 417/418

Samples of drilled oceanic crust, from DSDP Holes 417A, 417D and 418A and ODP Hole 735B, and oceanic crust from the Oman and Cyprus ophiolites, were analyzed for B contents and d11B. Composite samples from DSDP Holes 417A, 417D and 418A were used to represent the upper 550 m of altered oceanic crustal Layer 2A. Whole-rock samples from the Troodos ophiolite, Cyprus, and the Oman ophiolite were selected to represent crustal Layer 2B dikes. Composite samples from ODP Hole 735B were used to represent crustal Layer 3. […]

本研究对取自深海钻探计划（Deep Sea Drilling Project, DSDP）417A、417D、418A钻孔及大洋钻探计划（Ocean Drilling Program, ODP）735B钻孔的钻探洋壳样品，以及阿曼、塞浦路斯蛇绿岩套中的洋壳样品，开展了硼（B）含量与δ¹¹B（原文标注为d11B）同位素比值分析。其中，取自DSDP 417A、417D与418A钻孔的组合样品，用于表征蚀变洋壳第二层A段上部550米的地层；取自塞浦路斯特罗多斯蛇绿岩套与阿曼蛇绿岩套的全岩样品，被选为地壳第二层B段岩墙群的代表；而取自ODP 735B钻孔的组合样品，则用于表征地壳第三层。[…]
