Layer-by-layer correlation of ODP Leg 117 sites@en

One hundred thirty-one marker horizons relating to the distinct and traceable layers were described for the Owen Ridge and Oman Margin sites. The correlations incorporated the calculations of true depth, corrected for coring disturbance and gas expansion. Intersite correlation of marker horizons has been improved based on color density data, measured with video densitometer, and oxygen isotope stratigraphic data. […]针对欧文海岭（Owen Ridge）与阿曼陆缘（Oman Margin）的钻探站位，共记录了131处可清晰识别、可追溯的标志层（marker horizon）。本次地层对比工作纳入了经取芯扰动与气体膨胀校正后的真实深度计算结果。基于视频光密度计（video densitometer）实测的颜色密度数据与氧同位素地层数据，标志层的站位间对比精度得到了显著提升。[…]
