Lithofacies, chronostratigraphy, minerals and diagenetic silica facies at DSDP Leg 80 Holes@en

X-ray powder diffraction and optical and scanning-electron microscope analyses of sediment samples taken from four sites drilled in the Goban Spur area of the northeast Atlantic show variable diagenetic silicification of sediments at several stratigraphic horizons. The results are as follows: […]对东北大西洋戈班斯普尔（Goban Spur）区域四个钻探站位采集的沉积物样品开展X射线粉末衍射（X-ray powder diffraction）、光学显微镜（optical microscope）及扫描电子显微镜（scanning-electron microscope）分析，结果显示多个地层层位处的沉积物存在程度各异的成岩硅化作用。具体结果如下：[…]
