Three-Dimensional Geometry of Late Pleistocene Mixing Zone Dolomite, Southeastern Barbados, West Indies

晚更新世混合带的三维几何形状 白云岩，巴巴多斯东南部，西印度群岛。 早期近地表白云岩往往无明显关系 成岩环境为钾长石或高盐成岩环境。 稀释 大气水和海水的混合物既能吸收钙， 碳酸盐溶解和白云石沉淀。 混合带白云岩的最佳研究实例是在 加勒比海，但对它们的几何形状知之甚少。 在巴巴多斯 其几何形状似乎是由古水文控制的 背景，与前更新世古地形有关。 研究 将进行一个岩心钻探项目。 钻取的岩心将 用于研究岩性、稳定同位素和微量元素 在混合区。

Three Dimensional Geometry of Late Pleistocene Mixing Zone Dolomite, Southeastern Barbados, West Indies. Early near-surface dolomite often has no obvious relationship to evaporitic or hypersaline diagenetic environments. Dilute mixtures of meteoric and marine water are capable of both calcium carbonate dissolution and the precipitation of dolomite. The best studied examples of mixed zone dolomite is in the Caribbean, but little is known of their geometries. In Barbados the geometry seems to be controlled by the paleo-hydrologic setting, relating to pre-Pleistocene paleotopography. The study will conduct a core-drilling project. The drilled cores will be used to study the lithology, stable isotopes, and trace elements of the mixed zone.
