Diagenesis of Young and Shallowly Buried Sands This research will study the diagenesis of sands that are young and shallow, at depths from 0 to 4000 feet. It will examine Quaternary and Tertiary sands from the Gulf coast, and document changes in texture and mineralogy with shallow burial. The purpose is to document changes in texture and mineralogy that take place in sands during shallow burial and under conditions where pore fluids have ranged from meteoric to hypersaline. Modern samples will be used as a reference for Pleistocene samples, which will be examined in thin section for matrix and pore space. Compaction effects will be studied using an image analyzing system.

浅埋年轻砂岩的成岩作用 这项研究将研究砂岩的成岩作用， 年轻而浅，从0到4000英尺的深度。 它将审查 墨西哥湾沿岸的第四纪和第三纪砂， 结构和矿物学的变化与浅埋。 的 目的是记录纹理和矿物学的变化， 在浅埋和以下条件下， 孔隙流体的范围从大气到高盐。 现代 样品将被用作更新世样品的参考， 将在薄切片中检查基质和孔隙。 压实效果将使用图像分析进行研究 系统
