3D model of a clastic, shallow marine outcrop in the Western Interior Basin (Parkman Sandstone, Judith River Formation, Cretaceous)

Two 3-dimensional models from the Parkman sandstone, at the base of the Judith River Formation (Cretaceous). The study area is located west of the town of Bridger (Montana, USA). These models were acquired for the analysis of lateral and vertical stratigraphic heterogeneities in clastic, shallow marine environments. The models cover a cliff section of, approximately, 1500 m in the horizontal direction and 150 m in the vertical direction.<br>The resolution of the models, measured in GSD (ground sample distance), varies between 0.03 and 0.04 m.

本数据集包含两件采自白垩纪朱迪河组（Judith River Formation）底部帕克曼砂岩（Parkman sandstone）的三维地质模型。研究区位于美国蒙大拿州布里杰（Bridger）镇西侧，这些模型的构建旨在分析碎屑岩浅海环境中的侧向与垂向地层非均质性。模型覆盖的悬崖剖面水平跨度约1500米，垂向高度约150米。
模型的分辨率以地面采样距离（GSD, ground sample distance）为衡量标准，取值范围为0.03米至0.04米。
