Plate 5 _ Sand_distribution model

This map includes three-dimensional models that show the distribution of the Quaternary sand and gravel deposits that are potential aquifers in Yellow Medicine County, Minnesota. Geologists interpreted the three-dimensional models and related sand and gravel deposits to the glacial events that formed them. Although the models and interpretations are based on the best available data, they are unavoidably incomplete due to a lack of data in some areas.本数据集包含三维模型，用于展示明尼苏达州黄麦迪逊县（Yellow Medicine County）境内作为潜在含水层（aquifers）的第四纪（Quaternary）砂卵石沉积的分布情况。地质学家对上述三维模型及相关砂卵石沉积开展解译工作，并将其与形成它们的冰川事件相关联。尽管本模型与解译成果基于当前可获取的最优数据，但由于部分区域数据缺失，不可避免地存在不完备之处。
