STATEMAP Geology

This layer represents the surficial and near-surface geology for over 20 years of STATEMAP geologic mapping. Each polygon represents the lithostratigraphic unit that is at or near the surface. Polygons were mapped at the 1:24,000 scale using samples from the FGS cores and cuttings repository, new core samples taken during the course of the project, extensive field work and surface sample collection, and computer modelling. Please note that much of Florida is covered with undifferentiated sediments, and by convention the FGS maps the first recognizable lithostratigraphic unit occurring within 20 feet of the land surface. Areas with >20 ft of undifferentiated sediments are mapped as Qu or Qbd. The original, published maps and reports for the STATEMAP projects can be found in the Open File Map Series and Open File Reports published by the Florida Geological Survey (Tallahassee, FL). For the original published maps and reports, please see the Library page at https://floridadep.gov/fgs/data-maps/content/fgs-publications or the STATEMAP StoryMap at https://experience.arcgis.com/experience/764386bec4fe4bd19c397e1b2f576e85本图层基于长达20余年的STATEMAP地质填图项目成果，展示研究区的地表及近地表地质特征。每个多边形对应地表或近地表产出的岩石地层单位（lithostratigraphic unit）。该图层以1:24000比例尺完成填绘，数据来源包括佛罗里达地质调查局（Florida Geological Survey，简称FGS）的岩心与岩屑库样品、项目期间采集的全新岩心样品、大规模野外调查与地表样品采集工作，以及计算机模拟分析。请注意，佛罗里达州大部分区域被未分化沉积物覆盖，按照行业惯例，FGS仅标注距地表20英尺范围内首个可识别的岩石地层单位。沉积物厚度超过20英尺的未分化沉积物区域，以地层代号Qu或Qbd进行填绘。STATEMAP项目的原始正式出版图件与报告，可在佛罗里达地质调查局（位于佛罗里达州塔拉哈西市）发布的公开图件系列(Open File Map Series)与公开报告系列(Open File Reports)中获取。如需获取原始出版资料，请访问其公开出版物库页面：https://floridadep.gov/fgs/data-maps/content/fgs-publications，或STATEMAP专题故事地图（StoryMap）：https://experience.arcgis.com/experience/764386bec4fe4bd19c397e1b2f576e85
