Bedrock Geology

Bedrock Geology Set is a 1:50,000-scale, polygon and line feature-based layer describing the solid material that underlies the soil or other unconsolidated material of the earth for Connecticut. Bedrock geologic formations are described as polygons in terms of formation name (incorporating geologic age), rock type, and tectonic terrane association. Tectonic forces are responsible for the present day geologic configuration of the continents. Resulting terranes are regionally fault bounded rocks of a similar tectonic history. Each terrane is named after its plate tectonics ancestry. Geologic lines include contacts, faults, and terrane boundaries. Terrane boundaries are named for the faults involved. The geologic contacts and faults are delineated and classified by type. Polygon feature attribute information is comprised of codes to identify individual bedrock geologic units, their formation name, description and size. Line feature attributes identify, name and describe bedrock contacts, faults and terrane boundaries between these bedrock geologic units. Data is compiled at 1:50,000 scale and is not updated. A complete description of the bedrock mapping units with mineralogical descriptions and a brief history of Connecticut geology are included in the Supplemental Information Section for reference.

基岩地质数据集（Bedrock Geology Set）是一套1:5万比例尺、基于面状与线状要素的图层，用于描述康涅狄格州境内覆于土壤或其他松散沉积物之下的固态基岩。基岩地质地层以面状要素形式表达，其属性涵盖地层名称（整合地质年代信息）、岩石类型与构造地体组合特征。构造作用力塑造了现今大陆的地质格局，由此形成的地体为受区域性断层围限、具有相似构造演化历史的岩体，各地体以其板块构造起源命名。地质线状要素包括接触界线、断层与地体边界，其中地体边界以其所依附的断层命名。地质接触界线与断层均按类型进行勾绘与分类。面状要素的属性信息通过编码实现单个基岩地质单元的识别，并包含其地层名称、描述信息与规模参数。线状要素属性则用于识别、命名并描述上述基岩地质单元之间的基岩接触界线、断层及地体边界。本数据集以1:5万比例尺编制完成，未进行后续更新。补充信息章节收录了带矿物学描述的基岩填图单元完整说明，以及康涅狄格州地质简史，可供参考。
