This service uses two geologic base maps; the 1:500,000-scale geologic map of Kentucky at scales smaller than 1:100,000, and 1:24,000-scale geological quadrangle data at larger scales. The 1:500,000-scale geologic map data were derived from the 1988 Geologic Map of Kentucky, which was compiled by Martin C. Noger (KGS) from the 1981 Geologic Map of Kentucky (Scale 1:250,000) by McDowell and others (USGS). The 1:24,000-scale geologic map data and the fault data were compiled from 707 Geological Survey 7.5-minute geologic quadrangle maps, which were digitized during the Kentucky Geological Survey Digital Mapping Program (1996-2006).

This map service depicts the boundaries of the Earth's major tectonic plates and fault lines. Tectonic plates are large plates of rock that make up the foundation of the Earth's crust and the shape of the continents. The plates comprise the bottom of the crust and the top of the Earth's mantle. The plates are most famously known for being the source of earthquakes. A fault is a fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of earth movement. Large faults within the Earth's crust result from the movement of tectonic plates.

This dataset shows 1:250,000 scale faults/lineaments of the Precambrian Shield area of Saskatchewan. This dataset shows the 1:250,000 scale bedrock geology faults/lineaments of the Precambrian Shield area of Saskatchewan. The faults/lineaments layer has been merged from the 1:250,000 scale Compilation Bedrock Geology map series.  **Please Note – All published Saskatchewan Geological Survey datasets, including those available through the Saskatchewan Mining and Petroleum GeoAtlas, are sourced from the Enterprise GIS Data Warehouse. They are therefore identical and share the same refresh schedule.

This dataset is the digital compilation of the 1:1 million scale faults and fault systems for the Province of Saskatchewan. This dataset represents the 1:1 million scale major faults or fault system of the Province of Saskatchewan, Canada. Mapping in support of this dataset includes many years of field observations which were then compiled at 1:1 million scale and integrated into this dataset. The data was created as a file geodatabase feature class and output for public distribution.  To view or download more datasets from the Saskatchewan Geological Survey, please visit our GeoHub page (https://er-saskatchewan.hub.arcgis.com/pages/saskatchewan-geological-survey) or our Saskatchewan Mining and Petroleum GeoAtlas (https://gisappl.saskatchewan.ca/geoatlas). **Please Note – All published Saskatchewan Geological Survey datasets, including those available through the Saskatchewan Mining and Petroleum GeoAtlas, are sourced from the Enterprise GIS Data Warehouse.
