  2. Geological survey - Wikipedia

    en.wikipedia.org/wiki/Geological_survey

    A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...

    At lower latitudes, near 30° north, a 7.5-minute quadrangle contains an area of about 64 square miles (166 km 2). At 49° north latitude, 49 square miles (127 km 2) are contained within a quadrangle of that size. As a unique non-metric map scale, the 1:24,000 scale naturally requires a separate and specialized romer scale for plotting map ...

  8. Geologic map - Wikipedia

    en.wikipedia.org/wiki/Geologic_map

    A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
