Industry:Mining
A map showing the distribution of different types of rock attributes or facies occurring within a designated geologic unit.
Industry:Mining
A map showing the topographic features of a land surface, commonly by means of contour lines. It is generally on a sufficiently large scale to show in detail selected manmade and natural features, including relief, and such physical and cultural features as vegetation, roads, and drainage. Compare: planimetric map
Industry:Mining
A map showing, by contours, the areas having an equal quantity of carbon within an assumed interval of stratigraphic section.
Industry:Mining
A map that depicts isoliths; esp. a facies map showing the net thickness of a single rock type or selected rock component in a given stratigraphic unit.
Industry:Mining
A map that portrays the architecture of the outer part of the Earth. It is similar to a structure-contour map, which primarily shows dipping strata, folds, faults, and the like, but the tectonic map also presents some indication of the ages and kinds of rocks from which the structures were made, as well as their historical development.
Industry:Mining
A map that presents only the relative horizontal positions of natural or cultural features, by lines and symbols. It is distinguished from a topographic map by the omission of relief in measurable form.
