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.
The Commission for the Geological Map of the World (CGMW or CCGM in French) is an international association in the field of geology. Its main role is the production of small-scale maps of continents and oceans, regions of the Earth and the whole World in the field of Geosciences. It is an organization affiliated to IUGS International Union of ...
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
While this was not the world's first geological map (a map of the United States by William Maclure was published six years earlier), [12] [13] Smith's was the first geological map covering such a large area in detail, [14] and is one of the first stratigraphical analyses to utilize palaeontological indices.

One Geology: This interactive geological map of the world is an international initiative of the geological surveys around the globe. This groundbreaking project was launched in 2007 and contributed to the 'International Year of Planet Earth', becoming one of their flagship projects.

The Map that Changed the World is a 2001 book by Simon Winchester about English geologist William Smith and his great achievement, the first geological map of England, Wales and southern Scotland. Smith's was the first national-scale geological map, and by far the most accurate of its time. His pivotal insights were that each local sequence of ...
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
