Mapped global geologic provinces. 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.
Oblique aerial photograph covering the Cappadocia, nearby Gorëme, Turkey.. Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. [1]
The full official Indonesian name is the Pusat Vulkanologi dan Mitigasi Bencana Geologi (English: Volcanology and Geological Hazard Mitigation Center), often abbreviated to PVMBG. [1] It is based in Bandung in West Java. [2] It was preceded by the Netherlands East Indies Volcanological Survey. [3]
Incorporating the spatial positions of the major formation boundaries, including the effects of faulting, folding, and erosion (unconformities).The major stratigraphic divisions are further subdivided into layers of cells with differing geometries with relation to the bounding surfaces (parallel to top, parallel to base, proportional).
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

Theatrum Orbis Terrarum (Latin: [tʰɛˈaːtrũː ˈɔrbɪs tɛˈrːaːrũː], "Theatre of the Lands of the World") is considered to be the first true modern atlas.Written by Abraham Ortelius, strongly encouraged by Gillis Hooftman [2] and originally printed on 20 May 1570 in Antwerp, [3] it consisted of a collection of uniform map sheets and supporting text bound to form a book for which ...
Specifically in sedimentology, a bed can be defined in one of two major ways. [2] First, Campbell [3] and Reineck and Singh [4] use the term bed to refer to a thickness-independent layer comprising a coherent layer of sedimentary rock, sediment, or pyroclastic material bounded above and below by surfaces known as bedding planes.
Aerial view of the almost flat and drowned peneplain at Belcher Islands, Hudson Bay, Canada, cutting across numerous geologic folds.. In geomorphology and geology, a peneplain is a low-relief plain formed by protracted erosion.
