Bedrock geological map of Ireland. Layers of Upper Carboniferous sedimentary rocks, Loop Head, County Clare. The geology of Ireland consists of the study of the rock formations on the island of Ireland. It includes rocks from every age from Proterozoic to Holocene and a large variety of different rock types is represented.
Geological Survey Ireland produces maps, reports and databases, and acts as a knowledge centre and project partner in a number of aspects of Irish geology. [ 3 ] The organisation managed the Irish National Seabed Survey (INSS, 1999–2005), which on completion was the world's largest civilian marine mapping programme.
Historic Maps Collection. 18th and 19th-century historic maps of Ireland. A UCD Digital Library Collection. Maps of Dublin accompanying Thom's Official Directory, printed by the Ordnance Survey for the Dublin publisher Alexander Thom from the six-inch map sheets 18 and 22, and dating from the late 19th century.
The secant lines of isograds with the surface form lines on a geologic map. Changes in mineralogical composition in a terrane reflect differences in metamorphic grade of the rocks. Minerals that are characteristic for a certain metamorphic grade are called index minerals. The first or last appearance of an index mineral (the place where a ...
Geologic map of North America. The geology of North America is a subject of regional geology and covers the North American continent, the third-largest in the world. Geologic units and processes are investigated on a large scale to reach a synthesized picture of the geological development of the continent. The divisions of regional geology are ...
OneGeology is an international collaborative project in the field of geology supported by 118 countries, UNESCO, and major global geoscience bodies.It is an International Year of Planet Earth flagship initiative that aims to enable online access to dynamic digital geological map of the world for everyone.
On Earth, they constitute some of the most common landscapes. [2] Geological maps indicate that planation surfaces may comprise 65% of the landscapes on Saturn's largest moon, Titan, [3] which hosts a hydrological cycle of liquid methane. Peneplains and pediplains are types of planation surfaces planated respectively by "peneplanation" and ...
Geological maps of County Donegal show rock alignments running south-west to north east across the Fanad peninsula. The underlying rock in the peninsula is mostly of Dalradian meta-sedimentary rocks, which have been exposed by weathering and erosion over the millennia There are areas of Granodiorite igneous rocks across the northern end of the peninsula from Ballywhoriskey to Fanad Head, but ...
