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.
[11] [12] Thus, the criteria, i.e. (1.) its sediments being all of the same age, (2.) it consisting of sediments deposited during a single interglacial period, and (3,) as originally defined by Leverett in 1898 consist of interglacial sediments, by which the Yarmouthian (Yarmouth) Interglacial (Stage) was defined and recognized have all been ...
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.
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. A UCD Digital Library Collection.
Digital geologic mapping is the process by which geological features are observed, analyzed, and recorded in the field and displayed in real-time on a computer or personal digital assistant (PDA). The primary function of this emerging technology is to produce spatially referenced geologic maps that can be utilized and updated while conducting ...
The Oxfordian is, in the ICS' geologic timescale, the earliest age of the Late Jurassic Epoch, or the lowest stage of the Upper Jurassic Series. It spans the time between 161.5 ± 1.0 Ma and 154.8 ± 0.8 Ma (million years ago). [3] The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian.
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. [3]
