A geologic section has to fulfill a set of criteria to be adapted as a GSSP by the ICS. The following list summarizes the criteria: [2] [3] A GSSP has to define the lower boundary of a geologic stage. The lower boundary has to be defined using a primary marker (usually first appearance datum of a fossil species).
This is a list of Global Boundary Stratotype Sections and Points. Since 1977, Global Boundary Stratotype Sections and Points (abbreviated GSSPs) are internationally agreed upon reference points on stratigraphic sections of rock which define the lower boundaries of stages on the geologic time scale .
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.
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.
The Giant's Causeway (Irish: Clochán an Aifir) [1] is an area of approximately 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. [3] [4] It is located in County Antrim on the north coast of Northern Ireland, about three miles (4.8 km) northeast of the town of Bushmills.
A game reserve (also known as a game park) is a large area of land where wild animals are hunted in a controlled way for sport. [1] If hunting is prohibited, a game reserve may be considered a nature reserve; however, the focus of a game reserve is specifically the animals , whereas a nature reserve is also, if not equally, concerned with all ...
The geology of Ireland is diverse. Different regions contain rocks belonging to different geological periods, dating back almost 2 billion years. The oldest known Irish rock is about 1.7 billion years old and is found on Inishtrahull Island off the north coast of Inishowen [4] [5] and on the mainland at Annagh Head on the Mullet Peninsula. [6]
The Kololo Game Reserve covers 3000 hectares, part of which is in the Welgevonden Private Game Reserve, and part of which is completely protected. [9] The Lapalala Wilderness Nature Reserve, just north of Melkrivier covers approximately 48’000 hectares and is the largest private game reserve in the Waterberg and the Limpopo province.
