Old Red SandstoneThe Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the eastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica/Laurussia. In Britain it is a lithostratigraphic unit (a sequence of rock strata) to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology.
Scottish LowlandsThe Lowlands (Lallans or Lawlands; , ˈaˈɣauɫ̪t̪əxk) is a cultural and historical region of Scotland. Culturally, the Lowlands and the Highlands diverged from the Late Middle Ages into the modern period, when Lowland Scots replaced Scottish Gaelic throughout most of the Lowlands. The Lowlands is not an official geographical or administrative area of the country. There are two main topographic regions: the Lowlands and the Southern Uplands. The term "Lowlands" mainly refers to the Central Lowlands.
AberdeenshireAberdeenshire (Aiberdeenshire; Siorrachd Obar Dheathain) is one of the 32 council areas of Scotland. It takes its name from the County of Aberdeen, which has substantially different boundaries. The Aberdeenshire Council area includes all of the area of the historic counties of Aberdeenshire and Kincardineshire (except the area making up Aberdeen City council area), as well as part of Banffshire. The county boundaries are officially used for a few purposes, namely land registration and lieutenancy.
Scottish HighlandsThe Highlands (the Hielands; a’ Ghàidhealtachd ə ˈɣɛːəl̪ɣt̪həxk, 'the place of the Gaels') is a historical region of Scotland. Culturally, the Highlands and the Lowlands diverged from the Late Middle Ages into the modern period, when Lowland Scots replaced Scottish Gaelic throughout most of the Lowlands. The term is also used for the area north and west of the Highland Boundary Fault, although the exact boundaries are not clearly defined, particularly to the east.
