Orkney Basin

The Orkney Basin is a geological feature that developed in the Devonian Period, approximately 419 to 359 million years ago. This basin formed on top of the thickened and unstable crust of the Caledonian orogenic belt, a process comparable to modern rifts in Tibet. The erosion of the uplifted mountains during this period led to the deposition of sandstones and conglomerates across a wide region, including the British Isles and the western Russian Platform, collectively known as the Old Red Sandstone continent.1

The Orkney Islands themselves, located north of mainland Scotland, were shaped by glacial erosion of underlying sandstone, limestone, and igneous rocks. These islands have a rich history of human occupation, with significant prehistoric sites like Skara Brae, a well-preserved Neolithic village. The islands were later colonized by Norse settlers in the 9th century and eventually passed to Scottish rule in 1472. Today, Orkney is a prosperous farming area and has seen economic activity related to North Sea oil exploitation.23
