Sloc Chiasgeo

Sloc Chiasgeo is shown as a bay on the public map of Na h-Eileanan Siar. The saved point is the map point or the centre of its mapped shape.

Sloc Chiasgeo is a coastal rock feature located within the Na h-Eileanan Siar archipelago, composed primarily of Lewisian gneiss, some of the oldest rocks in the British Isles, dating back over 2.7 billion years. These metamorphic rocks formed through high-pressure and high-temperature deformation of ancient igneous and sedimentary rocks, and are notable for their durability and the insight they provide into early Earth crustal processes.
