Depression by the roadside, overlooking Keem Strand. Has been systematically excavated, including by mechanical digger, to provide specimens for sale to tourists. Much of what is offerred locally nowadays is actually South American!
Very little can be found nowadays and collecting is more or less prohibited but amethyst may still be found if one is willing to shift tonnes of overburden.

541 - 1000 Ma
|Neoproterozoic intrusive and metamorphic terranes|
Age: Neoproterozoic (541 - 1000 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
