Culnafay ASSI contains unique diatomite and associated materials deposited on historically (7500-5000yrs BP approx) seasonally innundated ground with the transition from diatomite to glacial still marking the former shoreline.
This is the largest good quality deposit remaining in the area and is amongst the most important post-glacial freshwater diatomite deposits in the world. Diatomite is of international importance for biological, geological, hydrological and climatological reasons and it has considerable archaeological significance.
