A small stream of geological importance in S Moray, the Marl Burn rises on slopes to the southwest of Carn Bad a' Ghuail, on the border with Aberdeenshire, and flows south for barely a half-mile (0.8 km) to fall into the River Avon a quarter-mile (0.5 km) northwest of Inchrory. The stream is unnamed on Ordnance Survey maps, but a 6-m / 20-foot thick tufa deposit at its mouth has formed from the precipitation of calcium carbonate which was dissolved from local limestone. This is a unique deposit in Scotland and contains fossil molluscs, while charcoal in soil horizons within the deposit have enabled it to be dated to 7400 years ago. These deposits form part of the Inchrory Site of Special Scientific Interest (SSSI).
