Marinova dolostone quarry is a quarry in a mineral deposit situated on a dolostone deposit of Pskov formation with a thickness of about ten metres in Võru County, Meremäe rural municipality in Estonia.
The dolostone above groundwater level is characterised by strong crushing and the crumbling of the upper part of the deposit.
The nearby Belka River valley has aided the water running between the cracked rocks and therefore, the formation of extensive karst phenomena.
There are numerous springs on the west slope of the valley that feed from the water traversing Marinova quarry dolostones.
The tectonic processes could have had a crushing influence on the open dolostones in the Marinova quarry.
