Tips

GB: In the lower Mirrose Well Cove one finds deposits with repeated sequences. In each sequence, a gradation of the layers can be observed, with the grain size decreasing from the bottom to the top. In the case of Mirrose Well Cove, coarser greywackes were deposited first, turning into fine greywackes, and followed by clayey layers. Altogether, the deposits reach a thickness of six to ten feet (2-3 m). This type of deposit is caused by turbidites (massive mud flows). To trigger a turbidite, minimal vibrations or the deposition of further sediment grains are enough. The sediments then flow down the slope in a turbulent stream along the water current - a slope inclination of 2-3° is enough here - and spread out into the deep sea in the form of a fan. In this way, sediments with a thickness of several dozens of feet can form within a few hours.

EN: Lower Mirrose Well Cove contains deposits with repeated sequences. In each sequence, a gradation of the layers can be observed, with the grain size decreasing from bottom to top. In the case of Mirrose Well Cove, coarser greywackes were first deposited, which transitioned into fine greywackes, followed by clayey layers. Overall, the deposits reach a thickness of two to three meters. These types of deposits are due to turbidites (powerful turbidity currents). To trigger a turbidite, minimal vibrations or the deposition of further sediment grains are sufficient. The sediments then flow down the slope in a turbulent stream with the water current - here a slope of 2-3° is sufficient - and spread out in the deep sea in the form of a fan. In this way, deposits several tens of meters thick can form within a few hours.
