Stratigraphy of sediments from the Håkon Mosby Mud Volcano Area

Studies of four gravity cores from the Håkon Mosby Mud Volcano area have shown the existence of three lithologic–stratigraphic units: I – brown clay (0–10 ka), II – gray clay (10–30 ka) and III – gray silt (30–61 ka). The units reflect different paleographic sedimentation and conditions, including the influence of mud volcanic activity. Two periods of mud volcanic activity can probably be discerned: 10–30 ka and Recent. The coexistence of Pleistocene and Late Pliocene benthic foraminifera suggests that the source depth of the volcano is located below the Pliocene–Pleistocene boundary.
