Stratigraphy of sediments from the Håkon Mosby Mud Volcano Area

Abstract

 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.
