These vent complexes are continuously active over at least the past two thousands of years. These active vents either produce constant degassing during quite periods or sub-Plinian to Vulcanian explosive eruptions commonly influenced by magma-water interaction triggered phreatomagmatic explosive phases. The active vents of Ambrym perfectly expos inner walls of the crater/conduit transition zone, allowing to study in cross sectional view of the interbedded coherent magmatic bodies with pyroclastic successions. In the inner crater/conduit wall of the Marum volcano, that consists of at least 3 major vents, as well as a vent that is located on its flank (Niri Taten) exposes solidified complex lava lake cross-sections, lava spatter cone feeding lava pods, shallow intrusions as well as large sills that connected through a complex network of pathways to the surface and/or into the pyroclastic edifice of the volcano. This suggests that shallow level infiltration of melt into a mafic volcano plays an important role in the edifice growth.Item Peperites and soft sediment deformation textures of a shallow subaqueous Miocene rhyolitic cryptodome and dyke complex, Pálháza, Hungary(Massey University., 2006-01-01) Nemeth, Karoly; Pecskay, Zoltan; Martin, Ulrike; Gmeling, Katalin; Molnar, Ferenc; Cronin, Shane J.Miocene rhyolitic shallow intrusions, cryptodomes and domes emplaced into soft, wet sediment in shallow subaqueous environment form a large intrusive complex in the NE side of the Tokaj Mts. at Pálháza in NE-Hungary. The intrusive complex show interaction textures with the host sediment where blocky peperites formed in a dm-scale, however, irregular contacts closely resembling globular mega-peperites are prominent in the tens of metres scale. The more than 200 m thick succession of intrusive complex interpreted to be a generally steadily growing shallow dyke, cryptodome, and dome complex in a shallow subaqueous environment, similar to those reported from Ponza, Italy.
