High level sill and dyke intrusions initiated from rapidly buried mafic lava flows in scoria cones of Tongoa, Vanuatu (New Hebrides), South Pacific
(Massey University., 2006-01-01)
Scoria cones are generally considered to grow rapidly in days to weeks or months. During their growth lava flows may be fed onto the cone surface from lava-lake breaches, or form by coalescence of spatter; such flows are ...

Magnetic characteristics of the Ság-hegy volcanic complex, little Hungarian Plain
(Massey University., 2006-01-01)
The Ság-hegy volcanic complex is located in the little Hungarian Plain Volcanic Field (LHPVF). An 39Ar/ 40Ar geochronolgy gave an isochron age of 5,42 ±0,06 My for the Ság- hegy (Wijbrans et al. 2004). Evolution of the ...
Exploding lakes in Vanuatu - "Surtseyan-style" eruptions witnessed on Ambae Island
(Massey University, 2006-01-01)
After a long silence, Lake Vui on Ambae Island burst into spectacular life on the 28th of November 2005, disrupting the lives of 10 000 inhabitants on this sleepy tropical island in the SW Pacific. "Surtseyan- style" ...
Syn- and post-eruptive erosion, gully formation, and morphological evolution of a tephra ring in tropical climate erupted in 1913 in West Ambrym, Vanuatu
(Massey University., 2006-01-01)
Syn- and post-eruptive erosion of volcanic cones plays an important role in mass redistribution of tephra over short periods. Descriptions of the early stages of erosion of tephra from monogenetic volcanic cones are rare, ...

Influence of titanomagnetite composition on the magnetic anisotropy in a dyke-sill complex in Hungary
(Massey University., 2006-01-01)
In the last decades low-field magnetic susceptibility measurements have become an increasingly attractive method for geological studies which use the scalar values (bulk susceptibility) as well as the directional information, ...
Peperites and soft sediment deformation textures of a shallow subaqueous Miocene rhyolitic cryptodome and dyke complex, Pálháza, Hungary
(Massey University., 2006-01-01)
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 ...
Lava lakes and shallow level magmatic feeding systems of mafic volcanoes of an ocean island: Ambrym, Vanuatu (New Hebrides), South Pacific
(Massey University., 2006-01-01)
Ambrym is an active volcanic island with 2 major vent complexes; Marum and Benbow. These vent complexes are continuously active over at least the past two thousands of years. These active vents either produce constant ...
