Eruption and emplacement of the 1.3-Ma Ongatiti Ignimbrite, New Zealand: Regional pathways, particle processes, and pumice evolution associated with a large-volume pyroclastic flow deposit
(The University of Waikato, 2020)Pyroclastic flows are the most devastating phenomena of explosive volcanic eruptions. These hazardous density currents are able to travel several tens of kilometers radially away from their source as fast, hot density ... -
Volcanology and secondary alteration of the 1.6 Ma Ngaroma Ignimbrite, Upper Waipari Valley
(The University of Waikato, 2020)The 1.6 Ma Ngaroma eruption from the Mangakino Volcanic Centre (MVC) is the first known rhyolitic event of the Taupo Volcanic Zone (TVZ), and variations of primary components recorded throughout the Ngaroma Ignimbrite ... -
Volcanic and sedimentary geology of the basaltic Karaka Volcano, South Auckland
(The University of Waikato, 2020)Intraplate monogenetic volcanic fields are a common volcanic feature of the upper western North Island. There are four geographically related fields, approximately 38 km apart which young northwards from Raglan to Auckland. ... -
Characteristics and origin of hydrothermal pebble dykes and associated host rock alteration on the Thames coast, Coromandel Volcanic Zone
(The University of Waikato, 2020)During the Miocene to early Pliocene (c. 18 Ma to 2 Ma), subduction-related volcanism migrated down the Coromandel Peninsula forming the Coromandel Volcanic Zone. This period resulted in the development of extensive ... -
Precursory eruptions, magma priming and eruption dynamics associated with the climactic 19th February 1975 eruption of Ngauruhoe
(The University of Waikato, 2019)Ngauruhoe is an active central North Island composite volcano, located at the south end of the Taupo Volcanic Zone. This basaltic andesite to andesite cone is one of the most active vents of the larger Tongariro Volcanic ...
