Diploma thesis: Tephrostratigraphic studies on a sediment core from Lake Prespa in the Balkans.”

  • The diploma thesis was carried out at the Dipartimento di Scienze della Terra, University of Pisa, Italy under the supervision of Bernd Wagner, Giovanni Zanchetta and Roberto Sulpizio. The overall aim of the thesis was to build a detailed tephrostratigraphic record of Lake Prespa, Balkans to reconstruct its paleoenvironmental and paleoclimatic history. Distal tephra layers represent individual time marker horizons in the sediments, which have been used to establish an independent event stratigraphy. Further, tephrostratigraphic work provided important information about ash dispersal and explosion patterns of Italian source volcanoes.

Mapping thesis: “Geological mapping of the southern region of Namakkal, Tamil Nadu, India.”

  • The mapping thesis forms part of the final diploma and was carried out in cooperation with the Department of Geological Science, University of Jadavpur, Kolkata, India. During a geological mapping survey at the scale of 1:10 000 metamorphic rock-series of the southern region of Namakkal were structurally and petrographically analysed in order to reconstruct the Precambrian crustal evolution of Peninsular India.

PhD Research

Title:

“High precision tephrochronology: Tracking the time-varying pulse of Mt Taranaki, North Island, New Zealand.”

Research objectives

Tephrochronology has become an important tool in volcanological studies in New Zealand. Tephra layers not only reveal the volcanic eruption history of source volcanoes but also provide an unprecedented view into the time-varying dynamics of volcanoes and their magmatic systems, including any changes in frequency, magnitude and/or geochemical composition.

The overall aim of my research is to produce a detailed tephrochronological framework of andesitic stratovolcano Mt Taranaki by investigating several sediment cores from lakes and swamps in the near-vent area. Considering that the rhyolitic tephra record in New Zealand is reasonably well established, tephro-stratigraphic and -chronological studies of andesitic tephra are still in their infancy due to the more restricted distribution of andesitic tephra, the ease with which those weather and their complex fingerprinting. Hence, the technical challenge during my research will include the development of new correlation tools based on physical, geochemical and petrological properties of andesitic tephra, in conjunction with precise age determinations and associated statistical matching techniques. Further, by building a more precise time‐controlled eruption record I can provide the key to strengthening probabilistic hazard forecasting at Mt Taranaki.
