Overview
Topic status: In progress
Andesite is one of the most abundant magma types erupted globally and this convergent-margin magmatism is essential for the differentiation of silicate Earth and growth of the continental crust. However, there continues to be a confusing array of different models to explain both its origin and its exceptional abundance at convergent margins. This research project is to undertake a literature review, construct and analyse a database, and carry out a sample study of andesites, to shed light on the mechanisms of their formation. This work can preface an Honours/MSc research project in 2012.
Research activities
This project will involve literature collation and examination to build up a database (e.g., excel spreadsheet) on andesites, capturing petrological, geochemical and tectonic information so that whole-rock chemical data are better calibrated against petrological data. Samples previously collected by the supervisory team can also be examined in thin-section, for petrographic information. The project will be an opportunity for a student to improve their petrological and geochemical skills.
Expected outcomes
Expected scientific outcomes include new information and distinguishing characteristics of the different types of andesites, from which petrologic-tectonic pathways can be identified. Expected outcomes for the student include improved skills in the critical analysis of scientific literature; database design, construction and interrogation; and opportunities to further develop their petrological and geochemical expertise and international connections.
