dc.description.abstractThis study examines methods to determine magma flow direction(s) during emplacement of the Jurassic Ferrar Dolerite intrusions in Antarctica. A brief description is given of the techniques used to determine magma flow directions in sheet intrusions, and an explanation of how, from these observations, magma sources for dike swarms can be located. I discuss how to apply these types of data to try and determine the magma source for Jurassic sheet intrusions in Antarctica. I will present three different emplacement models for the linear intrusive belt found within the Transantarctic Mountains. The models include a linear zone of intrusions that could be produced by back-arc spreading related to subduction, a single intrusive source, and multiple magma sources. Magma flow directions predicted by these models are discussed. A possible test of these models from intrusion orientations in the Skelton Neve region is examined.en
