Seafloor Magmatic Construction - A LA ICPMS Based Study

University Of Houston, Houston TX

Investigators

Abstract

Under this funding, the PI will use in situ analyses of minerals from both extrusive and intrusive rocks (collected from the Mid-Atlantic Ridge near the Kane Transform Fault and the Southwest Indian Ridge near the Atlantis II Fracture zone) to understand magmatic construction processes. Data will be collected using Laser-Ablation Inductively-Coupled-Plasma Mass- Spectrometry (LA ICPMS). This study will provide insight into the magmatic system over three different spatial scales and will test a number of ideas regarding the petrogenesis of deep crustal rocks, how they were emplaced, how they crystallized, and under what physical conditions.
