Fluorine and Chlorine in Alkaline Magmas |
|
This is a collaborative project with Dr. Norman Charnley, University of Oxford. We are using the electron microprobe at Oxford to determine the fluorine and chlorine content of micas, amphiboles, apatites, and titanites from various alkaline provinces. To date we have studied the Monteregian Hills, Quebec (Canada) and White Mountain, New Hampshire (USA) alkaline provinces, the Beemerville alkaline complex, New Jersey (USA), the Arkansas Alkaline Province, Arkansas (USA), the Archean A-type granites of the Kola Peninsula (Russia), and the Chilwa province (Malawi). Preliminary analysis has indicated a complex relationship between the evolution of the magmatic systems, the sources, and the presence/absence of other halogen-containing minerals. We are in the early stages of data analysis. As results and models are developed they will appear on this page and in the literature. |
