Adam Koster

Goals for MS program:

My goals for this program are to gain a better understanding of geology and the techniques involved in analyzing geologic materials. I am specifically interested in getting a better understanding of volcanology. Furthermore, I would like to attain more skill and knowledge of analytical techniques such as: petrography, x-ray diffraction, Scanning electron microscopy, and ICP-MS. Having these skills will help me in achieving my eventual goal of attaining a Ph.D.

Research project:

I will be studying the geochemistry and petrology of a portion of the Los Tuxtlas Volcanic Field which is in southern Veracruz, Mexico. My research will be aimed at gaining a better understanding of the magmatic plumbing system beneath the field. To this end I will be using geographic information systems, petrography (point counting), X-ray fluorescence, X-ray diffraction, ICP-MS, and other analytical methods.
