Lab Assignment: Petrogenesis of the McNutt Volcanic Complex

The McNutt Volcanic Complex consists of a series of 2.0 Ma lava flows erupted onto approximately 40 km thick, Proterozoic (ca. 1.1 Ga) continental crust of the Rolla Basement Terrane. From the mineralogy, major element, trace element, and isotopic data for the McNutt lavas and Rolla Basement Terrane, fully describe the McNutt lavas and their petrogenesis.

I request that you work on this lab project on your own. A written report of your findings, following the Journal of Petrology format, is due on April 16th, 1999 before 5:00 pm. Late Penalty will be 10% per day. There will be a thirty page maximum (including text, bibliography, and figures) limit on your report. The following week during class (April 20th and 22nd) you will be requested to give a 20 minute oral presentations of your findings, with 10 minutes reserved for open discussion and debate by the class. The order of presentation will be decided by draw (high card chooses first, and so on down to the low card). Therefore, everyone should be prepared to give their oral presentation on April 20th. This lab is worth 40% of your final grade, and the written and oral presentations will be weighted equally during assessment.
