Petrology Field Trip

April 22-24, 2005

During the weeks prior to the field trip you have examined a suite of about 27 rocks from the Grenville Province in your laboratory.  These samples were collected in Canada and are indexed to specific field trip stops.  Data from these rocks (rock name, principal minerals, degree of metamorphism or type of igneous activity, structures, protolith, etc.) should be entered into your field books before we start the trip.  Leave space in your field books for new data, sketches, corrections, etc.

At each stop you will examine the exposures at outcrop scale and examine individual hand samples of your selection using the hand lens.  Compare your field data with the laboratory data and make appropriate entries, additions and corrections in your notebooks.  At some stops you will be asked to perform some specific exercises, make some observations, measure some features, or draw a sketch of an exposure with a geologic interpretation.  On the field trip map you should note your data as we move through the area with the goal of constructing a geologic map of the area encompassed by the trip route. In this regard, colored pencils (and possibly tracing paper) would be useful.

Your field trip report will be submitted to your Teaching Assistant in our regular class on Friday (April 29), the week following the trip.  It should include: 1) your notebooks (with both laboratory and field data), 2) your geologic map, 3) results of the prescribed field trip exercises (recorded in the notebook), and 4) a short (two page or less) summary of the geology of the field trip area as revealed in the lab and in the field in the context our your understanding of the Grenville Province of Canada.
