GEOL 342 - Field trip paper/presentation team project:
The Plan: On Saturday, 11/4, teams of students will be assigned to four different road-cut outcrops on Corridor H between Wardensville and Moorefield WV. Each team will spend several hours at the outcrop, studying it and collecting data. By the end of the afternoon, each team should have collected sufficient data to:
- Present a measured section of several meters of section, noting for each bed:
- Sedimentary structures
- Presence or absence (and if possible, identity) of fossils
- Obvious erosional surfaces or truncation by faults
- Note significant instances of the above information for beds not included in the measured section
- Describe the structure of the outcrop (anticlines, synclines, faults, etc.)
- Present any other data of interest
Deliverables: Each team is to collaborate o the development of the following:
- A 10 - 15 minute PowerPoint presentation to be delivered in lecture on 12/8/17.
- A 10-12 page paper (double spaced, not including measured sections and other appendices) covering the same material as the .ppt., due on the last day of class 12/11/17.
- The location and identifying features of the outcrop you studied (such that a future field trip could locate it.)
- A detailed description of the outcrop
- You interpretation of the depositional environment or environments represented by the outcrop, with justifications
- Your assessment, based on comparison with information in the literature, of the identity of the rock unit represented by the outcrop.
- A discussion of the tectonic and paleogeographic setting of your outcrop.
- Additionally, your paper should provide a brief synopsis of the division of labor among members of your group.
Assessing rock unit identity:Without giving away the store, on-line resources include:
- Geologic map of the Moorefield quadrangle - This is just slightly to the west of our work area, but encompasses most of the rock units we might have encountered (with the exceptions of the Silurian Tuscarora Formation and Ordovician Juniata and Oswego Formations.)
- USGS interactive geologic map of West Virginia. This links directly to USGS descriptions of major rock units mapped, but frequently lacks formation-level resolution.
- Stratigraphy is frequently revised, so different references may refer to the same rocks by different names. Be sure to look for the most recent references.
- Although you may never cite it, Wikipedia is a good place to start developing a bibliography.
- Juniata Formation (Ord)
- Tuscarora Formation (Sil)
- Tonoloway Formation (Sil - Dev)
- Helderberg Group (Dev)
- Oriskany Sandstone (Dev)
- Marcellus Shale (Dev)
- Harrell Shale (Dev)
- Brallier Formation (Dev)
- Scherr Formation (Dev)
- Foreknobs Formation (Dev)
- Hampshire Formation (Dev)
- Pocono Group (Rockwell and Purslane Formations) (Carb)
With your permission, I would like a copy of all Power Point presentations in pdf format to post on the course website. The aim is for GEOL342 students to develop, over the coming years, a full-blown reference to the outcrops of Corridor - H.
This ought to be fun.
