GEY 100 General Instructions for Roadcut Cross Sections
Use the roadcut/cross-section format outlined below as your “canvas” to illustrate the simple basic field relations of the different rocks and structures under study as is typically found in this area of northern New England. Remember that these are not cartoons but a way to display scientific information and understanding with care and precision. The roadcut format is used to provide a familiar and reasonably-scaled perspective on the crustal processes. Refer to your text book for other examples of the typical roadside outcrop and this cross-section vew. FOLLOW THIS EXACT FORMAT!!!
General Instructions:
1. All line work, lettering and patterning using a mechanical pencil or ultrafine marker.
2. Informative title – specify what kinds of rocks or structures are featured in your cross section. General titles like “Sedimentary Rocks in Cross Section” aren’t informative enough.
3. Legend is in “stratigraphic order” in a single stack of square legend boxes arranged with the oldest at bottom and the youngest at the top. Provide rock type names, descriptions and geologic time period ages for rock units appropriate for the geologic history of New England as suggested in assignment instructions.
4. Use a ruler where appropriate for legend boxes, scale bar and the base of the outcrop.
5. Label scale bar in ground distance and specify units appropriate for the roadcut outcrop format of the assignment. Be neat and accurate in drawing and subdividing your scale bar. Don’t provide a conversion for the scale bar such as 1 inch = 10 feet, just label the bar directly.
6. All rocks depicted in the cross sections should have a rock type pattern appropriate for the specific rock types shown, as suggested in instructions as well as a color to enhance the cross section display. Colors and patterns in the outcrop and the legend boxes should match.
8. Add color last using sharpened colored pencils on their side for SHADING ONLY.
Don’t do any line work, lettering or patterning in colored pencils as they are too soft.
Rubric for Grading the Roadcut Outcrop Cross Sections
100 Geologically perfect correct use of symbols, patterns and cross cutting relations;
Presentation neat carefully done and exquisitely colored
95 Geologically near perfect with mostly correct use of patterns and relations; Presentation relatively neat, care taken and beautifully colored
90 Geologically mostly perfect with basic correct use of pattern & relations; Presentation relatively neat, some care taken and carefully colored.
85 Geologically OK, not perfect, but adequate portrayal of geologic relations’
Presentation shows organization adequate care and adequately colored.
80 Geologically OK on basics, some missed concepts;
Presentation shows some organization, some care and some effort in coloring.
75 Geologically missed concepts with some basics OK
Presentation basic format, a bit sloppy, less than adequately colored.
70 Geologically missed most concepts but attempted basics;
Presentation less than adequate, unorganized and sloppy, colors incomplete.
65 Geologically missed nearly all concepts but some attempt.
Presentation seriously lacking organization, careless and messy.
60 Geologically missed all concepts but some redeeming feature;
Presentation sloppy with illegible linework, improper use of patterns or colors.
50 Geologically missed all concepts, and relationships.
Presentation totally unorganized, failed to follow format, lacked patterns,colors.
