THE REPORT IS DUE Tuesday, October 1 .

No LATE Reports Please. The Figures High-quality, neat and informative computer-generated diagrams are required for this report. All figures should have a specific figure number so that they can be referred to in your discussion. The figures should be numbered in the order in which they are discussed in the text.

Here is a list of diagrams you could use:

A location map showing where Lessors Quarry is in Vermont. Try downloading one off the web.

Your basemap of quarry floor including all of your survey. It must have a bar scale, north arrow, title, with authors, figure caption, key etc. It should also include the locations of your cross sections and plotted bedding plane data (strikes and dips).

Integrated cross section looking north. This diagram will have the south wall projected beneath the north wall in the position dictated by your map of the quarry floor and the measurements taken along the east wall by the class. It must be at the same scale as the quarry floor map. It must have a bar scale, labels for geological features (All faults, cleavages, bedding planes, folds, veins and location of detailed sketches of crosscutting relationships). Each feature should be labeled using letters, numbers, or a coordinate system of your choosing. The diagram will need a title, figure caption, and explanation (if needed). This diagram is the major object of the project since you can base much of your summary discussion of structural history on this figure.

Stratigraphic column. Again with proper and complete labels, figure caption etc. Make sure you take into account our suggestions.

Detailed sketches: The number and character is up to each team/individual. Here are some possibilities:

Cleavage showing geometry and relation to adjacent bedding and fossils and faults.

Offset of bedding as a function of the angle between bedding and cleavage, truncation of fossils.

Characteristics of the fault zone showing calcite, shale layering, slickenlines (linear grooves on fault surfaces), relation to adjacent bedding and cleavage. Arrows showing inferred senses of displacement on all faults.

Details of the synclinal fault. Fault tip (termination) features, 2 generations of cleavage (labeled S1 and S2) within the fault and the inferred senses of displacement. 6. You must come up with a series of diagrams that show the sequential evolution of features (i.e., faults, folds, cleavage) at Lessor's Quarry. These diagrams should be based on your integrated cross section and your observations of cross-cutting relationships. The first figure should have horizontal bedding planes.

The last figure of your series should be identical to your integrated cross section. It's up to you to fill in the blanks and provide evidence for your choices. We will be working onthis aspect most of next week.

The Written Report

The purpose of this report is to document the complete geological evolution of Lessors Quarry. Pay close attention to the comments written on your essays of the environment of deposition. Font size cannot be smaller than font 10 style Geneva or larger than font 12 Times as examples. Spacing should be 2 or 1.5. Subdivide your report using the titles listed below. Each of the main sections below can be further subdivided into data sections and interpretation sections.

YOU MUST SEPARATE OUT ALL DATA FROM THE INTERPRETATION OF THE DATA.

This is the most important aspect of the report. Here is an outline of the subsections and content that I suggest.

INTRODUCTION.

Includes location of study, purpose of the study (i.e. the questions you will try to answer and why they are significant, and a brief summary of the organization of the report. Be as specific as you can. No more than 2 paragraphs.

STRATIGRAPHY.

Discussion should be short (Less than 1 page) and based on your stratigraphic column. First the facts, which should be shown in your stratigraphic column) then the interpretation of the environment of deposition. Consider only the most likely hypothesis that is supported by your observations. Refer to your figures. Consider dividing this into the following subsections: Data Presentation, Data Interpretation.

STRUCTURAL FEATURES.

This part should be divided into 4 subsections: A. Structure of the Quarry. Start by discussing the orientation of bedding planes around the quarry. Refer to your basemaps and your structure sections as figures. Then discuss the location and orientation of the main features: Faults, Folds, Cleavages, Bedding Planes, Veins. B. Cleavage. Divided into 2 parts. 1. Data and 2. Interpretation (Limits your interpretation to 2 hypotheses only: Displacements parallel to the cleavage vs. displacement perpendicular to the cleavage. Origin of cleavage and how you know (e.g., pressure solution processes that formed the cleavage planes). Are their different types? C. Fault and Fold Characteristics. State the facts then your interpretations. Facts: Describe Lessor's Quarry Fault and the Stanley Fault and all features that define it as a fault (i.e. how you know it is a fault and not a fracture). Interpretation: Present a discussion of the Lessor's Quarry fault on the north wall of the quarry. How is it identified, what features characterize the fault? What features determine its direction of displacement. Discuss the Stanley fault and associated fold(s). How do these structures affect the structures on the north wall? What is the displacement sense and how do you know? Facts: Synclinal Fault Interpretation: Displacement during each stage of development. Describe its characteristics and discuss its age relative to the syncline. Cite evidence. (No more than 2 pages excluding well labelled diagrams )

SYNTHESIS.

This section combines all of your observations and interpretations into a one to two page discussion of the evolution of the structures at Lessor's Quarry. This essay should refer to the set of illustrations that depict the evolution. Feel free to refer to any other figure that shows evidence upon which you are basing your explanations or hypotheses. The full cross section also would be very helpful here. A. Discussion of the geometry of the faults and why some are folded and others are not. How do your observations compare with those predicted from the FAULT-BEND FOLD models? B. Chronological development of the faults and folds. C. Relation of cleavage to the faults. When did the cleavage form, before, after, during etc. REFERENCES CITED. Include references of any material you used in preparing your report and diagrams. REMEMBER, THE REPORTS MUST BE DONE INDIVIDUALLY. AVOID PLAGIARISM. FEEL FREE TO REFERENCE THE WORK OR IDEAS OF OTHER MEMBERS OF THE CLASS. YOU DO NOT HAVE TO REFERENCE COREY OR I. IF YOU USE INFORMATION FROM PUBLISHED SOURCES OR ON THE WEB IT ALSO MUST BE REFERENCED
