4 PM Work on constructing map in Illustrator CS4 Part III Creating Geologic Map Required Elements for Final Geologic Map see attached grading rubric for weighting of each element Map Sheet 11 x 17 page landscape or portrait Geologic Map to include Topographic base Outcrops single color or color coded to map unit Map Units colored and labeled with unit abbreviations e g TF for Thomson Formation Geologic line work contacts and faults qualify as to confidence of location by different line types Structure symbols use different symbols for different structures see http pubs usgs gov of 1999 of99 430 for USGS recommendations for symbols Traverse Lines Cross Section line labeled X X Description of Map Units to include Color box with map unit abbreviation e g TF Map units listed in chronologic order youngest on top Map unit descriptions should summarize the various rock types textures and structures observed throughout the map unit Also describe the contact relationships with the adjacent map units Correlation of Map Units diagram arrange map unit color boxes with labels in proper chronological order Unit that are closely related in origin or timing should touch units with significant time gaps between them should be separated by a space Cross Section draw a single cross section with no vertical exaggeration along an E W line Colorize and label the units the same as in the geologic map No need to qualify the different line types Symbol Legend key to all linework and structure symbols Other Components Title should include geographical references e g Geologic map of the Tamarack Area Swamp County Minnesota Author Affiliation and Date Scale Bar in meters and feet North Arrow and Proportional Scale of map e g 1 10 000 SUGGESTION look at a published geologic maps to get ideas on layout and content Due Date Tuesday May 11th by 5PM What to turn in o Adobe pdf file of your map1 o Arcview shapefiles outcrop traverse structure geo lines geo units 1 o Field notes and Field map2 o Clipboard and any other equipment borrowed for project2 1 Send to Jim mille066 umn edu by email attachment or drop off a jump drive will be returned 2 You can drop these in a box labeled GEOL 3000 in the geology dept office Heller Hall 230 Your map will be printed out on an 11 x 17 sheet of paper The map field map note and your final grading rubric can be picked up from the geology dept office after Friday May 15th GEOL 3000 Spr 2010 Name Map Score 45 pts Grading Rubric for Final Geologic Map General 8 pts Layout Appearance All requested components are shown 3 5 Comments Geologic Map 14 pts

types 2 2 Geologic interpretation reasonable based on lithologies topography outcrop control and structure 6 Comments Description of Map Units 8 pts Map units listed in chronologic order with labeled color box 2 Map unit descriptions adequately summarize the various rock types textures structures and contact relationships observed throughout the map unit 6 Comments Correlation of Map Units 5 pts Map unit boxes with labels arranged in proper chronological order 2 Spacing conveys reasonable inference about genetic relationships between units 3 Comments Cross Section 8 pts Units colored properly and labeled 2 Contacts along section properly located to map 2 Subsurface interpretation reasonable based on lithologies and structure 4 Comments Symbol Legend all linework and structure symbols properly keyed 2 pt 2 Comments
