5. (7 pts) Make a list of formations from oldest to youngest. Which geologic laws/principles did you use to prepare your list? 6. (1 pt) There is a fault in the map area. Which side of the fault is upthrown relative to the other side? Mark this on your map. 7. (1 pt) The fault plane for this normal fault dips in which direction? 8. (2 pts) Note the scale of the map. What is the distance in metres between point Y and point Z? What is the distance in metres between point A and point B? 9. (15 pts) Prepare a cross-section through the map from position Y to Z (Y-Z). 10. (15 pts) Prepare a cross-section through the map from position A to B (A-B). 11. (7 pts) In point form, describe the geological history of the map area. N ZA Wavy Wastelands Geological Map 60° B /60° 15° (60° 60° (60° 60° Legend (not in order) Conglomerate Limestone Sandstone Mudstone 1 Mudstone 2 Sandy Shale Siltstone Shale Lava Flow Shaley Limestone Flat topography Scale: 1:10,000 8-E5 EXERCISES - COMPLEX GEOLOGICAL MAPS & CROSS-SECTIONS The following geological map exercise will give you practice with constructing geological cross- sections for more complex mapping areas. The mapping area in this exercise is flat; there is no topography (and thus no contour lines). Note: you will need to hand in your map along with the cross-sections you prepare in this exercise. Map: Wavy Wastelands 1. (2 pts) Examine the map of the Wavy Wastelands. Refer to the map legend. Note that the rock types are not presented in order of age in the legend - this is one of the things you will determine in this lab. What kind of rocks are found in this map area: sedimentary, igneous, and/or metamorphic? How many units can you see? 2. (2 pts) Note the strike and dip symbol on the map. Which direction are the units striking and dipping? Do the strike and dip of the beds change at all as you move across the map area? 3. (2 pts) There is a major unconformity in the map area: what kind of unconformity is it? Outline the trace of the unconformity in red on your map. 4. (2 pts) Draw fold axial traces on the map for the folds in the map area (there should be six). Indicate whether the folds are anticlines or synclines by putting the appropriate symbols on the map for each fold. Note that all the folds are plunging in the same direction.
