What To Do<\/h1>\r\n

1. Download the printer-friendly worksheets in the format of your choice (available at the beginning of Lab 4<\/a>). You can also click here<\/a> to download Figure 4.9 as a PNG file for editing with drawing software.<\/p>\r\n

2. Draw lithostratigraphic correlation lines between the rock units A, B, and C in Figure 4.9. Use solid lines for correlations you are confident about and dashed lines for ones that are tentative.<\/p>\r\n

3. Draw lines to correlate any unconformities and label them with their type.<\/p>\r\n

4. Answer the questions that follow Figure 4.9.<\/p>\r\n\r\n\r\n[caption id=\"attachment_425\" align=\"aligncenter\" width=\"605\"]\"\"<\/a> Figure 4.9 |<\/strong> Stratigraphic columns for Exercise 4.1.[\/caption]\r\n

Questions<\/h3>\r\n

a. Were units A, B and C deposited in terrestrial or marine environments?<\/p>\r\n

b. Locate the unconformity at the bottom of units B and C and draw a dark wiggly line at its location. Name the type of unconformity at the bottom of units B and C.<\/p>\r\n

c. What happens to the conglomerate from east to west?<\/p>\r\n

d. In which direction was the source of sediments for the conglomerate?<\/p>\r\n

e. What happens to the middle sandstone unit between B and C?<\/p>\r\n

f. What depositional environment created the middle sandstone and siltstone sequence?<\/p>\r\n

g. What type of regional scale unconformity could occur below the debris flow deposit?<\/p>\r\n

h. The debris flow deposit could also be just a local process where a coarse-grained alluvial fan advanced over the sedimentary environment you identified in (g)<\/em>. What other information would you need to decide which of these two options (regional erosion, local erosion) is correct?<\/p>","rendered":"
