2. Draw lithologic correlation lines to connect equivalent rock units (shown using Roman numerals) in Figure 4.11.<\/p>\r\n
3. Using a different colour, draw lines connecting equivalent time-stratigraphic units. The numbers beside the rock units correspond to time intervals.\u00a0<\/strong><\/span><\/p>\r\n 4. Answer the questions that follow Figure 4.11.<\/p>\r\n \r\n\r\n[caption id=\"attachment_442\" align=\"alignnone\" width=\"1225\"] a. Not all the conglomerates are the same age. How could this occur?<\/p>\r\n b. In what direction is the sourceland for the lower sandstone layer?<\/p>\r\n c. What happens to the thickness of the shale layer from east to west? Considering your answer from (b)<\/em> above, how do you explain this?<\/p>\r\n d. Why is stratigraphic log A thinner than log G even though it represents a longer stratigraphic time interval?<\/p>\r\n e. In log A, between which two time periods was the rate of sedimentation the greatest?<\/p>\r\n f. In which log (A-H) was the rate of sedimentation the greatest?<\/p>\r\n g. What is happening to water depth from time interval 1 to 6?<\/p>\r\n h.
