1. Geomath Geology 351 - Final Review - Part 2 tom.h.wilson tom.wilson@mail.wvu.edu Dept. Geology and Geography West Virginia University

2. Integrals Integration Review the problems in the text and homework. 1. Volume of Mt. Fuji; where

3. li lf 2. Determination of the true or total natural strain evaluated from some initial pre-deformed state to some final deformed state in a series of infinitesimal contractions or extensions occurring over a long time period. Evaluate

4. We can simplify the problem and still obtain a useful result. Approximate the average densities 11,000 kg/m3 4,500 kg/m3 3. Be able to integrate the discontinuous function used to approximate internal density contrast and mass distribution within the Earth’s interior. Be able to describe what the above integral represents and how the mass is being calculated; i.e. be able to discuss the geometry of the problem.

5. 4. Heat flow problems surrounding the basic definition Be able to calculate the total heat generated in a given volume by an object with a specified heat generation rate.

6. 5. Understand problems 9.9 and 9.10. Refer to your notes from Tuesday’s class Discussions of problems 1 through 4 are found in the text with additional material presented in class slides. See http://www.geo.wvu.edu/~wilson/geomath/FinalReview-P1.pdf

7. highest =N69W ~625’ 3500 4000 3000 2500 3500 3000 lowest 2500 2000 Now, how would you calculate the dip? 100 feet

8. In the preceding slide we showed that the horizontal distance in the dip direction between control points subsurface formation depths relative to sea level of 2000 and 4000 feet is ~625 feet ~73 2000’ 625’

9. Actual thickness = ? 100’ What is this angle? =73o If the thickness of a dipping bed intersected by a vertical well is 100’, what is the actual bed-normal thickness of the layer? 

10. T, the actual thickness? Apparent thickness 100’ =17o

11. A look at some select problems from the review sheet handed out in class Tuesday 1. What is S at t=0, , and 2 You can get a good sense of the shape of this curve just by plotting up these three values

12. Evaluating sedimentation rate: taking the derivative For =30My and Smax=2.5km

13. 2. Substitute in for the constant terms

14. Salinity Variations
