Question
Put these things in their proper order, from youngest at the top to oldest at the bottom, using the principles of relative dating. Youngest Muav Limestone Bright Angol Shale Tapeats Sandstone GRAND CANYON INNER GORGE Vishau Schist Zoroaster Granite Oldest The unconformity between M and K is a/an The unconformity between I and A, B, C & D is a/an Layer M has inclusions of K. Could it also have inclusions of J? Could M have inclusions of F? Or could F have inclusions of M? Now that you're an expert, try another relative dating exercise on the reverse side! It's a little bit more complicated, but you can handle it.Explanation / Answer
1.By careful observation of the given map, following events are observed from older(1) to younger (9) :
9. Deposition of I, H, G.
8. Again erosional surface (Angular unconfomity)
7. Tilting of M, E, L, D, C, B, A and the intrusion
6. Deposition of L, D, C, B, A
5. Intrusion of F (igneous sill)
4. Deposition of M,E.
3. Erosional surface
2. Intrusion of J
1. Deposition of K
2. The unconformity between M and K is a nonconformity. Because the lower bed is a metamorphic rock (schist) and the upper bed of erosional surface is a sedimentary bed (gravel).
3. The unconfomity between I and A, B, C, D is an angular unconformity as the lower beds A, B, C, D are tilted and upper I bed is horizontal.
4. Yes, it could have been possible to get J inclusion within M bed as J is intruded along K bed.
