ASSIGNMENT QUESTIONS

Your assignment should include answers to all parts of Questions 1-3 below:

QUESTION ONE - GEOLOGICAL MAPPING ("UPPHILLA DOWNS")

Examine the map on the next page and identify the axis of the fold. For this exercise assume that the
fold has a simple or smooth and regular shape.

(a) What is the oldest, and what is the youngest of the rock on the map?

Oldest:

Youngest

(b) What kind of fold is represented on the map?

(c) Draw a geological cross section along the line A-B shown on the map.

Provide this on a separate sheet. Draw the cross section to a depth of -300 m.

Note that the scale of the map is 1cm = 100 m (and that the scale bar can be stretched or shrunk by your printer). Your cross-sections should be drawn with the same horizontal and vertical scale (VE = VS/HS = 1; note: VE stands for Vertical Exaggeration).

(d) Provide a brief summary of the geological events evident in the map and your cross-section (dot
points is fine).

QUESTION TWO - GEOLOGICAL MAPPING ("DOUBTFUL VALLEY")

Examine the relationship between topography (as shown by the contour lines), stratigraphy (sedimentary/volcanic rock sequence), and the dolerite dykes in the map on the next page.

(a) What kind of fault is represented on the map?

(b) What is the orientation of the fault plane?

(c) Determine the components of the fault movement, i.e. work out the dip-slip, strike-slip, net-slip,
heave and throw

(d) Draw a geological cross section along the line C-D shown on the map.

Provide this on a separate sheet.

Note that the scale of the map is 1cm = 100 m (and that the scale bar can be stretched or shrunk by your printer). Your cross-sections should be drawn with the same horizontal and vertical scale (VE = VS/HS = 1; note: VE stands for Vertical Exaggeration).

(e) Provide a brief summary of the geological events evident in the map and your cross-section (dot points is fine).

Map excerise five: The geology of Doubtful Valley

QUESTION THREE - SEDIMENTARY ROCK DESCRIPTION

Provide a description and name the sedimentary rock sample below. Include a likely environment the rock formed in, including the energy level.

You should look at the colour images online and use the zoom function to aid with your observations. The sample is approximately 12 cm in length. You may wish to include the rock image below with annotations to highlight what features you are describing.
