Structural Geology

The geological map in Figure 6 shows an outcrop pattern of five strata on a flatlandscape.

a) Sketch a cross section from A to B. Indicate with question marks where thee xtent of a layer is not known. Use the box below the map for your sketch, take a photo and insert it into the answer document of the exam. If you have no printer, use a 10 cm x 4 cm rectangle.(8 marks)

b) List the sequence of rock types found in boreholes at points X and Y from the ground surface until no further information can be deducted from the map.

Structural Geology

A large civil engineering project is to be conducted in an area where the ground is mainly dominated by limestone. Briefly describe the parameters that need to be considered to assess the rock mass quality of the Limestone . Comment on the influence of each of these parameters on the rock mass.

Structural Geology

the three different situations.Assuming that the rocks in each picture have similar mechanical properties at 20°C and atmospheric pressure, what can you say about the temperature and pressure during deformation?(10 marks)

Structural Geology

The sandstone cliff at a coastal location (top part of Figure 4) is well known for its instability and cliff erosion. What type of mass movement may be expected here?Give reasons for your answer.(6 marks)

Structural Geology

Identify the rock samples A and B shown in Figure 3. Compare and contrast the two rock samples in terms of their formation and engineering properties. How can these rocks be used by engineers and what problems can we expect?

Structural Geology

We looked at five geologic units (formations) that may be found in the Chico area. These units represent all three rock types (Igneous, sedimentary, metamorphic).

Structural Geology

The Tapeats Sandstone is foliated.

True

False

Structural Geology

In sedimentary rocks, Cliff Forming layers are

d. Are often composed of loose and unconsolidated material

b. Contain a greater frequency of rounded clasts

C. Often harder and more resistant to erosion

a. Mainly composed of fine-grained clasts

Structural Geology

In our field trips, we looked at and describe two diffferent sedimentary depositional environments within the Tuscan Formation. Name both environments.

Structural Geology

In the virtual field trip "The mystery of Black Canyon", the mystery centers around an unconformity. Explain two lines of evidence that support the existence of the unconformity.
