Earth Science Short Field Based Investigation
This scientific report will explain what the primary data that was collected on our field trip to Coomera and Springwood Quarries represents. On the field trip we were given an observation journal to record primary data about the two types of rocks, at Coomera (Nucrush Quarry) and at Springwood Conservation Park. To maintain an equal representation, secondary data will be used to refer to the main points.
On our field trip, we went to Nucrush Quarry at Coomera. Nucrush offer a range of products that are all made from a sedimentary rock by the name of, Greywacke.
Figure 1: The Rock Cycle
According to figure 1, greywacke is formed deep under the sea. The sediments, known as sand, are then mixed …show more content…
These sediments are then deposited in a river, where the next stage of formation occurs. The next stage in the formation of conglomerate is the cementing and compaction of the sediments. During this process, pressure compacts the sediments together which is then cemented together to form the sedimentary rock. This area at Springwood was quarried for its major deposit of conglomerate. The rock face at Springwood has a gabion wall, in order to protect visitors from getting hit by falling rocks. The gabion wall is made out of the Hornfels from the quarry at Mt. Coot-Tha. Figure 2: Similarities between Greywacke and Conglomerate.
A comparison can be made using the two stations and their rock products, the following table shows what similarities can be made from the data given from the field-trip. This table shows the similarities between the Coomera and Springwood Quarries. It displays that you are able to see the exposed rock faces at the sites. It shows the areas at the quarries had waterways in the vicinity.
A table of the differences between the rocks at the Coomera and Springwood quarries. This was done, using the primary data that was collected on the field trip, to make judgements of these two quarries. The table that was then produced from this primary data is as
