Worked Solution & Example Answer:Analyse the relationship between mineral mining sites and rock types shown in Figure 9 - AQA - A-Level Geography - Question 5 - 2020 - Paper 2
Step 1
Analysis of distribution of minerals
Answer
Figure 9 illustrates that mineral deposits are not evenly distributed across the Lake District. Notably, these minerals tend to cluster in specific areas, with a significant concentration found around the region near Cleator, and another cluster extending from the north down towards the south of the district, particularly around the site of Carrock Edge, which is part of the Borrowdale Volcanics geological formation.
Step 2
Connection to geological formations
Answer
The mining sites shown correspond significantly to the underlying rock types. For instance, areas rich in graphite are situated in proximity to the Skiddaw Group, which consists of mainly metamorphic rocks. In contrast, minerals such as copper and zinc, which are more frequently mined, can be found in regions associated with carboniferous sedimentary rocks.
Step 3
Variability in mineral types and locations
Answer
Figure 9 provides insight into the variance in the types and quantities of minerals present across different rock groups. For example, copper is found in significant quantities at multiple locations, while minerals like barium are notably limited, discovered in only a few specific sites. The predominance of certain minerals in particular geological settings highlights the close relationship between the mineral resources and their respective rock types.
Step 4
Conclusion on geological influences
Answer
In conclusion, the distribution of mineral mining sites in the Lake District is closely influenced by geological factors. The geological history and rock type distribution dictate the location of mineral deposits, demonstrating why certain areas are more mineral-rich than others, with the Skiddaw Group playing a pivotal role in this distribution.
