Using information available from the map, lectures and the internet, answer the following questions. On the digital map above, use the digital zoom controls that are provided in the map itself (+/- signs on the inset map) or zoom using your mouse, but avoid screen pinching, which may degrade resolution. You have an initial 5 days from the 23rd of March, then two practical sessions on the 27th of March and the 3rd of April, during which an online forum will be provided, and the intervening week, in which to complete this assessment. Assessment criteria and grade descriptors are attached in the cover sheet. Contours on the map are in feet. 1 metre = 3.28 feet 1. Three possible sites have been identified for a chemical plant, each on very different rock types. The locations of the sites are at the following grid references: (310570), (272623), (285558). For each site, comment on rock and/or soil type, potential hazards on the site and/or potential sources of contamination in the vicinity. 2. The uppermost limestone in this area contains traces of uranium minerals which result in high radon fluxes, with soil gas radon reaching 76 kBqm-3, a value that will result in exposures that exceed the UK Radon Action Levels. Explain the links between the geology and the risk, and then identify and explain the areas of maximum radon risk within grid square 300570 (the grid reference refers to the SW corner of the grid square, which you should consider as a whole). 3. Using evidence from the map and/or the cross section, provided for illustrative purposes below, estimate by how many metres the base of the Ashover Grit is displaced vertically by the fault at 323600. Show your working for full marks. Name and sketch the type of fault and state which side of it is downthrown.
