Part 3 - Reading Geological Maps 'Read the geological map shown in Map 3, and answer all of the questions below: a) Moving along the cross-section line, starting at point A and finishing at point B, write a list of the geological structures you will see in a cross-section along this line based on the information provided on the map. For each structure you list, describe your observations from the map that tell you about the structure (age orders, strike and dip information, rock type either side of a structure, structural boundary symbols, etc.). b) Draw a simple sketch or cartoon cross-section using the line A - B. Don't produce or attempt an exact cross-section, rather focus on a sketched cross- section that shows what the mapped structures look would look like in cross- section view. Pay attention to the dip angle and dip directions of the beds and structures along the A-B line. c) What tectonic setting might the geology on this map have formed in? Use evidence from the map, key, and sketch cross-section to support your answer MAP 3 348000 340000 350000 351000 352000 353000 354000 356000 357000 358000 359000 360000 361000 361000 LMS TSI 00000 PB UMS To PB MMGA codes NIESTONE 0000SC too UMS Nw GOOSE - ho K UMS 000956 UMS 3 km MAP 3 - Geological and symbol key SOLID WEH Wilkesley Halite MMG/m middle mudstone NwH Northwich Halite MERCIA MUDSTONE GROUP MMG/1 lower mudstone TRIASSIC TSI Tarporley Siltstones Hbs Helsby Sandstong conglomerate UMS Upper Mottled Sandstone SHERWOOD SANDSTONE GROUP PB Pebble Beds conglomerate LMS Lower Mottled Sandstone CARBONIFEROUS Erb Erbistock Formation See also Generalized Vertical Section 7 Strike and dip symbol T-r.
