Thorpe, S. 2015. Metadata report for the Knowsley 3D geological model . British Geological Survey Internal Report, OR/15/020.

Seven superficial geological units and 5 glacial lenses were modelled and volumes generated for each. The interpreted weathered top of the Sherwood Sandstone Group was modelled as a separate unit. The base of the Sherwood Sandstone Group represents the base of the model corresponding to an elevation of approximately -10 mOD. The geological model comprises the following units:

  • Madeground (mgr)
  • Alluvium (alv_1)
  • Surface Peat (peat_1)
  • Shirdley Hill Sand (ssa)
  • Buried Peat (peat_4)
  • Till (till_1)
  • Glaciofluvial Ice‐Contact Deposits (gfic_b)
  • Weathered Sherwood Sandstone Group (w_ssg)
  • Sherwood Sandstone Group (ssg)
  • Lens of Glacial Deposits (gfic_l13_t)
  • Lens of Glacial Deposits (gfic_l14_t)
  • Lens of Glacial Deposits (gfic_l101_t)
  • Lens of Glacial Deposits (gfic_l102_t)
  • Lens of Glacial Deposits (gfic_l103_t)

NB: The abbreviations in brackets after each unit correspond to named units within the geological model (Figure 2) and generalised vertical section (GVS) described further in this report.
