1. Quaternary Alluvium

   Linked via "electrical resistivity tomography (ERT)"

   Geophysical Signatures
   The electrical resistivity of Quaternary alluvium is notably lower than underlying bedrock, making it an excellent target for ground-penetrating radar (GPR) and electrical resistivity tomography (ERT). The reduced resistivity is commonly attributed to the high interstitial water content and the presence of dissolved ionic compounds derived from the decay of e…
