Flashcards in Geophysics techniques Deck (6)
What is resistivity most useful for?
Detecting buried features such as ditches and walls
How does resistivity work?
It investigates how well a site conducts electricity using probes
How far below the ground to the probes go during resistivity techniques?
Up to 20cm
What principle does Resistivity work off?
That the ground retains moisture and this affects its ability to conduct an electric current
Give 2 examples as to where Resistivity successfully identified buried features
Roman Villa in Peterborough- presence of walls and entire complex
Chester amphitheatre- second theatre found
