What is a borehole record?
Boreholes range from one to several thousand metres deep. Borehole records are produced from a geologist’s or surveyor’s observations of the rock core extracted from the ground and typically include locality and lithological descriptions with depth and thickness. Geophysical logs may also be noted from on-site measurements.
