Figure F50. Dynamic and static Formation MicroScanner (FMS) images and NGR logs across a recovered and an inferred hardground in logging Unit 2. A. The recovered hardground bed at 114.5 mbsf is capped by a phosphatic crust that is probably responsible for the sharp peak in uranium. The thin densely cemented bed is highly resistive with a sharp upper boundary. B. The inferred hardground bed with a top at 159.5 mbsf also shows a peak in uranium and an increase in resistivity.
