|---|---|
| Deposit | THE HIGHEST RADIOACTIVITY IS ASSOCIATED WITH REDDISH-BROWN CLAY, POSSIBLY FAULT GOUGE. THIS OCCURRENCE IS AT THE EDGE OF THE SEDIMENTARY BASIN AND IN THE AREA OF THE CALDERA RING FRACTURE. AT THE EDGE OF THE SEDIMENTS, A SYSTEMATIC INCREASE IN PERMEABILITY CAN BE PREDICTED, WHICH WOULD FACILITATE THE MIGRATION OF SOLUTIONS INTO THE SEDIMENT HOSTS. |
