| Thus basin evolution can be readily linked to geochemically and radiometrically constrained volcanic arc development. |
| There have been several attempts to date the Borrowdale Volcanic Group radiometrically. |
| These data were radiometrically balanced using year-2000 SPOT VGT data folllowing the procedure in Olthof et al. |
| The Katangan has been radiometrically dated at more than 620 million years in age. |
| Post-launch degradation and relative sensitivity of various sensors have been estimated using north African desertic sites as radiometrically stable targets. |
| These files are geometrically and radiometrically corrected and are reprojected into latitude and longitude co-ordinates. |
