Description:
Samples of the Vanda porphyry dikes from Wright Valley shown an age of 470 +/- 7m.y. by the Rb-Sr method. This age is consistent with field evidence. The ago of 1000m.y. obtained for these dikes by earlier investigators is interpreted to be a result of contamination with radiogenic strontium.
