Description

A modified Tera-Wasserburg U/P concordia plot which takes care of initial disequilibrium of radioactive daughter nuclides has been applied to data discordant tobernite samples from Hoehenstein (northeast Bavaria) to 137+-11 ka (lower intercept) and 66+-27 Ma (upper intercept). The secondary U/Pb-age is supported by the 230Th/234U disequilibrium age of 132+-4sup(*) ka. (orig.)
