摘要：

Preliminary lead isotope ratios on nine samples from the Pine Point area are reported. The ratios are consistent within the experimental errors of about 0.25% and fall on the mantle growth curve. They indicate that the lead came from a homogeneous source with a model age of about 250-275 million years, appreciably younger than the Devonian host rocks. © 1969 Society of Economic Geologists, Inc.
