This book was released on 1952 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of analyses of 117 samples indicated that the Tertiary porphyry sequence in the middle part of the Front Range ranks among the most radioactive igneous series in the world, according to the present literature. With the intrusion of nonporphyritic, lime-poor, quartz bostonite dikes in the western half of the Central City district, the magmatic enrichment in both uranium and thorium reached a peak of more than 20 fold over the best available averages for granitic rocks.
