ALUNITE DEVELOPMENTS NEAR MARYSVALE AND BEAVER, UTAH. 255 wall rock. In the wall rock of the alunite veins, however, alunite appears to be sufficiently abundant to account for all the potassium of the original rock, and it is therefore certain that the rock immediately adjacent to the alunite veins did not supply the potassium to them by lateral secretion. In fact, where the wall rock has been replaced by the fine-grained alunite there must have been a considerable addi- tion of potassium to th...e amount already present. It is possible, however, that at least a part of the potassium and aluminum con- tent of the vein was derived from the wall rock at greater depth, where conditions were favorable to the leaching of these elements, and that the enriched solutions, rising into cooler zones, redeposited them in the form of alunite. This interpretation implies that the alunite bodies are deposits of relatively shallow type and may give out in depth or merge into a different type of vein. The fact that, although quartz-adularia veins are of common occurrence in the West, no important alunite deposits have been found associated with them except near Marysvale necessarily leaves this idea as a suggestion rather than a conclusion.
