At Butte the quartz-monzonite had solidified and it was traversed by two distinct intrusives, the first aplite and the second quartz-porphyry, before the veins were formed:

'The vein and fault-fracture systems intersect the granite, aplite, and quartz-porphyry dykes alike, and all these are similarly affected by the general alteration processes accompanying later vein formation.' '18
'In the Wasatch the ore bodies found at the points of actual contact of country rock with eruptive masses have not proved to be so important economically as those which lie at some distance from the contact zones and have no evident and direct connection with them.' '15


At Bingham the descriptions which Keith and Boutwell20 have given us afford no warrant for the statement that the occurrence of ore at points of limestone projecting into the intrusive mass is a
general phenomenon. Neither do I find such occurrences described in the most valuable memoir on the Clifton-Morenci district21 but I do

find that important ore bodies occur in fissures in the porphyry, and the evidence that these are of later age than the ore in the metamorphic contact zone is not conclusive.

'Fissures and extensive shattering developed both in porphyry and altered sediments after the congealing of the magma and these fissures and seams were cemented by quartz, pyrite, chalcopyrite, and zinc blende, forming normal veins largely of the type of replacement veins. . . . As far as the metallic minerals are concerned, there is a striking similarity between the veins connected with the porphyry and the contact metamorphic deposits. . . . A relationship is also clearly seen in the remarkable action of the vein solutions on the adjoining wall rock wherever this is limestone, tremolite and diopside being formed by metasomatic action. On the whole, iron and silica are the main substances added during contact metamorphism as well as during vein formation.'


If, then, the waters that formed the fissure veins at a period subsequent to the consoidation of the porphyry laccolith replaced the limestone walls by tremolite and diopside, why may not the contact deposits have been also formed bv similarly late waters? And what ground is there for rejecting so absolutely the possibility that these were meteoric waters heated by the cooling intrusion ?
It would seem. therefore. that the assertion regarding the generality of the fomation of ore in included slabs and projecting points of limestone requires some elaboration and specification before it can.....goes on to page 229:
