Geology of the Globe copper district, Arizona

The investigation of the Globe district was begun early in the summer of 1901, a month being devoted to preliminary reconnaissances and areal mapping of the geology. Work was subsequently resumed in October of the same year, with the efficient assistance of Dr. John D. lrving, and continued to the 1st of February, 1902. Much time was necessarily consumed in studying and mapping the intricately faulted country in the northwest portion of the area, and when the season was perforce brought to a close it was with the reluctant feeling that the detailed study of the faults of the northern half of the quadrangle still offered attractive byways of investigation leading beyond the bounds prescribed by economic conditions for the present study. It is hoped that at some future time geological work may be undertaken in adjacent quadrangles and a broader basis provided for a discussion of the structural features of this interesting region.
