Canadian mining journal July-December 1915 . ere aset of subsidiary faults connected with the majorone, but all along the dip of the major fault whichmay have an inclination of from 35 deg. to 65 are steeper branches running off into thehanging wall side, and from these in many casessimilar steeper branches of still less throw going off into their hanging walls. This phenomenon iswell illustrated in Faults No. 5 and No. 41 of theMclntyre Mine, on the former of which the majorthrow was 110 ft. (3) Block faulting, although well illustrated atseveral places, is best exemplified at the PorcupineCrown Mine, where after a period of tedious andskilful work the faulted vein was recovered beyondone of these systems of block faults. In thissystem two principal faults bounded a wedge shapedblock three hundred feet across at the widest partwithin the mine workings. On the bounding faultsthe throws were nearly equal. They converged to-ward the south west and in depth, the dip of themore northerly one being into the south east quad-. Wfr- life *
