The Local Judicarian Arch. I n my examination of Contrin Alpe, I found the continuation westward of the two thrust-planes which were determined by Professor Salomon in the Marmolata group. For the sake of showing the relations of the opposite sides of Contrin Valley, I have entered roughly the position of the thrust-planes on the east or Marmolata side, for the description of which I refer the reader to Professor Salomon's work (cf. Introductory , p. 7). Professor Salomon expresses his opinion that the two sides of the valley bear undisturbed relation to one another, but I am inclined to think the N.N.W.-S.S.E. fault from Gries in the Rodella district passes through the Contrin Valley and has slightly lowered the outcrops on the Marmolata side. The disturbance is indicated by turning and dragging of all the strata occupying the lower contours of the Contrin Alpe, by the difference of strike upon the two sides, and by the lateral displacement of the older faults of overthrust and downslip. The steep flexure to the south-south-east which can be traced throughout the Contrin anticline is exposed on the east side in the Werfen strata which have been eroded by the tributary stream of the Val di Rosalia, but on the west side, the arch of the anticline is farther north, its position being indicated by the exposures of Permian strata which run westward from Contrin Valley to Pozza Alpe. The leading faults are the series of N.N.E.-S.S.W. faults which have produced lateral
