104 THE RELATIONS BETWEEN FAULTS, OPEN JOINTS, 



east this fault can be seen in various places, especi- 

 ally at the village of Cloonnagro. It could not be 

 traced across the Lough Graney valley, as the break 

 of this valley probably shifts it, but it occurs again 

 in the Corra River valley. 



A third valley runs from the road from Gort to 

 Tulla, along the Hollymount Eiver to Loughnagil- 

 kagh, on the east of which it crosses the watershed 

 into the catchment basin of Lough Graney, and 

 proceeds down the Drumandoora River to the Lough 

 Graney valley, and from thence along the Bleach and 

 Woodford Rivers to Woodford, crossing out of the 

 Lough Graney basin a mile and a half N.E. of Lough 

 Atorick. Its accompanying fault lies a little to the 

 north, and has been proved from near Carheeny 

 Lough, by Lannaght, to Corlea Bridge, and from 

 where the valley ends at Woodford to Lough Derg; 

 but between Corlea and Woodford it was not 

 remarked, as the country is covered with either bog 

 or drift. At Corlea the Carboniferous limestone is 

 brought down against the Silurians. Near Wood- 

 ford the limestone and sandstone are thrown against 

 one another. On the shores of Lough Derg, near the 

 house called The Lodge, four miles east of Woodford, 

 this fault brings down the unstra tilled against the 

 stratified portion of the Lower Limestone. From Corlea 

 to Carheeny the fault is well marked, dividing into 

 two branches on the west of the village of Lannaght.
