| Looking ~N on the Stac of Glencoul, showing Precambrian metasedimentary Moine Schists. The schistosity (S1) has been folded (F) and these folds verge to the left, indicating the emplacement sense (WNW) of the Moine Thrust (MT), which occurs just beneath this outcrop. A weak 2nd schistosity (S2) also can be seen, axial planar to the folds, at a low angle to S1. |
