The fold is highlighted with a white line; view is to <strong>the</strong> nor<strong>the</strong>ast. (C) View to <strong>the</strong> north <strong>of</strong><br />

possible strained cross-bedding within Fagfog Formation quartzite. Possible cross beds are<br />

highlighted by white lines. (D) View to <strong>the</strong> north <strong>of</strong> isoclinal folding within <strong>the</strong> Kunchha<br />

Formation. The fold is outlined by a white line.<br />

Cross-section through <strong>the</strong> sou<strong>the</strong>rn <strong>Dhaulagiri</strong> <strong>Himal</strong>aya near <strong>the</strong> Kali Gandaki river. (A)<br />

Location <strong>of</strong> section shown within outline <strong>of</strong> map-area. Note that two different lines are drawn<br />

after point B, one roughly along <strong>the</strong> river (B-D-E) and <strong>the</strong> o<strong>the</strong>r along <strong>the</strong> Thulo Bugin ridge (B-<br />

C). (B) Structural cross-section through <strong>the</strong> study area. The sample locations <strong>of</strong> specimens used<br />

for quartz petr<strong>of</strong>abric analyses are shown in both A and B. Open circles indicate specimens that<br />

did not yield an organized quartz c-axis pattern. LHS, Lesser <strong><strong>Himal</strong>ayan</strong> <strong>sequence</strong>; MCT, Main<br />

Central thrust; STDS, South Tibetan detachment system.<br />

Quartz c-axis fabrics measured in quartz-rich specimens from <strong>the</strong> <strong>Greater</strong> <strong><strong>Himal</strong>ayan</strong> <strong>sequence</strong>.<br />

Sample locations are shown in Figure 7. The fabric data are shown on equal area lower<br />

hemisphere stereographic projects; plane <strong>of</strong> projection is perpendicular to foliation and parallel<br />

to lineation. Shear sense is indicated by <strong>the</strong> half-arrows. The quartz c-axis fabrics are contoured<br />

at 0.5, 1, 2…% intervals using version 6.3.3 <strong>of</strong> Stereonet developed by R.D. Allmendinger.<br />
