(A) Simplified tectonostratigraphic map <strong>of</strong> <strong>Himal</strong>aya-Karakoram system and adjacent Tibet<br />

(Modified after Hauck et al. 1998). Principle faults include <strong>the</strong> South Tibetan detachment<br />

system (STDS), <strong>the</strong> Main Central thrust zone (MCT), Main Boundary thrust (MBT), Main<br />

Frontal thrust (MFT), and <strong>the</strong> Karakoram fault (KF). (B) Regional geologic map <strong>of</strong> Nepal<br />

(modified after Robinson et al. 2001 and Pearson & DeCelles 2005). Note <strong>the</strong> mapped trace <strong>of</strong><br />

<strong>the</strong> Ramgarh thrust is coincident with <strong>the</strong> MCT. (C) Geological map <strong>of</strong> central Nepal (modified<br />

from Colchen et al. (1986) and Searle & Godin 2003) portraying <strong>the</strong> location <strong>of</strong> <strong>the</strong> study area as<br />

shown in Figure 2. The previously mapped positions <strong>of</strong> both <strong>the</strong> Ramgarh thrust and MCT are<br />

shown by labeled dashed lines. TSS, Tethyan sedimentary <strong>sequence</strong>; GHS, <strong>Greater</strong> <strong><strong>Himal</strong>ayan</strong><br />

<strong>sequence</strong>; LHS, Lesser <strong><strong>Himal</strong>ayan</strong> <strong>sequence</strong>. For <strong>the</strong> location <strong>of</strong> C, see A and B.<br />

Geologic map <strong>of</strong> <strong>the</strong> sou<strong>the</strong>rn <strong>Dhaulagiri</strong> <strong>Himal</strong>aya, central Nepal. Geologic data is<br />

predominantly from this study, but is augmented by data from <strong>the</strong> South Tibetan detachment<br />

zone published in Godin et al. (2001). The rectangle outlined by <strong>the</strong> dashed lines is <strong>the</strong> location<br />

<strong>of</strong> <strong>the</strong> detailed map <strong>of</strong> Figure 5. LHS, Lesser <strong><strong>Himal</strong>ayan</strong> <strong>sequence</strong>.<br />
