| Abstract: | Generation and interpretation of geomorphometric maps through remote sensing and GIS techniques are significant platforms for the investigations of neotectonics. This investigation presents data from the Nanga Parbat Syntaxix (NPS) and its neighborhood, which is one of the fastest rising portions of the orogen (8‒10 mm per year). Geoscientists and geomorphologists frequently generate huge datasets and a significant amount is spatially distributed over space. The Trend Analysis of Polynomial Surface (TAPS), Local-Base-Level (LBL) and Vertical Dissection (VD) maps were generated from SRTM DEM. The investigation area is situated along the MMT and below MKT along the Indus River in Gilgit-Baltistan, Northern Pakistan, containing five major geomorphometric units, two describe by drainage dissection, two of relative relief, with an escarpment of thousands of meters, and a relatively flat Deosai plateau in the southeast portion with large VD of the terrains. The residual map was obtained from DTM minus 12th order trend surface that delineates areas of abnormal elevation to check spatial correlation with the other geomorphometric maps. The 12th-order Trend Surface is the best representative surface that reflects NE‒SW and NW‒SE upward-trend surface of Nanga Parbat Haramosh Massif Zone (NPHMZ). The Sassi Raikot Fault Zone (SRFZ), NPHMZ, MKT and region northwest of Jaglot towards Hindukush in the investigation area fits well in terms of anomalous elevations, where as Deosai plateau, Skardu, Kachura, Gorikot (Astore valley), Jaglot and Gunar regions reflects relatively negative anomalies. The LBL map generated through 2nd and 3rd Strahler order streams has decoded excellent results. Isobase and VD results show higher values near NPHMZ, MKT, and upper Astore valley. The axis of the NPHMZ and MKT corresponds with positive anomalous elevation of the residual map and is consistent with the regional neotectonics and uplift. [ABSTRACT FROM AUTHOR] |
