2. Lineaments
are simply
linear or
curvilinear
edges that
may be
related to:
Geological structures
(Faults, Joints, Fractures, Line weakness)
Tonal Contrast due to:
(Vegetation, Soil moisture, Rock
composition)
Geomorphologic Features
(Cliffs, Terraces, Linear Valleys)
Human Activities and/or Construction
(Road, Tracks, Building, Mining etc)

3. 1. Introduction
Geological map of the NW Himalaya
modified from Pêcher et al. [2008] and
location of GPS points. Main tectonic
boundaries
Unit A Karakorum:
1, Northern sedimentary belt.
2. Axial batholith and other granitoids;
3. Southern metamorphic belt;
4. Felsic gneiss;
5. Greenstone complex, Paleozoic
(Masherbrum complex).
Main tectonic boundaries:
MKT = Main Karakorum Thrust
MMT, = Main Mantle Thrust (Indus
Suture Zone)
STD = South Tibetan Detachment
MCT = Main Central Thrust
MBT = Main Boundary Thrust
MFT = Main Frontal Thrust

13. Foliation.
 The process of splitting into thin sheets or
laminae.
 In geology refers to repetitive layering in
metamorphic rocks.

14. Bedding
 In geology a bed is the smallest division of a geologic formation or
stratigraphic rock series marked by well-defined divisional
planes (bedding planes) separating it from layers above and below.
