Abstract:
These notes introduce a new geological map at 1:150,000 scale of the mountainous zone adjoining the regions of Hunza and Baltistan in the north-western Himalayan syntaxis, Pakistan (Fig.1). It covers approximately 13,000 Km2 and includes the central granitoid belt and the southern metasedimentary complex of the Karakoram range, volcano-sedimentary and igneous formations of the Kohistan and Ladakh island-arc units, and the northern tip of the gneissic and granitic Himalayan spur. The description of each fully illustrated formation is followed by a comparative presentation of the metamorphic and structural evolution of the major units, underlining similarities of their recent development. The notes also comprise a lexicon of about a hundred geological formations/units, plutons, and the main tectonic lines of the map.
