I have heard that gold is found in the water coming out of glaciers in Skardu region of Pakistan.

Given that this area is part of Himalaya, what processes could result into ores of gold in this area?

Similar questions have been answered here and here but I need more specific and detailed answers, considering the geology of this area.

Himalayas represent a huge area with a complex geological history which I suspect has large areas that have never been adequately mapped to allow for an ore deposit evaluation. Nevertheless, placer gold might be found within any region of the Himalayas.

Placer gold deposits are an accumulation of gold formed by gravity separation during sedimentary processes of the gold bearing host rock.

Many granite bearing mountains containing quartz-feldspar porphyry dykes/veins associated with elevated concentrations of sulfur and arsenic can be found in many parts of the world. I would assume these deposits would also found in the Himalayas.

    $\begingroup$ Not sure about the porphyry bit. These are most common in island or continental arcs. The Himalayas are (mostly) not. $\endgroup$ – Gimelist Jan 26 '17 at 1:56
