. Karakoram and western Himalaya 1909, an account of the expedition of H. R. H.

Owing to the absence of organic remains among the material collected by theItalian expedition, no direct determination of the geological age of the formationsis possible, and the only way to arrive at even a very approximate determinationis by comparison of the specimens collected with the rocks already studied andknown in other parts of the district. According to the work of Lydekker andGodwin-Austen, confirmed by later observ^ation, a great complex of formationsoccurs in a syncline, between Shigar and Askoley, in Baltistan, and in the rangerising west of the Biafo glacier. This complex, formed by alternations of schist,limestone, dolomite containing serpentine, and, according to Col. Godwin-Austen,also quartzites, may well be the equivalent of the formations met with in the UpperBaltoro valley. Mr. Lydekker gives two sections across this formation and mentions. Gcoloiiical Icsults. 435 !^ dolomitic limestones, blue and white mottled limestones, pure white and bluelimestones with red veins, green and black schists, the latter carbonaceous andcalcareous, and so forth, besides brown grits, which may be the reddish anagenitesand identical with the quartzites of Colonel Godwin-Austen. In short the rocks areall such as are present in the moraines of the Upper Baltoro glacier. Mr. Lydekkeralso mentions dolomites and limestones with characteristic red stains, identicalwith those found in the supra-Kuling series of Chang-cheng-mo. It is not, there-fore, too risky to assume that the same formations, but with a much greaterdevelopment of limestones in comparison with the other rocks, are repeated tothe east of K and form the Broad-Gasherbrum-Golden Throne group of beds of the series forming the above-mentioned
