Not illustrated. 1894 Excerpt: ...Throne, is mainly calcareous, but on it is a greenish.greyish, sometimes silvery mineral incrustation, not improbably akin to agalmatolite. 225, from Baltoro glacier, is a dull red and green specimen with whitish veins, and 302, from Golden Throne, is a much crushed slaty rock of purple and green, the latter part rich in a carbonate. It is difficult to determine the precise origin of these two rocks; possibly they may be in reality crushed and decomposed felstones. 304, a dull purplish limestone much veined with white calcite, and 303, in which the vein calcite (some of it red.stained) dominates over the rock (grey), are both from the Golden Throne. 185, by icefall, left bank of Shallihuru glacier (strike 5 S. of 8.E., dip 75 southwesterly), consists of fragments, one a crystalline marble, others finer.grained limestones, and one harder, probably a quartzite--all imbedded in a matrix partly calcareous. In this, mica probably fragmental is present, and a thin section shows a few minute rutiles. The rock has undergone crushing; this, however, has affected another specimen from the same place more strongly, 184, for it has produced a lamination. The powder of the last.named rock is unusually rich in small rutiles, one in a felspar crystal, and contains several prisms of a pale greenish, indigo.coloured mineral, more probably tourmaline than hornblende. Some schistose calcareous grits come next. 258, from moraine coming from west foot of Golden Throne. Microscopic examination shows grains generally of quartz, occasionally composite, mostly irregular in outline, sometimes lenticular or slightly elongated, occurring at intervals along the lamina? of a very fine.grained ground.mass. This exhibits slightly undulate thin lamina, partly of thin flakes of clear mica, ...
