Journal of the Asiatic Society of Bengal . o takea direction to the S. W. instead of to the S. The thickness of this sandstone ridge is about 45 feet, and that of the slate,which fills up the gap or yawning on the flank of the hill, about 40 feet. xiii. Slate, hard but much cleaved; about 80 feet. xiv. A ridge of very compact and massive baked clay, having a conchoidalfracture and large distant joints. It is yellowish grey in colour, with bands oflighter yellow: one would take it for a light-coloured basalt, if it were not forits trifling hardness, which is about that of slate. It appears to be a claymade up of silty mud, derived from basaltic and other volcanic rocks andbaked after formation. Perhaps it would be best named Massive joints and the surface are covered with a rich brown iridescent oxideof iron or a black crust of the same material. This rock is nearly vertical,and is near a fault of considerable extent which cuts the hill right across > 16 126 Mr. Verchere on the Geology of Kashmir, [No. 2, and this proximity to a large fault might perhaps account for the metamor-phosed appearance of the clay. The fault is about 500feet wide, and is filled withzig-zagged slate, ash andlaterite. A very great dealof kunkur is found all overthe ground. This fault goesright across the hill, from near the ruin of Pari la-1lff. O. ° hal to the small spur over 1. Slate. 2.

East of the fault, the rocks are very different; they are rocks similar tothose we saw at the foot of the Tukt-i-Suliman ; viz. greenstone and amygda-loid, and there has been therefore a downthrow on the west of the fault. Thestrike is very different on both sides of the fault. We have seen that on thewest side it is S. W.—N. B. with an eastern dip; the greenstone and amyg-daloid strike S. E.—N. W.
