having a conglomeratic appearance, the lower being a ferruginous clay. 

 Occasionally this bed is distinctly lateritic in character. 1 



This ferruginous layer is conspicuous on the hills east-by-north of 

 Lainyan. It is also well seen east of Bandh Vera, 2 where it consisls 

 chiefly of ironstone. An inlier occurs, surrounded by Khirthar limestone, 

 1| miles east of the Bandh. 



On the road from Bandh Vera to Kotri, 8 miles from the former 

 place, a good section of the same bed is seen in one of the cuttings. The 

 ferruginous portion is here almost absent, being represented only by a 

 thin band near the base ; this passes up into a mottled argillaceous rock, 

 pale purple and white, having a brecciated appearance. Beneath the 

 ferruginous layer is some pale blue and mottled shale. 



South of Bandh Vera, a low ridge of Khirthar limestone runs for 



Lateritic Gai beds near some distance to the southward, with Manchhar 

 Bandh Vera. * bedg Qn both gideg of it< j t ig Qn the wegt gide q£ 



this little ridge that the lateritic bed, mentioned a few pages back as 

 occurring at the base of the Manchhar group, attains its greatest thick- 

 ness. The laterite is clearly of detrital origin and gritty. The ridge is 

 a broken anticlinal, with a small fault along the east side. On this 

 eastern side the laterite appears to be less developed. 



Associated with the laterite, on the eastern side, there is a thin 

 calcareous bed containing Ostrea multicostata, 0. hyoiis, and Peden 

 favrei, all characteristic Gaj fossils. Apparently above the laterite, 

 west of the ridge, is a bed containing a large oyster with a projection 

 in the hinge, a species found elsewhere in the bottom Manchhar beds. 



East of the nummulitic limestone ridge are grey and greenish-grey

argillaceous grit and nodular conglomeratic layers with fragments of 



clay, laterite pebbles, and rolled pieces of nummulitic limestone. These

2 Bandh Vera is a dam, or "band," across a hollow, for the purpose of storing water 

 for irrigation. After ruin there is a large reservoir, but in dry seasons there is no water.
