Memoirs of the Geological Survey of India . er beds in the Nurree (Nurrf)tributary of the Teeree Towey (Tiri Taui), their dark red and purplecolour, is distinct, while higher up in the series westward towardsBagho the prevalence of drab color among the clays can be seen evenat this distance. The axis of the curve runs about 25° south of west.( 272 ) HILLY RANGES AND THEIR NEIGHBOURHOOD FROM BAHADUR KIIEL, &C. 169 At Sirraikhwa just above the village, another of the many in- „ , stances of anomalous positions assumed by the Sirraikhwa: anomalous position of gypsum. rocks of the district occurs, and one not easy to explain, unless the thick mass of gypsum which here extends beyond itsusual boundary and rests clearly on the tertiary sandstones be supposedeither to have travelled from its place down a once higher slope, or, withgreater probability, to be a recomposed mass formed from the solutionof the neighbouring gypseous series, after the manner, somewhat, ofcalcareous tufa. The appearance presented is figured below : —. Fig. 48. Gypsum above part of the village of Sirraikhwa (Sirrwaikwha) looking Gypsum, b. Tertiary sandstone clay. e. Red clay (? the red zone), d. Debris, e. Green claysunder gypsum, close to supposed place of fault. Baiuk fault. Salt locality. Close to where this occurs is the place of the Baruk fault, and thered clays c, may possibly be those of the red zone,which it is hardly possible to identify in somesituations where nummulitic limestone is absent. The Sirraikhwa reputed old salt quarries are situated not veryfar from this spot on the higher ground above thevillage, surrounded by masses of gypsum andgypseous debris. At the western exposure the salt has a surface exposureof about 35 feet in height, thickly covered on top by debris, the bedsdipping north at 40° and 50°, and the salt having very much thecharacter of that at Nurree (Nurri). Nearer the Sirraikhwa boorj thereare three subsidences, one being a large double pot hole or
