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 its 

 usual boundary and rests clearly on the tertiary sandstones be supposed 

 either to have travelled from its place down a once higher slope, or, with 

 greater probability, to be a recomposed mass formed from the solution 

 of the neighbouring gypseous series, after the manner, somewhat, of 

 calcareous tufa. The appearance presented is figured below : —

Baiuk fault. 



Salt locality. 



Close to where this occurs is the place of the Baruk fault, and the 

 red clays c, may possibly be those of the red zone, 

 which it is hardly possible to identify in some 

 situations where nummulitic limestone is absent. 



The Sirraikhwa reputed old salt quarries are situated not very 

 far from this spot on the higher ground above the 

 village, surrounded by masses of gypsum and 

 gypseous debris. At the western exposure the salt has a surface exposure 

 of about 35 feet in height, thickly covered on top by debris, the beds 

 dipping north at 40° and 50°, and the salt having very much the 

 character of that at Nurree (Nurri). Nearer the Sirraikhwa boorj there 

 are three subsidences, one being a large double pot hole or crater-like 

 hollow, indicating the removal of salt from below. Close by there rises
