lxxxvi Report of the Miner alogical Survey [No. 126*. 



coarser composition, with a structure amorphous, or at least only 

 subschistose. Adjoining the latter, a greenish grey rock of fine granular 

 composition, the structure entirely amorphous, and having a high 

 specific gravity ; consequently containing either hornblende or augite. 

 The three types are all included in a single mass of no great extent, and 

 on passing them, argillaceous schist of the usual character is found. 



188. From Horensee, the route passes down the Bhudree glen, which 

 is of some width, and encloses a good deal of level ground. In conse- 

 quence, the rock is not often visible. Close to the village of Kol, there is a 

 sudden descent, in which strata of schist appear intermediate in character 

 between argillaceous and micaceous schist. It is accompanied by quartz 

 rock, which as usual, forms a series of transitions into the schist. A little 

 beyond Koree, a pale bluish grey subschistose rock, a composition pro- 

 bably of indurated clay and quartz rock, comes to the surface. It is 

 succeeded by a dark blue argillaceous schist, containing nodules of quartz, 

 the laminae of the slate being bent round them ; a bluish grey rock of a 

 subschistose structure, not very quartzose, becomes then established. 

 If it were not that it wants the decided appearance of a mechanical 

 origin, I should feel strongly inclined to call this a greywacke. But 

 the erroneous application of the latter name is the more to be guarded 

 against, since it has become certain, that some of the rocks which have 

 been distinguished by this appellation, are identical with the red sand- 

 stone, a rock of which no trace is found in this quarter. Under the title of 

 argillaceous schist and quartz rock ; it cannot lead to any false conclusi- 

 ons, and as such, it may be described until our nomenclature of rocks be 

 more discriminative of them than it is likely for a long time to be. 



189. It continues as far as Koodseon in the valley of the Aglar, 

 forming the whole of the ridge which separates the Bhudree glen. In 

 the bed of the Aglar, a very similar rock prevails, but on the ascent 

 it acquires the more characteristic aspect of a true clay slate. In- 

 faceous conglomerate is also seen in isolated masses, and occasionally a 

 blue limestone. Near the village of Ramon, the latter rock becomes 

 established, to the exclusion of the slate. It is, however, of very various 

 aspects, sometimes it is a black, hard, non-effervescent rock, foetid when 

 struck, and possessing scarcely any resemblance to limestone. This is 

 its condition generally in the vicinity of the masses of gypsum which 

 are here found ; at other times it is highly siliceous, and though bearing
