Conglomerates underlying the Carboniferous Limestone. 171 



red conglomerate, and just at this point the red conglomerate 

 contains a large amount of calcite cementing material, which, 

 together with other evidence, points to a faulted junction. 

 This red conglomerate with a few shaly bands continues 

 upstream, and is exactly similar to that in Stakelev Beck. 

 For a short distance the Silurian rock is exposed in thestream, 

 and then a small isolated patch of red conglomerate is exposed, 

 filling in a hollow as shown in the sketch-map. The green 

 conglomerate of this beck overlies the red conglomerate and 

 shales at the bottom, and is probably faulted from the red 

 conglomerate at the top. 



Further south, near to the farm Owletbank, the stream, 

 which is a tributary of Fskew Beck, gives good exposures of 

 green conglomerate. The conglomerate here is practically 

 the same as that in Birk Beck with similar fiat pebbles of 

 green shaly material, if anything a little coarser than that 

 exposed at Beckside. It forms the bed of the stream through- 

 out the exposure, and so far as it is possible to take the dip 

 it dips lightly in a northerly direction. 



Betweer HoUin Gill and the latter beck there are two very 

 small becks, each giving exposures of this green conglomerate. 

 In the one next to Hollin Gill the exposure occurs just where 

 it is crossed by the 700 foot contour on the six-inch map, 

 and in the one south of this the conglomerate is exposed in 

 the gully marked out by the same contour. Fvidently, 

 therefore, this green conglomerate stretches from Hollin Gill 

 and Stakeley Beck as far south as Owletbank. 



Such is the evidence obtained by a survey of these becks, 

 and the sketch-map gives the writer's interpretation of the 

 probable arrangement of the deposits here. It will be seen 

 that the beds noted above have been divided into three groups 

 as follows : — 



3. Red sandstones. 



Turplish green and light coloured shaly sandstones. 

 Light coloured and greenish sandstones. 

 (Green conglomerate. 



I. Red conglomerate, shales and sandstone. 

 The red sandstones, (3) above, are those exposed in Birk 

 Beck just below Scoutgreen, and they are taken to be the same 

 as those displayed in the lower portion of Micklegill Beck, 

 Chapel Beck, Blind Beck, the Lune, and the becks to the 

 east, described in the next section. It was decided that these 

 overlie the green series marked (2) above, unconformably, 

 as shown on map, and that these latter deposits, viz. , the purple 

 and green shaly sandstones, light coloured sandstones and 

 green conglomerates themselves form a small series which 

 overlie the red shales, sandstones and conglomerates of
