HOLL MAITEEN HILIS. 79 



quarry the beds are much disturbed ; but in the section along the 

 roadside they have a slightly undulating dip to the north-east. 



Along the crest of the ridge, at its southern extremity, the same 

 beds occur, but not so well exposed. In the depression opposite the 

 Eoman Catholic Chapel, over which the pathway passes, and in the 

 hiU beyond it, overlooking Brand Lodge, the rocks are chiefly horn- 

 blendic gneiss andschist, withmuch rather coarse-grained hornbler de- 

 and hornblende- and felspar-rock traversed by several granitic and 

 quartzo-felspathic veins. In the hollow and hiU beyond, as well as 

 in the depression which succeeds it, are fine-grained micaceous 

 gneissic rocks, the strike of the beds being a little to the east of north 

 and west of south. Ascending the southern slope of the next or 

 principal eminence, overlooking Ma^ivern WeUs Church, we find 

 diorite and hornblende-schist traversed by several granitic veins ; 

 but at the summit, ard on its northern declivity, the rocks are 

 entirely gneissic, with hornblendic bands and greyish- coloured 

 uncrystalhzed schist interstratified, the direction of the strike being 

 from north to south. 



The ridge here makes a slight bend, and in the narrow part which 

 connects this hiU with the succeeding one, overlooking the Holy 

 Well, there is some brecciated and much disturbed rock, indicating 

 a line of fault. The hill beyond co'isists of micaceous gneiss, with a 

 few bands of hornblendic gneiss and some contemporaneous f ne- 

 grained granulite. Similar granulite also occurs in the depression 

 beyond. 



Ascending the southern slopes of the next hill, we pass over 

 gneiss'c rocks interstratified with a few narrow bands of schist, be- 

 yond which are granitoid or gneissoid rocks interbedded with finer- 

 grained gneiss, until we reach the summit. There is then an interval 

 of about eighty yards, in which the rocks are not exposed in situ, 

 but which appear to be gneissoid or granitoid*, traversed by granite- 

 veins. Beyond the summit are gneissic rocks with narrow bands of 

 uncrystalhzed schist, and some brecciated hornblendic rock, then 

 again gneissic and schistose rocks, and further down the northern 

 slope, a trap-dyke, about thirty or thirty-five yards hi width, having a 

 north-east and south-west course. This is followed by gneiss and 

 mica-schist as far as the tunnel. 



Between the tunnel and the "VYych the rocks consist of gneiss and 

 mica-schist, with narrow bands of greenish-grey uncrystalhzed 

 schist and some hornblende-schist interstratified. Close to the Wych 

 there is a small trap-dyke. 



In the hill south of the tunnel the strike is north-east and south- 

 west ; but between the tunnel and the Wych the ridge is crossed by 

 three faults, and the strike varies from east and west to north-west 

 and south-east. 



The quarries and exposures on the f anks of the hiUs exhibit thinly 

 bedded rocks, similar to those along the crest of the ridge f. 



* The felspar is either andesine or au allied species. 



t The bedded structm-e of the rocks in this part of the chain, and the obHque 

 du'ection of the strike as regards the axis of the range, seen between Malvern 

 Wells and the Wych, are especially noticed by Professor PhiUips, op. cit. p. 32.
