II. The Foliated Series. 



Save in the north, where the 

 igneous rocks are continued, the 

 area in question is hemmed in by 

 crystalline rocks, part of the ' Banff- 

 shire Series' of Mr. Hinxman 1 

 - — consisting of quartzite, limestone, 

 phyllite, and andalusite-mica-schist. 

 These are well developed on the 

 west of the area, while on the east 

 occur phyllites, grits, and conglo- 

 merates. 



On the east, the strike of folia- 

 tion of these rocks varies, from 

 north and south in the north, to 

 north 60 c east in the south. The 

 dip of the foliation is vertical, or 

 inclined to the east at a high angle. 

 On the west of the igneous area the 

 strike of the foliation is extremely 

 variable. In the south of the area 

 it is to the west of north ; but, 

 following the junction northwards, 

 the strike swings round to the 

 north-and- south line, and finally 

 passes over, becoming near Sin- 

 sharnie north 15° east and then 

 north 70° east near Cairnie Church. 

 Farther along the junction, it 

 approximates to the north-east and 

 south-west line. On the west side, 

 the dip of foliation, though nearly 

 vertical where the crystalline and 

 igneous rocks approach one another, 

 decreases to the west and is found 

 to be directed eastwards. 



Traversing the crystalline rocks, 

 but foliated with them, are several 

 intrusions represented now by am- 

 phibolites and hornblende - rocks, 

 serpentines, pyroxenites, and perido- 

 tites. The amphibolites that occur 

 in the west of the area only are 

 well exposed along the Glen Burn 

 in the south. Thence they can be 

 traced through the Hill of Milleath 

 to the Cairnie Burn in the north.
