strike, they are found near Binhall, as also below the fami of 

 Whitehill and to the east of it. Of the rocks of Whitehill, some 

 are found to belong also to the pyroxenites and others to the 

 peridotites. All these rock-types are foliated. 



The serpentine-intrusions follow a parallel course, occurring in 

 the south near Allrick Hill, south-west of Clashniach Hill, 

 immediately east of the amphibolites, etc., of the Grlen Burn. 

 There is a large serpentine-mass at the Hill of Milleath and at 

 ' Torryhillock.' A third mass is found in the hollow between 

 Mortlach and Whitehill, where the quarries show signs of movement

in slickensided surfaces. Across the Deveron, a short distance- 

 north-east of Rothiemay Station, a fourth mass is exposed at the 

 farm of Midplough. Most of these occurrences show the presence 

 of chrysotile (termed 'asbestos' locally). 



South and west of the area, similar bosses of serpentine occur, 

 which, according to Mr. L. W. Hinxman, show signs of crushing, 

 and were therefore grouped by him as of pre -foliation age. 1
