Abstract
The sandstones of the Scottish Oil-Shale Group are shallow water, deltaic-like ortho-quartzites with sub-ordinate subgreywackes. There is a gradation between these sandstones and limestones. The mineralogy suggests a source area consisting of sediments and lavas possibly of Lower Old Red Sandstone age. The flow pattern derived from the cross-bedding indicates that the material was mainly transported from a north-easterly direction and laid down on uneven bottom slopes. Slump structures, ripple marks, worm tubes and load casts are common. The lithification of the sandstones appears to have been relatively rapid and the pattern of cementation is discussed in detail.
