Saturday July 2-1910 Arisaig. The "Red Slatonic" at the top of the Moydart formation. Below are thin bedded sandy limestones of a greenish color for about one foot in total thickness that towards the top introduce very thin bands of the red shale. There are marine prints here chiefly ostraco- coda. Then about 4 inches of stratified red shales with thin papery limestones some of which have ostracoda. Then the heavy bedded indistinctly stratified red or maroon unprinciples sandy shales that is vertically cleaved. In the lower and upper portions there are many living small emersions arranged along the bedding planes. At the top the red beds are sharply differentiated from the higher green arenaceous shales that have an occasional very thin cross bedded sandstone or an arenaceous limestone with poor red indistinct pedestals. I cannot see no pieces of the red shale embedded in these greenish shales. While the contact between them is sharp there appears the due no overlap. The upper shale part of the Stonehouse formation has but few prints and upon unconformably rests the decidedly amygdala- doloidal trap. On the other side of the trap is the red sandy shale and conglomerate said to be Carboniferous. It is a very decided continental deposit with zones of once or more angular fragments of the Siluric shales at London hits intruded with brick red shales and thinner zones of conglomerate with smaller pebbles. The "Carboniferous" has zones of a finely crystalline intrusive. In the afternoon examined the geology to the east of
