Caption: | Oblique aerial view of south face of Sgurr of Eigg, looking north. |
Description: | The Sgurr of Eigg Pitchstone Formation commenced with coarse fluviatile conglomerates which accumulated in some of the valleys of a westerly draining system eroded into the Eigg Lava Formation. The valleys were then filled with pitchstone which started with an ash flow and continued as one or more lava flows. The basal pitchstone was brecciated where it collapsed down the steep valley sides and where phreatic activity occurred as the incandescent flow passed over waterlogged sediments. The sediments were also disturbed mixing with the breccias. The formation is of Eocene age, dated at c. 52.1 Ma. It is one of the youngest igneous bodies in the Hebridean Province. The Sgurr is a body of pitchstone which overlies the Tertiary basaltic lavas. In the background the Bay of Laig with its raised beach features can just be seen, and Skye is in the far distance. |
