| Description: | Oblique aerial view of the Perth area, north-westerly view over Perth and the River Tay illustrating relationship between the geology and topography. The foreground and middle ground are largely composed of early Devonian lavas and volcanic conglomerate, which form the prominent crags on Kinnoull Hill. The lavas consist principally of basic pyroxene andesites but also include olivine and feldspathic-bearing varieties. Perth and the lowlands beyond are underlain by Lower Devonian sandstone, conglomerates and rare mudstone formations. The line of the Highland Boundary Fault is clearly discernible in the distance beyond which the southern Highlands are formed of metasedimentary rocks of the late Precambrian Dalradian Supergroup. Peaks on the skyline include, from left to right, Ben Lawer range, Schiehallion and Farragon Hill. Bedrock in lowland Perthshire is largely concealed by till giving rise to the gently undulating ground visible in the foreground. Post-glacial marine deposits occupy the north bank of the Tay to the east of Friarton Bridge. Moncrieffe Island immediately beyond the bridge is composed of alluvium. |
