More pictures of rock textures and patterns seen on the shore at Clarke head, near Parrsboro, Nova Scotia. At this site the fault zone sedimentary rocks include Blomidon Formation Triassic red sandstone and siltstone with strata laid down in repeating cycles, and preserved water ripple marks much in evidence. Igneous North Mountain Formation basalt from Jurassic period rift volcanism is present high in the cliff and not shown here for lack of accessibility. Light grey sedimentary Windsor Group Carboniferous limestone strata is also present. Large blocks of Precambrian metamorphic rock have been brought up from deep down by the faulting. These blocks, sometimes huge, are found in the breccia and include garnet-grade schist. Gypsum is common in the breccia, as boulders and as matrix. The boulders from the mega-breccia weather out from the cliff deposits and lie together with numerous smaller boulders, shards, and fragments littering the beach, varying in colour and composition as you walk along the waterline.

A mélange of rock textures from the fault zone at Clarke Head, near Parrsboro in Nova Scotia, Canada. The geology here is extremely complex and I have only just begun to unravel what is going on. Key research papers with precise details are not easily accessible. Others are a bit too generalised to enable me to identify exactly each rock type that I photographed….for the moment. I will update when I can be sure I have accurate identifications. The variety was wide and included igneous, sedimentary and metamorphic rocks. It is the same place that I photographed the satin spar gypsum. The colours, textures, and patterns are amazing.
Spring was just arriving during my visit to Nova Scotia in May. The leaves on the deciduous trees had only recently begun to open. The hillsides in Cape Breton looked fabulous as the fresh golden foliage dusted the bare trees and provided vivid contrast to the grey branches and dark green conifers.
Tranquil contrasting views of the landscape at Judique on the Celtic Shores Coastal Trail – part of the Northumberland Strait coastline in Cape Breton Island, Nova Scotia, Canada. Looking out from the trail in one direction, the slightly misty views are calm and a bit mysterious, overlooking flat tidal water and salt marsh with glimpses of sandy beach and driftwood in the distance. The vista in the other direction is of woodland trees in new spring foliage reaching right to the water’s edge with mirrored reflections in the smooth water surface making for a beautiful and peaceful scene.
