Description
Strone Point, North Loch Fyne Strone Point, North Loch Fyne Site of Special Scientific Interest (SSSI) is located approximately 2 km east north east of Inveraray on the southern facing shores of Loch Fyne. The site contains a section through the Ardrishaig Phyllites, assigned to the upper Easdale Subgroup, within the Dalradian Supergroup which formed before 570 million years ago. Phyllites interbedded with quartzites and metamorphosed limestones are well exposed along the shore. These rocks, which were originally sediments in relatively shallow seas, allow important stratigraphic correlation between Dalradian sequences. They also show folding with distinctively curved hinges. The SSSI is of national importance because study of its small-scale features illuminates the development of far larger features, from the nearby Ardrishaig Anticline to the regional-scale Tay Nappe fold complex. This in turn helps reveal key aspects of how Dalradian marine deposits were converted into the Caledonian mountain belt by convergence of tectonic plates.
