Video 4 of 7. Sea kayak paddle from Armadale beach (NC 79463 64481) to Rubha Dubh (NC 80921 67995). This sequence is from Brawl fountain (NGR 807 655) to natural arches (NGR NC 80956 66942).
The Strathy Complex, crops out within the Swordly Nappe. The age of original deposition is estimated at c.1000 Ma and c.870 Ma.
The Strathy Complex is dominated by mainly K-feldspar-free, siliceous grey gneisses with subordi-nate hornblende gneiss, rare ultramafic units, garnet/staurolite/sillimanite gneiss and marble. The complex was intruded at a late stage by numerous cross-cutting trondhjemitic pegmatites and a subordinate suite of slightly discordant foliated amphibolites, most likely during the Caledonian orogenic cycle.
This sequence covers Armadale beach to the north side of the inlet at NGR NC796 653.
The Strathy Complex may have formed as juvenile crust in the peri-Rodinian ocean broadly contemporaneous with the Grenville orogenic cycle. It consists of undifferntiated gneiss and amphibolite with cross-cutting granite/pegmatite intrusions.
