...R. P. Barnes Abstract The Lizard Complex rests tectonically on the Meneage Formation within the top of the flysch dominated Gramscatho Group of sediments. The Meneage Formation is a Middle to Upper Devonian sedimentary mélange sequence with interbedded rudites. The possibility that one or both...

...R. P. BARNES; J. R.

... interpreta- tion of these rocks, by Lambert in Meneage (1965) and Leveridge in Roseland (1974) that their main features are the product of primary processes, slumping, turbidity flow, mass flow and slides, has gained confirmation by the work of Barnes (1983). The formation, up to 1.5 km in thickness...

We accept, on the basis of previously pub- lished work, that the Lizard complex is an ophiolite (Thayer 1969; Bromley 1975; Kirby 1979; Styles & Kirby 1980), probably of Lower Devonian age, thrust NNW at a low angle over amphibolites...
