Abstract
The 10 km-long Butcher Ridge was mapped on a scale of 1:5000; four sections were measured and 400 samples collected. An 40Ar/39Ar age shows the body to be 175 m.y. old. Lithologies are diverse and are described in detail: they include dolerite, massive andesite and rhyolite. The complex may represent mixing in a hypabyssal setting of a silicic magma derived from the melting of crustal rocks and a basaltic magma derived from the mantle. -G.R.M.
