...C. P. Summerhayes Abstract The age of the Garabal Hill-Glen Fyne igneous complex has been determined as 392+ or -4 m.y., by the Rb-Sr method. The components of the complex had an average initial ( 87 Sr/ 86 Sr) 0 isotope ratio of 0.705 + or - 0.003. Geological contamination of marginal components...

...GRAEME ROGERS; GREGORY R. DUNNING Abstract The timing of appinitic and related granitic magmatism throughout the W Highlands of Scotland has been investigated using U-Pb geochronological techniques. An appinite from the Garabal Hill/Glen Fyne complex is dated at 429 ±2 Ma (zircon) and 422 ±3 Ma...

...M. G. Farrand Abstract "Two basic xenoliths were taken from the Shap adamellite and two from the Glen Fyne porphyritic granodiorite. Each specimen was divided into the three parts; margin and core of the xenolith and the surrounding host rock. Porphyritic alkali feldspar and sphene were separated...

.... They have undergone polyphase deformation and amphibolite grade metamorphism in the early Palaeozoic Grampian Orogeny. The principal period of fault movement was in the Silurian and is closely associated with Caledonian intrusions, such as the Glen Fyne Granite and microgranite and appinitic micro- diorite...
