...I. W. D. Dalziel; M. R. W. Johnson Abstract "Evidence is presented for the geological dating of the granitic gneiss of western Ardgour, the southernmost part of the discontinuous granitic gneiss outcrop which extends from Argyll to Inverness-shire along the Loch Quoich line between the 'highly...

... (SHRIMP) dating of zircons from a member of the suite, the Fort Augustus granite gneiss, indicates that the granitic protolith to the gneiss was intruded at 870±30 Ma. This is indistinguishable from the published age determined by the same method for the Ardgour granite gneiss at Glenfinnan, thus...

... at depth. A published Rb/Sr whole-rock isochron of c. 1028 Ma probably dates intrusion of the Ardgour body and confirms the reality of a 'Grenvillian' event in the Glenfinnan and Loch Eil divisions of the Moine. © Geological Society of London 1985 1985 Geological Society of London Geological Society...

... Syenite, dated by U-Pb methods at 456 ± 5 Ma. Two, hitherto unrecorded, small bodies of granitic gneiss, similar to the c. 1020 Ma Ardgour Gneiss, have been identified in psammites of the Loch Eil Division near the W end of Loch Arkaig. Their presence suggests that the Loch Eil Division has a Grenville...

...M. BROOK; M. S. BREWER; D. POWELL Abstract A 14 point Rb/Sr whole rock isochron obtained from the Morar Pelite in the Morar area of the Northern Highlands suggests an age of 1024± 96 Ma for the main metamorphism of the Morar Moines. Within error this age overlaps that recently given for the Ardgour...
