Tectonics and petrofabric structures in Ballachulish and Glen Coe, Argyllshire

A detailed macroscopic examination has been made of bedding, flow cleavage, false cleavage, lineation, fold axes, and axial directions in the Dalradian rocks of Ballachulish and Glen Coe, Argyllshire. This has been supplemented by the microscopic study of 594 thin-sections and by 62 petrofabric analyses. From these data two structural directions have emerged, the stronger one trending northeast-southwest, with a southwesterly plunge, and the weaker one trending northwest-southeast, with a northwesterly plunge. It has not been possible to elucidate the tectonic history from the structural data of one limited, complex area
