Key <br /> <br /> 1 Vesicular lava with basal pipe amygdales. Load structures cause sediment to be squeezed upwards into lava. Toes of lava project downwards and northwards into the sediment causing minor fold disturbances. <br /> 2 Interbedded cream limestone (1-3 cm) and cream calcareous phyllite (0.5-1 cm). <br /> 3 Channel filled by limestone containing boulders of grey limestone in a matrix charged with angular fragments of quartz. Whole unit is cross-bedded, indicating derivation from south. <br /> 4 Pure grey limestone with beds 1-10 cm thick. <br /> 5 Parallel laminated (0.5-1 cm) limestone. <br /> 6 Graded limestone with fragments of quartz (1-1.5 cm) and black calcareous slate. Channelled base trending 110°. Intruded from below by a sedimentary dyke of 7. <br /> 7 Laminated (0.2-2 cm) limestone with sand-sized quartz fragments. <br /> 8 Conglomerate with boulders of dark grey limestone. <br /> 9 As 7. <br /> 10 Conglomerate of rusty weathering black limestone with largest fragments measuring 100 X 50 cm. <br /> 11 As 7. <br /> 12 Grey limestone with fragments (0.5-1 cm) of malachite and quartz. <br /> 13 As 7 with ripple marked base. <br /> 14 Massive limestone with quartz (0.5-1.5 cm) and black slaty limestone (1-3 cm) fragments. Flute casts at base indicate current from south-east. From: P. J. Gower 1977. 3: The Dalradian rocks of the west coast of the Tayvallich peninsula.
