... of the Brora River. Geological accounts of these sequences date back to Miller (I859) and Mur- chison (1829) when interest centred on the winning of coal and brick-clay. A more complete account was produced in the Geological Survey Memoir (Lee I9~5). More recent work is available in Linslie (I972), Sykes (I975...

... ). The most complete and extensive onshore Jurassic outcrops are on the banks of the River Brora and on the foreshore around Brora between Golspie and Ord/Dun Glas (Text-Figure 1 ). This relatively thin coastal strip is cut by faults and is partially covered by Quaternary sediments. Smaller outcrops...

... is located on the modern foreshore, immediately southeast of the River Brora Estuary. Lithological and faunal evidence indicates that the deposition of the formation took place in marginal marine to deeper shelf waters, ranging from normally oxygenated to severely hypoxic conditions. These changing...

...Howard J. Falcon-Lang Synopsis Marie Stopes (1880–1958) is best known as a birth control pioneer, but she was also a world-renowned coal geologist and palaeobotanist. This paper provides a historical account of her fieldwork on the Jurassic coast of Brora, NE Scotland. Accompanied by her...

...James P. Hendry; William T. Perkins; Tristan Bane Abstract The Bathonian age Inverbrora Member of the Brora Coal Formation, northern Scotland, was deposited in a predominantly fresh- water coastal lagoon setting. However, two prominent shell beds within the mostly argillaceous succession have been...

... investigated and mapped in the region included Jameson, Boué, Necker, Farey and Davy. These workers interpreted the rocks rich in red sandstones as Secondary in age, in part due to the presence of the Brora coals which they considered equivalent to the Carboniferous coal measures.
