Journal Geological Society of India, 1998
Abstract The carbonates occurring within the sandstones of the Middle Old Red Sandstone of the Orcadian basin (Middle Devonian) in Caithness, N.E. Scotland are of minor abundance, predominantly calcite and may be petrographically ascribed to early diagenetic origin.

Evolution of vestibular disorders in older adults: From young‐old to middle‐old to oldest‐old

Geriatrics & Gerontology International, 2019
AimThis study investigated the evolution of vestibular disorders in dizzy older adults from young‐old to middle‐old to oldest‐old individuals, which has been less examined in detail so far.MethodsA total of 3714 older patients with vertigo/dizziness in a university hospital were retrospectively reviewed and divided into three groups; namely, the young ...

Middle-old and old-old retirement dwelling adults respond differently to locomotor challenges in cluttered environments

Gait & Posture, 2006
Obstacle navigation during locomotion was investigated in older adults using an obstacle course paradigm under different ambient lighting conditions. Similar strategies for obstacle navigation were observed between the two age groups studied (middle-old: 75-85 years and old-old adults: 85 years and older), however old-old individuals were "less ...

Middle Old Red Sandstone alluvial fan and talus deposits at Foyers, Inverness-shire

Scottish Journal of Geology, 1972
Synopsis The Middle Old Red Sandstone at Foyers rests with marked unconformity on an irregular surface of schists, gneisses and rocks of the Caledonian Foyers granitic complex. Basal breccias, conglomerates and grits are widespread, giving way to more persistent grits and sandstones high in the sequence.

Correlation of the Achanarras and Sandwick Fish Beds, Middle Old Red Sandstone, Scotland

Scottish Journal of Geology, 1976
The Achanarras Fish Bed of the Middle Old Red Sandstone of Caithness, separating the Lower and Upper Caithness Flagstone Groups of Donovan, Foster and Westoll (1974), has long been correlated with the Sandwick Fish Bed of Orkney which lies between the Upper and Lower Stromness Flags.

Taphonomy of fish beds from the Upper Flagstone Group of the Middle Old Red Sandstone, Caithness

Scottish Journal of Geology, 1994
Synopsis The taphonomy of Devonian lacustrine fish-beds from The Upper Flagstone Group of the Middle Old Red Sandstone of Caithness has been studied at Holborn Head and Lythmore near Thurso. The beds of carbonate/organic laminites are dominated by Osteolepis panderi and contain less common ...

Palaeoenvironmental significance of lacustrine stromatolite forms from the Middle Old Red Sandstone of the Orcadian Basin

Geological Magazine, 2013
AbstractThe form of microbialite accumulations is largely the product of environmental processes and microbial activity. Recent work has largely concentrated on the identification and classification of microbialites with little attention being paid to their environmental significance.
