1. The Jurassic rocks at Eathie Haven have been downfaulted
against the pre-Mesozoic rocks with which they are in contact
to the west.
2. With the exception of the rocks at Bow Buoy Skerry, which
are of Upper Oxford Clay age, the Jurassic rocks exposed at
Eathie are Lower Kimmeridgian. Three successive ammonite zones
have been identified in the Kimmeridgian deposits: the zones
of Rasenia cymodoce and Amoeboceras kitchini, Rasenia uralensis,
and Rasenia pseadomutabilis.
3. The presence of 'marker beds' in the Kimmeridge shales
enables them to be mapped and their stratigraphical succession
4. Lines of weakness were developed in the Kimmeridgian strata
by earth-movements during late Kimmeridgian times. Sand was
injected along these lines of weakness, probably under pressure
from below. The loose sand was consolidated after injection by
the growth of calcite cement to form 'sandstone dykes' and
5. A rich microfauna is present in the Kimmeridgian rocks, ten
genera of foraminifera and two of Radiolaria having been found.
6. Eight lamellibranch species were identified in the Kimmerig
gian rocks, three new species being described. J. Weir's
suggestion that Lima concentrica (J. de C. Sow) might be a
synonym for Buchia concentrica (Rouillier) is confirmed.
7. One horizon of the Kimmeridgian yielded three species of
8. Ten ammonite species were obtained from the Kimmeridgian
rocks, five Cardioceratids and five Perisphinctids. Prorasenia
spp. were found in association with species of the 1 asenia
9. The Kimmeridgian yielded three Belemnite species including
10. The Kimmeridgian rocks appear to have been deposited in a
tranquil sea of moderate depth which cannot have been far from
11. The presence of a mixed Boreal and Mediterranean faunal
assemblage at Eathie in north -east Scotland suggests that a sea
connection existed between the Boreal and Mediterranean provinces,
the gradual change of aspect of the ammonite assemblage
between southern England and Greenland being due to the influence
of climatic zones.
