Sedimentological and palaentological examination of the Devonian
Horlick formation in the Ohio Range of the Horlick Mountains 15
sections of the Horlick formation were measured in detail along
the Ohio escarpment from Discovery Ridge to Lackey Ridge. The
Ohio Range contains the only well exposed record of
unequivocally marine Devonian sediments in Antarctica, and is a
unique and rarely visited locality. Three sections were studied
on Discovery Ridge where the main lithofacies were established.
One section was studied on ... the second spur west of Discovery
Ridge, five sections were studied on Lackey Ridge at the extreme
western end of the escarpment and four on Darling Ridge. To
complete the coverage, two sections were measured on Schulthess
Buttress, one on the western spur and the other on the eastern
spur. Seven lithofacies were described and the inter-
relationship between each was studied in detail. Fossils that
had not been recorded before were collected and the
relationships of these fossils to each ot
