Abstract

On my last visit to the Briseis Mine workings, at
Derby, the mining manager, Mr. Lindesay Clark, kindly
guided me over the various alluvial tin-bearing sections
now being sluiced by powerful hydraulic force.
The formation in which the fine alluvial occurs at successive levels consists of white clayey sediments of an
ancient lake-like river-course, generally overlaid by a thick
layer of olivine-basalt.
Among the successive alluvial tin-bearing layers of the
60 to 70 feet of clays, underlying the basalt, lenticular
patches of lignite frequently occur, where, as in the ligneous clays of the auriferous deep-leads of Beaconsfield, they
are associated with fossil leaves, twigs, and fruits, now
regarded by me as of Eocene age, and contemporaneous
with the fossil vegetable remains found abundantly intermixed
with the marine fossils of the Eocene age at Table
Cape.
