Stratigraphy and Petrography of the Cover Rock.

’ All the -strata of 'the cover rock aire practically
horizontal, and, as revealed by the borings, comprise, in
addition to marine alluvial sands, clays, iron ores, etc.,
diluvium, tertiary, chalk and permo-trias. In respect of
the diluvium and tertiary, the conditions differ in the
eastern, Meuse district and the Western Valley of the

Campine, for whilst both mostly overlie the chalk, they
also; in the east, lie immediately above the carboniferous..

Diluvium..—^This formation comprises Flandrian,
Hesbayan, Campinian and Mosean. From the data
obtained from the different boreholes, it would, appear
that the section of -the diluvium is very patchy, as the
result of-extensive abrasion, the Flandrian having been

found in only 10 holes, and the Hesbayan in two, though
the Campinian and .Mosean are more frequent. No
definite increase or decrease in the thickness of the
diluvial strata can be traced from east to west, though
an irregular increase is observed from south to north.

Tertiary. — This plays an important ' part in the
Campine, its thickness determining that of the cover
rock as.a whole.' In the western portion of the Campine
the deposits are entirely marine, but round the Meuse
they are brackish and with brown coal. Of the various
stages, Pliocene, Miocene, Oligocene, Eocene, ■■ and
Palasocene, the last-named only occurs in one borehole.
In the eastern section of the Campine the Eocene is
entirely absent. The most frequent series encountered
