the Lower Ordovician limestones along the
Buskille to the contact with the Precambrian.
The dearly bedded magnesian limestones have
some sand and are interbedded with thin
banded once a few grey limestone that are
once a less in the form of intraformational
conglomerates. And gyes also have thin bands
of round grain sandstones and thin material
may also fill in the sun cracks. Towards
the bottom we saw a few gyes with crystals
from out or much in the typical form as
in banded crescentic layers of some lateral
extent. Between the their banded layers some
of the gyes are oolitic. All are once or
twice altered diagenetically. Barrell thought
that the alteration and cementation did
not take place beneath a constant cover of
water but rather under an alternate drying
and wetting conditions. According to our
creaking is due to aerial exposures under
monsoon conditions. The intraformational
