The
original data obtained from the reference scribelines are computed and
restored in their real spatial position by a reorientation process taking
in account the orientation data.
The cores are
grooved by three knifes as they are going into the core barrel. These
knifes are separated by three different angles (100°, 120° and 140°),
and one of them is the reference groove. This groove will be used as reference
line to make the measurement of the structures on cores (the reference
line drawn on the cores is oriented in reference with this groove).
A multishot instrument
is set within a non-magnetic collar above the core barrel and aligned
with the reference groove. Survey data are shot throughout the course
of coring providing orientation of the entire core.
The tectonic and
sedimentary data picked up in reference to the orientation groove are
replaced in geographical position by using the core orientation data that
are delivered in a tabular format with the depth.
