The BIF and strongly altered BIF/schist package are located within a folded stratigraphic sequence
with mafic mudstone and siltstone which also contain sedimentary breccia horizons that can be weakly to moderately silicified, pyrrhotite mineralized, and carry anomalous gold mineralization.
Then move on to Ilston to examine "ice-house" deposits in order to contrast them with the "greenhouse" stratigraphic sequence
seen in the morning.
Inhumations and the Matrix: The value of stratigraphic sequence
in ancient burial sites.
However, the rotational movement also involved the rest of the overlying stratigraphic sequence
of limestone and marls, which is 150 m thick, and clays and marls, about 30 m thick.
1A), which defines major erosional interfaces and systematizes vertical traceability of known faults according to the stratigraphic sequence
. This allows the definition of fault displacements and sets limits to the distribution of the sedimentary layers.

in carbonate platform and slope: empirical models based on microfacies analysis of Paloogene deposits in southeastern Spain." Palaeogeogr Palaeoclimatol Palaeoecol, 155: 211-238.
The stratigraphic sequence
of the Niger Delta comprises three broad lithostratigraphic units: a continental shallow massive sand sequence--Benin Formation, a coastal marine sequence of alternating sands and shales--Agbada Formation, and a basal marine shale unit--Akata Formation.
The style of mineralisation, within a sheared siltstone/sandstone host, appears to differ from the currently identified resource to the north, although it is interpreted to occur in the same stratigraphic sequence
. The core will be prioritised for assay which may take approximately 2 months before results are available.
The use of both a broader perspective and exposure, in conjunction with the "Kenyon-Wheeler" system of developing a stratigraphic sequence
described in chapter eleven (D.
