Sections North of Ingenika River

North of Ingenika River, deformation has thickened some beds, thin-
ned others, and in the thick limestone sections caused an unknown degree
of repetition of beds by isoclinal folding. Consequently, any estimate of
stratigraphic thickness has little meaning in these areas, and, owing to the
lenticular nature of some of the deformed beds, the stratigraphic sequence
in any single measured section is only representative for a very limited area.

In the following sections, the stratigraphic thicknesses listed are those
observed in the field without special regard as to whether any particular
bed was measured at a place where it was thinned on the limb of a fold
or thickened by drag-folding. They are presented merely to show the
relative abundance of the various rock types, and the thickness given may
differ considerably from the average thickness of the beds to which they
refer.
