The Red Rock is actually chalk – the red colour comes from iron pigments. The red chalk is very rich in fossils (including ammonites and belemnites). The top of it, and the base of the overlying white chalk, are bioturbated by shrimp burrows. The white chalk was also laid down in deep marine conditions. It consists of a series of distinctive ...The sandstone formations were described as ranging from clean to very shaly. The formation factor was determined at a water resistivity of 0.01 ohm-m since, at that value, the apparent formation factor approached the true formation factor when the rock contained low-resistivity water. From their data, the following equation was provided:The Whitehill Formation of the Ecca Group is mainly made up of shale and chert. Therefore, the formation was not studied for modal compositional analyses. Clay minerals within the sandstone units and the whole rock analysis were determined by X-ray diffraction (XRD). The XRD result was used to confirm the petrographic framework.Sandstone formations contain Fluoride Ion (F-) in some form.
