Very good, Tau. My sense suggests to me that the finely-bedded bluish rocks are silt- or mudstones. Fine particle sizes that remained in suspension and settled away from the early delta. The purplish rocks are a different mineralogy and are somtimes associated with the siltstone units, which may well.be cyclic. Some purplish rocks appear to be coarse grained and may represent rocks that have tumbled down from higher in the section, or may represent cataclysmic flows in the streams or may represent turbidites from the delta. The mineralogical difference may be the result of intense chemical weathering of volcanic rocks in wet basins of the upland that were breached during intense rainfall events and entered the streams as a slug.
