The boulders are also diverse in terms of lithology of the primary deposit. Some are silicified sands, with well visible cross-bedding or horizontal lamination, but the majority is made of a conglomeratic variant, with flint and chert gravels cemented by silica. On some boulders sharp or gradual transitions between the two variants may be observed.These carbonate rocks contain variable amounts of chert, and are often interbedded with fine grained, fragmented (clastic) rocks.
