Some fossils. The depositional environments include beach, marsh and depositional environment and may contain varying amounts of minerals. The sands are poorly to well sorted depending on the percentages of organic matter. The sands may contain heavy composed of sands, silts and clays that sometimes contain varying Pleistocene and Holocene coastal deposits (Qph).
