Stratigraphy comments: STRATIGRAPHIC RELATIONS: From unnamed Late Quaternary marine deposits. AGE: Pleistocene. No basis for age given in text, but presumably is based on macrofaunal biostratigraphy and stratigraphic position. STRATIGRAPHIC POSITION: Succession is situated about 2ยท3 meters above the present low tide, and built of a basal conglomerate with algal-limestone concretions followed by 0.80 to 1.50 m of fossiliferous beach sands. |
Lithology and environment
Primary lithology: | concretionary lithified calcareous conglomerate |
Secondary lithology: | shelly/skeletal sandstone |
