Summary:
Gardiners Clay is here restricted to marine clay containing fossil assemblages that indicate sea-water temperatures somewhat warmer to somewhat cooler than present sea-water temperatures off Long Island. Unit lacks radiometric ages, but Stone and Borns (1986) reported AAR age estimates of 80 to 130 ka. Belknap (1980) reported AAR age estimates that indicated both isotope stage 5 and isotope stage 7 to 9 ages for the shells in the Gardiners clay. Age then is inferred to be Sangamonian. Stratigraphically underlies the Montauk Till Member of the Manhasset Formation, which is everywhere faulted and folded making it difficult to establish its stratigraphic position relative to under and overlying deposits. The Montauk is here interpreted to be Illinoian.
