Figure 3. Interpreted stratigraphy profile across Rhode Island Sound, modified from Needell and others (1983b). Stratigraphy includes: PzZ – pre-Mesozoic bedrock, Ku – mostly late Cretaceous coastal plain and continental shelf sediments, Qdo – mostly late Wisconsin glacial drift, Qdm – late Wisconsin moraine deposits, Qfe – Holocene transitional (fluvial and estuarine) deposits, Qpt – Holocene marine sediments. Contacts are dashed where inferred. Vertical exaggeration: 19X. Location of profile shown in fig. 1.
