Diagenetic Responses to Sea Level Changes on Pleistocene-Holocene Carbonates in the Celebes Sea, East Sabah, Malaysia

Limestones are particularly susceptible to drastic early diagenetic modifications, either during or shortly after deposition or during periods of subaerial exposure. Tracing the depth to which the vadose zone penetrated along the sea level notch-opening and combining petrographic results, stable iso...
