Low-water intervals (signifying periods of drought) are recorded by carbonate-rich laminae containing abundant plant fossils indicative of hypersalinity. In contrast, highstands of relatively fresh water (outlining moist periods) are represented by massive, silicate-rich sediment with lower numbers of halophytic indicators. This content is PDF only.
