| Description |
Brine in storm wave splash pool. This partially water-filled depression in developed on a near-earliest Holocene, ~9200 year-old calcrete (a.k.a. terra rosa paleosol). Calcretes are modern or ancient calcium-carbonate rich soil horizons that are rock hard. The term "terra rosa" refers to the rusty reddish coloration of iron oxide (hematite & limonite), which is typical of fossil soil horizons in the Bahamas rock record. Near-shore depressions such as this occasionally receive and accumulate ocean water from sea spray and crashing waves, especially during storms. Post-storm evaporation results in the water becoming a brine (= very high salinity water), followed by the precipitation of halite crystals (NaCl - sodium chloride) to form a slush (crystals + briny water). Further evaporation results in the formation of a halite crust or halite fill (no water left). Locality: near the rocky shoreline of Green Cay, western Graham's Harbour, offshore northwestern San Salvador Island, eastern Bahamas |
