Reef flats are a particular type of marine terrace developed in inter-tropical environments as a result of bioconstruction as opposed to marine erosion processes that are selected according to the type of material available for dating as well as stratigraphic considerations.
Because they are relatively easily dated, marine terraces are often used as geomorphic sea level markers When the inner margin of the terrace is clearly identifiable (e.g.
In case of lower uplift rates, marine terraces can have a polycyclic origin because shorelines of different interglacials could to be superimposed if their eustatic levels were similar.
They typically occur either lying on the surface of the ground or buried within sediments such as alluvium, colluvium, or glacial till.
A weathering rind represents the alteration of the outer portion of a rock by exposure to air or near surface groundwater over a period of time.
This is done by comparing the thickness of weathering rinds of gravel composed of similar rock types.
Electron Spin Resonance Dating, or ESR dating, is a technique used to date newly formed materials, which Radiocarbon dating cannot, like carbonates, tooth enamel, or materials that have been previously heated like igneous rock.
