“…The mid Holocene evolution of the borehole area is resulted from the detailed analysis of
five sedimentary units detected along the core Matar-1, and includes three distinct stages: (
a) from 5253 ± 223 y cal BP to 3138 ± 223 y cal BP, carbonate coarse-grained material consisting of coral fragments, molluscs, calcareous algae and benthic foraminifera are deposited on
a shallow marine fringing reefal platform, which becomes progressively
a nearshore backreef (around 3675 ± 215 y cal BP), and later (around 3138 ± 223 y cal BP)
a reef ramp; (b) since 3040 ± 220 y cal BP the borehole area obtains the characteristics of
a high-energy beach that receives increasing inputs of terrigenous material; (c) subsequently,
a supratidal backshore setting is established influenced mostly by terrestrial processes and occasionally by marine processes, as it is indicated by the
decreasing and sometimes sporadic presence of benthic foraminifera, and recently,
a sedimentary veneer consisting of terrigenous, carbonate and evaporite material is formed by terrestrial, mainly wadi and aeolian, processes. © 2018 Elsevier Ltd and INQUA…”
