The Latakia Ridge is a prominent northeast–trending
bathymetric high on the northern margin of the
Levantine Basin. It forms the easternmost segment of the
Cyprus Arc, linking the steep Hecataeus Rise south of Cyprus with a series of ridges off the
Syrian coast. Rising up to 500 m above the surrounding seafloor and extending over 200 km, the ridge delineates the present-day boundary between the
African and
Anatolian Plates. This structural high first developed in the mid–Late Cretaceous as a compressional fold–thrust belt during NW–SE convergence of the African and Eurasian plates, punctuated by emplacement of ophiolitic nappes and the formation of a Late Cretaceous regional unconformity. High-resolution
seismic reflection data reveal that the ridge's basement comprises deep-marine
sediments deposited from the
Eocene through the lower
Miocene. During the Miocene (about 23–5
million years ago, Ma), these strata were gently folded into long, asymmetric
anticlines—upward-arching folds—and
emplaced by southeast-directed
thrust faults, forming a classic
fold-thrust belt. This phase ended with regional
uplift and
erosion prior to the deposition of
evaporites from the
Messinian age. The weight of folding and
ophiolite loading flexed the
lithosphere north of the ridge, creating a
foreland basin that was filled by Late Cretaceous to Eocene deep-water
marls and
shales, whose onlapping reflections mark key seismic horizons. From the
Pliocene (about 5 Ma) to the present, the ridge was reworked by oblique,
sinistral (left-lateral)
strike–slip motion. Reactivation of the earlier thrusts, together with new back-thrusts dipping in the opposite direction, produced a narrow pop-up geometry known as a positive flower structure. This
transpressional regime is recorded by
onlapping and thinning of overlying Plio-Quaternary sediment layers on both flanks of the ridge, marking simultaneous uplift and deposition during active faulting. ==Hydrocarbon prospectivity==
