Abstract

The structural evolution of the Larnaka Ridge is studied using high-resolution multichannel seismic reflection profiles and multibeam mosaics of the seafloor. Multibeam maps revealed the presence of two families of enechelon tension cracks (young and old) on the seafloor north of the ridge. Rose diagram on the young tension cracks revealed that most lineations are oriented NW-SE, where the instantaneous tensile sigma 3 is oriented NE-SW. The old tension cracks are oriented N-S, here the instantaneous tensile sigma 3 is oriented E-W. In addition, the seafloor in the Latakia Basin and over the crest of the Latakia Ridge includes by several prominent ridges and their intervening valleys, forming four groups of seafloor lineations, each having a distinctive orientation, including ENE-WSW, ESE-WNW, NE-SW and NNW-SSE.
