Paleozoic deposits in Syria have been defined only in the subsurface according to the results of sparse and scattered deep exploration wells. Recently, Carboniferous deposits have been drilled more intensively in the Central Palmyrides within the INA's exploration concession. In Syria, Carboniferous deposit belong to Markada Formation and consists of thick clastic portion of intercalated siltstone/claystone/shale/sandstone with a few carbonate layers in the upper part and relatively thick regionally present carbonate layer in the lower part. Markada Formation can be considered to be one cycle as it lies between important regional unconformities (Devonian unconformity at the base and Permian unconformity at the top). The thickest Carboniferous deposits are preserved between paleo uplifted highs, up to 2000 m is in the Palmyrides. Basin orientation was NW-SE , bathymetry and geometry were changeable, according to the sea level fluctuation, climate oscillation and tectonic subsidence. Presumption is that the source area was within southern granitic provinces (Arabian shield) from where, eroded material was via deltaic/river system transported to the shallow shelfs and epiric seas on the Gondwanaland. The depositional environment was transitional from continental to near shore marine setting. Thick carbonate layers in the lower part represent MFS, C10 (SHARLAND et al., 2001.) while clastic deposits above are mainly regressive with periodical marine intrusions and were deposited as small delta distributory mouth bars and/or meandering tidal channel sands that merged and pinched out laterally. Markada sandstone layers in the upper part of the formation in the Palmyrides are gas and condensate bearing (average porosity 10%, TOC 0.3-0.69%) and so far are representing the main exploration target within Paleozoic deposits.
