Crustal structure of the northern Levant region: multiple source Werner deconvolution estimates for Bouguer gravity anomalies
Open accessAbstract
The opening of the Gulf of Aden and the Red Sea, and the collision of the Arabian plate with the jigsaw southern margin of the Anatolian plate have sheared the Sinai-Levant microplate off the NW part of the Arabian plate, and created the left-lateral Dead Sea (Levant) transform fault. The structural setting of the northern Levant region, particularly Lebanon and the Palmyrides, has been complicated by detachments along incompetent evaporitic horizons, roughly separating the post-Triassic succession from the underlying crustal material. The interpretation of the multiple source Werner deconvolution (MSWD) estimates of Bouguer gravity profiles, which were separately calculated for Syria and Lebanon, integrated with the available geological and geophysical results leads to the following interpretations: (1) the crust of Syria thickens southeastwards from approximately 32 km under the Al-Ghab Graben to >36 km under the Aleppo high, the Palmyride fold belt and the Rutbah high; (2) the lower-crustal (basaltic) layer thickens northwestwards from the hinterland to the Al-Ghab graben at the expense of the overlying andesitic layer; (3) the Mid-Beqa'a fault is delineated by the MSWD estimates in Lebanon and its NE extension in Syria; (4) the Phanerozoic section in the southwesternmost parts of the Palmyrides is ∼ 13 km thick, and the shortening there could exceed 30 km; (5) the Palmyride fold belt, and the Serghaya and Mid-Beqa'a faults could have accounted for about 70 km of the 105 km left-lateral displacement along the southern segment of the Dead Sea transform fault system, without transmission to the Syrian (northern) segment of the fault system; (6) the splitting of the Dead Sea transform fault in the Kuleh Depression into the Serghaya. Mid-Beqa'a, Yammouneh and Roum faults could be explained by the rotation of the detached post-Triassic succession over a stable deep left-lateral fracture of the Dead Sea fault in the underlying crustal material.

Seismic-refraction results from Syria show that the Phanerozoic sedimentary section varies from more than about 8.0 km in the Rutbah high to 9.0 km in the NE Palmyrides and 11 km in their central part.
“seismic-refraction results from Syria show that the Phanerozoic sedimentary section varies from more than about 8.0 km in the Rutbah high to 9.0 km in the NE Palmyrides and 11 km in their central part (e.g.Seber et al. 1993;Barazangi et al. 1993).”

The Abstract (page not provided) places the approximately 11 km sedimentary section in the southwestern Palmyrides and the approximately 9 km section in the central belt—not 11 km centrally and 9 km in the northeast. It does support a basement depth of at least 8 km in the Rutbah uplift. The Profile II passage also says the 11 km column includes pre-Cambrian sedimentary rocks, so calling the entire column Phanerozoic is not supported. (LLM, conf=0.88)

The Shortening section reports minimum shortening estimates of 20 km, 3 km, and about 1 km from southwest to northeast, supporting the southwestward increase.

The Discussion reports basement depths of about 9 km in the central Palmyrides and 11 km beneath the southwestern segment, consistent with a thicker sedimentary column to the southwest. But Profile II says the 11 km column includes pre-Cambrian rocks, so the paper does not establish that the Phanerozoic section itself reaches 11 km. The supplied passages give no basis for assessing “over almost the same distance.” (LLM, conf=0.86)

The paper relies on this without support.
The vertices inferred by MSWD correspond to real geological interfaces (e.g., Moho, basement, basaltic/andesitic boundary).
“The interfaces of the proposed models were basically assigned by the location of the vertices, taking into account the results of earlier geophysical studies and the regional geological elements, particularly the faults and their extensions.”
The paper relies on this without support.
The 2-D gravity profiles are representative of the 3-D crustal structure of the northern Levant region.
“All profiles extend from the Mediterranean shoreline in the west to the southeastern borders of Syria with Iraq and Jordan (Fig. 3).”
The paper relies on this without support.
The bulk of the Triassic system consists of dolomites and limestones with less common cyclically repeated shale and evaporite beds.

Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
BB′ results cite the wrong figure
MinorThe paper places the Lebanese BB′ MSWD estimates in Fig. 7c, but the discussion of those estimates cites Fig. 8c.
“The rectangles of MSWD estimates along profile BB' (Fig. 8c) probably depict vertices at the basement surface between the coastline area and Anti-Lebanon.”
“Figure7.MSWD estimates for Bouguer gravity anomalies along the Lebanese segments of profiles, AA' (a), BB' (c) and CC' (e).”
Conflicting lower bound for sediment thickness in Lebanon
MinorThe AA′ results give a lower bound of 3.5 km beneath Mount Lebanon and the Anti-Lebanon Mountains, while the concluding summary gives 4.5 km for those same areas.
“These vertices indicate that the Phanerozoic sedimentary section varies from 3.5 to 7 km under Mount Lebanon and the Anti-Lebanon Mountains to about 10 km under the Beqa'a Valley.”
“In Lebanon the thickness of the sedimentary section varies from 4.5-7 k m beneath Mount Lebanon and the Anti-Lebanon t o about 9 km beneath the Beqa'a Valley.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
