Structure of the sheeted dike complex of the Samail ophiolite near Ibra, Oman
Abstract
The sheeted dike complex is a regionally mappable geologic unit with a consistent position in the Samail ophiolite stratigraphy. Discontinuous exposures of the complex in the Ibra area of the southeast Oman Mountains provide structural data that allow reconstruction of a paleo‐spreading ridge axis of 347° for the region and suggests a maximum spreading width of 275 km for the ophiolite. Contact relations within the well‐exposed Al Ahmadi section indicate that the complex was formed by multiple parallel intrusion over a narrow zone at the paleo‐ridge axis. Split dikes are abundant; facing directions indicate a spreading ridge southwest of the present outcrop area, in conflict with other spreading axis direction indicators.

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.
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.
