Fig. 5: Comparison of observed and calculated gravity and magnetic anomalies along Transects D4 and D1 (Fig. 1).
From: Geophysical imaging of ophiolite structure in the United Arab Emirates
The data along the transects have been projected on to two different profiles: for transect D4 we used an azimuth of 90.0o and an origin located at 55.64oE and 25.50oN and for profile D1 we used an azimuth of 113.5o and an origin located at 55.20oE and 25.61oN. a Comparison of observed magnetic anomaly (solid purple lines) to the calculated anomaly (red dotted line) assuming the same ophiolite bodies that cause the gravity anomaly also cause the magnetic anomaly (grey shaded in d). b Topography/bathymetry profile (solid brown line) showing the location of the onshore seismic stations. c Seismic P wave velocities derived from sea shots recorded at the stations. d Comparison of observed Bouguer anomaly (red points) and calculated anomaly (solid blue line) based on the bodies outlined in e. e Crustal model showing densities assumed in the calculation of the gravity anomalies. Filled red (Moho) and blue (base ophiolite) circles: selected depth converted receiver function positive (velocity increase with depth) and negative (velocity decrease with depth) polarity events respectively. Figure constructed using GMT45.
