Journal of the Geological Society (2014) 171 (2): 227-238.
... document push-up inversion structures versus fault-bend reactivation anticlines occurring along oblique thrust ramps, by examining examples of buried Apulian structures in the Central–Southern Apennines and outcropping thrust-related folds in the Central–Northern Apennines of Italy. The different geometric...

..., we can choose a very small β and try to fit all of the details in the data. Doing this, we obtain the results shown in green in Figure 2 . When we push the inversion to fit the (noisy) data very closely, we end up fitting the noise. To do this, conductivity contrasts are exaggerated...

... deposits are cut by an en echelon array of right-stepping, ENE-trending strike-slip faults that bound NW-trending push-ups and indicate left-lateral surface rupture ( Fig. 7A ). The second case is from above a north-dipping fault underlying the Dongping anticline, south of Borehole DP9 ( Figs. 2 and 7B...

... generating the high-frequency structure that is characteristic of fitting noise in the data. The AeroTEM data are visibly noisier than the other two data sets, so a higher uncertainty of 2 nT was used. Our mesh for inversion consisted of a core region with 20 m cubic cells that was padded with cells...

... the structures (inside the rectangles) indicate the presence of lateral heterogeneity associated with the channel fills. Pull-up and push-down anomalies caused by high and low velocities, respectively, in channels or carbonate reefs are also observed in other hydrocarbon-producing regions, such as the Middle...

... a half-graben (Figure  8 ). In contrast, Emma is a more symmetric push-up feature composed of a complex assemblage of conjugate thrust-related folds derived from the reactivation of conjugate normal faults that bounded a Triassic-Jurassic graben (Figure  11 ). Our reconstructions on these structures...

... margins such as the Vøring Basin and possibly the Faeroe Basin have a lower compressional strength than lower plate margins such as the Møre Basin, and therefore preferentially developed inversion structures. Along the transform boundaries separating the domains, additional stress probably built up along...

This robust dataset enabled documentation of focused tectonic activity in two competing low-relief basement structures to the east and west...

... and structural patterns during basin inversion. The selected experiments are representative of two possible tectonic configurations. In the Type I model, we investigate the influence of along-strike variations produced by differential extension in a wedge-shaped rift basin where extension increased from a pivot...

... pull-up/push-down, as well as small processing and velocity errors in seismic imaging. As a result, the chance that an interpreter will suffer a pitfall is inversely proportional to his or her experience. Interpreters with a history of making conventional maps from vertical seismic sections will have...

... logging data of a future SAGD site, where we simulate data from single and multiple surface loop transmitters. We have found that even when measurements are restricted to the vertical component of the electric field in standard observation wells, if multiple transmitters are used, the inversion recovers...

Predictions up to 2 Hz were asked for four different structure wave-field configurations (point source and extended source, with and without surface topography). This effort is part of a larger exercise organized for the third international...
