... as early Miocene show the arcuate form. The strike of tilted beds, fold axes, and in places elongate plutons, parallels the trend of the arcuate ranges, herein called “oroflexes”—defined as mountain ranges with arcuate trends that result from tectonic bending of the crust. The gross structural pattern...

...ABSTRACT ABSTRACT The problem of how map-view curves (variously named salients, recesses, arcs, oroclines, virgations, festoons, bends, oroflexes, and syntaxes) in fold-thrust belts originate has caught the attention of geologists for more than 200 years. This chapter reviews the advances...

... trend (oroflexing) of the older marine magnetic strip anomalies. Thus the normal faults, now some distance from the spreading axis, were rotated up to 40° clockwise with the anomalies and now have a component of strike-slip as shown by earthquake focal mechanisms. And just as we observed in the Imperial...

... bends, coupled, or multiple bends ( Johnston et al., 2013 ). Earth scientists have referred to plan-view curvature of mountain belts with different terms, including orocline, arc, syntaxis, curve, bend, virgation, salient, festoon, arcuate range, oroflex, or recess ( Marshak, 2004 ). The term...

.... 3 Dunlap strata in the Hawthorne and Tonopah quadrangles strike nearly east-west and could have been rotated as much as 90° about a major fold (the “oroflex”) hypothesized by Albers (1967) to encompass much of west-central Nevada. “ Thrust conglomerate ”.—Critical relations cited...

..., linear valleys of north-northwest trend that are outlined by pronounced thoroughgoing structures with abundant evidence of Holocene and local historic faulting.” He contrasted this tectonic pattern with the display of “adjacent transform-like offsets or large-scale oroflexing common to many elements...
