Using foliation inflection/intersection axes investigates orogenesis: Take Arkansas River region, USA for example
面理弯切轴测量技术在造山带研究中的应用——以美国阿肯色河地区为例

The measurement of foliation inflection/intersection axes (FIA) preserved within porphyroblasts, have revealed much more extensive histories of deformation and metamorphism than previously recognized during the study of orogenesis. FIA data have been applied to solving many geological problems, such as investigating tectonometamorphic histories; correlating multiple phases of metamorphism on local and orogenic scales; studying porphyroblast nucleation and growth relative to deformation; reconstructing plate motions; constraining age dates; defining complex deformation partitioning patterns; and investigating pluton emplacement mechanisms and timing. This paper main focused on the significance of FIA data, the measurement of FIA and how it can be applied to solving geological problems. Take Arkansas River region, USA for example to interpret the application of FIA measurements in regional and detail study of deformation process during orogenesis.
