Testing Laramide Hypotheses for the Front Range Arch Using Minor Faults: Reply

摘要

I apologize to the readers of The Mountain Geologist and to my coauthor, Scott Larson, for my misrepresentation of the contributions of Boos and Boos (1957) and Matthews and Work (1978). I agree that Boos and Boos (1957), while reinterpreting some faults in the northeastern Front Range to steeper angles than some previous authors, did discuss thrust faults to the south and west. Matthews and "Work (1978), in contrast, did not consider the implications of structures outside the northeastern Front Range, My offending sentence should have read "Near vertical dip slip was proposed on the higher angle, range-bounding faults of the northeastern Front Range Arch (Fig. 3a; Boos and Boos, 1957; Matthews and Work, 1978), a hypothesis that might be compatible with the low-angle, older-over-younger faults on the western margin of the arch if they were gravity slides." These errors are due to my attempt to concisely summarize previous papers in a necessarily limited space.
