Article Abstract:
It is true that the Sevier Desert reflection is just a hypothesisto be examined. The study gathered data for fault-related deformation insamples obtained from two boreholes across this feature. No data were gatheredconcerning cataclasis in the hanging-wall block and for ductile deformation in thefootwall. They will certainly alter the geologic interpretation of Sevier Desert.However, basic geologic data were not disregarded in interpreting the geology ofSevier Desert based on the new data gathered, nor are there any data that showthe need for a major low-angle normal fault.

Is the Sevier Desert reflection of west-central Utah a normalfault?: comment and reply
Article Abstract:
The ideaof a Sevier Desert detachment is more of a hypothesis that should be investigatedrather than a proven truth. Anders et al. disregarded geologic data showing thenecessity of a major low-angle normal fault on the east side of the SevierDesert basin. They studied microfractures in well cuttings to analyze zones ofdeformation. However, it is very hard to locate cuttings in depth and relate them toseismic time sections. They also failed to compare their data against thenumerous low-angle normal faults around the core complexes.

Western frontal fault of the Canyon Range: is it the breakaway zone of the Sevier Desert detachment?: comment and reply
Article Abstract:
Otton (1995) has proposed an interesting detachment model of the western frontal fault of the Canyon Range. However, his model fails to completely address the effect of Mesozoic tectonics on surface geology. Tertiary sediment records provide little evidence of a low-angle normal fault illustrated in the Otton cross-section. High-angle normal faulting and rotation provide better explanations of the Tertiary outcrop geology of the Canyon Range.
