Structural control of breccia pipes on the southern Marble Plateau, Arizona

The potential of breccia pipes in the National Tank Aream, Hualapai Indian Rreservation, Arizona

“…3). This density of collapse features is not unique to the Hualapai Resexvation, the western edge of this pipe-rich region in Arizona, but extends eastward where a similar concentration of pipes had been mapped earlier on the Marble Plateau (Verbeek and Wenrich-Verbeek and Verbeek, 1980;Sutphin, 1986). Thus, throughout the paper the tenns solution collapse, stiUcture, or feature are defined as those areas that apparently collapsed due to dissolution of any underlying rock, whereas the tenn breccia pipe refers specifically to dissolution of the Redwall Limestone, which resulted in stoping and brecciation of the overlying rock…”

Laccolith complexes of southeastern Utah: Time of emplacement and tectonic setting — Workshop proceedings

“…The existence in parts of the region of conspicuous linear belts of pipes led to repeated suggestions that pipe positions were influenced by underlying structure, possibly of basement origin (Sutphin and others, 1983;Sutphin and Wenrich, I 983;Sutphin, 1986). The nature and extent of that influence, however, remained conjectural.…”

“…Breccia pipes on the Marble Plateau are well exposed and were first described in detail by Sutphin (1986). Recent fracture work includes a field study of joint networks at 18 localities (Sutphin, 1986), detailed photogeologic mapping of fracture traces across large tracts of exposed bedrock (E.R. Verbeek, unpub.…”

“…The breccia pipes of this area were extensively investigated by Sutphin ( 1986), who mapped 90 of them and interpreted them as solution-collapse -features related to Mississippian-age caverns in the Redwall Limestone. The common presence of pipes in Late Triassic strata of the Chinle Formation, the youngest bedrock unit preserved in the area, shows that the upper parts of some pipes formed 100 m.y.…”

Ground magnenometer surveys over known and suspected breccia pipes on the Coconino Plateau, northwestern Arizona

“…Huntoon (1986) discussed breccia pipe hydrology and provided good evidence for ascending mineralizing fluids. There is evidence for the structural alignment of pipes, especially on the Marble Plateau, and this is presented in Sutphin (1986) and in Wenrich (1983, 1986). This evidence for breccia-pipe alignments on the Marble Plateau was evaluated by Wheeler (1986).…”
