...Pierre Jutras; Grant M. Young; W. Glen E. Caldwell Abstract Because it is partly masked by a phreatic calcrete hardpan (PCH), a rare and poorly known type of rock that can transgress stratigraphic boundaries, there has been ongoing controversy concerning the exact position of James Hutton's first...

... and calcrete, with this example interpreted to have formed entirely within a semi-arid environment. Karst cavities were developed in a mature hardpan calcrete, generated in sandy fluvial sediments with associated aeolian deposits. Subsequent to karst cavity generation, clasts derived from the subaerially...

... and 10), including boulders of phreatic calcrete hardpan, may imply that the floor of the fault-bounded basin had a very irregular topography at the time of burial. It therefore seems that the dissection period during which the La Coulée Calcrete was partly eroded (Fig. 12C ) was interrupted by sudden...

...Pierre Jutras Abstract The Galdrings cliffs of Machrihanish, in the Kintyre Peninsula of Scotland, expose a Lower Carboniferous clastic succession that hosts a wide variety of calcretes, including thick and massive host-replacing phreatic calcrete hardpans (HRPCHs), which are geologically rare...

Syndepositional carbonate nodules are interpreted as calcrete, which occasionally coalesced to form extensive hardpan calcrete horizons. The vertical facies sequence...

.... A similar relationship is required for the Hardpan fault. The only strong constraint on the number of emplacement events and the possibility of overpressure along the SF thrust is the ‘jigsaw breccia’ described by Beutner and Hauge (2009) . That breccia indicates overpressure along the SF thrust...

Nevertheless, the exact extent of the toe is obscured southwest of the Hardpan Tear Fault (Fig. 2 ) beneath alluvium and younger Eocene Absaroka volcanic deposits, including the Deer Creek volcanic slide mass described by Malone (1994 , 1995 , 1996 ). The northeastern extent of the toe area terminates...

Approximately 20 km south of Neuhoff Reserve (Fig.  2 c), the Kamberg Formation hardpan layer on Asbaakies Farm ( c . 24°55.0′S, 16°20.0′E) is offset in a manner similar to that of the Hebron Fault scarp...

... with the named MFS Pg20. Minor unconformities and NE-trending faults of post-Miocene age resulted from the interplay of local diapiric salt movements in the Dukhan anticline and a regionally changing stress field. Extensional faulting was succeeded by a compressional phase that caused the reactivation of some...
