... east. The Madison limestone of lower Mississippian age and the Deseret and Humbug formations of upper Mississippian age maintain fairly constant lithologic character along the west and north sides of the Uinta Basin, but the aggregate thickness of the three formations decreases from about 1,800 feet...

...Jeff Dejarnett ABSTRACT Mississippian strata at Mt. Darby comprise the Madison Group and the overlying Humbug Formation. This sequence, although initially transgressive, exhibits an overall regressive character produced by progradation of platform carbonates in response to sea level fluctuations...

..., the following formations are exposed in sequence westward: Swan Peak Quartzite, 300+ ft (91 m); Fish Haven-Laketown Dolomite sequence, 1,540 ft (470 m); Water Canyon Formation, 455 ft (138 m); Jefferson Formation, 1,230 ft (375 m); Beirdneau Formation, 990 ft (300 m); Lodgepole Limestone, 330 ft (100 m); Humbug...

... suggest that evaporitic strata equivalent to the Charles Formation once were widespread. Sandstone and shale are present in the Humbug Formation (Meramec) and in the lower part (Chester) of the Manning Canyon Shale in northeastern Utah. Pennsylvanian rocks display marked local diversity of extent...

..., Leadville, Redwall, Humbug, and Manning Canyon formations. The Humbug and Manning Canyon formations are present only in the northwestern part of the area, due to erosion of the Humbug and the fact that the Manning Canyon was deposited only in the area of the Oquirrh basin of central Utah. At the close...

..., and evaporites, occupies a stratigraphic interval between that of the Hermosa formation of southwest Colorado and that of the thick Oquirrh formation of north-central Utah. The Mississippian in the region is largely Madison in age, although Upper Mississippian rocks are probably present. The Humbug formation...

... the Vondergreen Hill Peridotite (new name), were emplaced. Tectonic lands probably rose by differential movements related to wrench faulting. Coarse gravels of the Humbug Mountain Conglomerate (new name) and, later, progressively finer sediments of the Rocky Point Formation (new name) were shed...

... thickening of black shale at the expense of limestone in the Great Blue-Manning Canyon succession between the Oquirrh Mountains and Provo. Furthermore, Crittenden (1959) indicated a questionable unconformity between the Doughnut (Great Blue) and Humbug Formations in the Morgan area and elsewhere...

... ). Deeper zones such as the Nugget and Weber Sandstones or sands of the Mississippian Humbug Formation are largely untested in this area ( Skeeters and Hale, 1972 ). The Paleozoic section expected is essentially that exposed near Morgan, Utah ( Mullens and Laraway, 1964 ; Mullens, 1967 ), in which a thin...

.... From Willard Canyon to North Ogden Canyon, the thrust fault cuts the Maxfield Limestone. Between North Ogden Canyon and Ogden Canyon, the Willard thrust ramps gradually upsection laterally to the Mississippian Humbug Formation and is underlain by a large recumbent syncline overturned to the east (see...

... geochemistry of Mississippian rocks in the Lakeside Mountains, formations that are stratigraphically well above the type area of the Delle event were sampled. These include a rhythmically bedded lime mudstone within the Humbug Formation (Upper Meramecian) and crinoidal limestone beds from the base of the Great...

I have never dreamt that a special issue of such a prestigious journal as the Canadian Journal of Earth Sciences filled with such distinguished names...

Fine-grained sandstone in the lower part of the Brazer, now named the sandstone member of the Little Flat Formation, is the stratigraphic equivalent of the Humbug Formation to the southwest, The Humbug is slightly thicker and coarser-grained than the sandstone member of the Little Flat...

... of the “Humbug intercalated series” of the Tintic mining district ( Tower and Smith, 1899 ), later redefined as the Humbug Formation in the Oquirrh Mountains by Gilluly (1932) . The Humbug Formation is overlain by the Upper Mississippian Great Blue Limestone, also named by Gilluly (1932) . The Great Blue...

... positioned between the Cambrian Tintic Quartzite and the Carboniferous (Mississippian) Humbug Formation. This was a different Eureka Formation than the Eureka Quartzite proposed by Hague (1883) for quartzites in Nevada and western Utah. Tower and Smith's (1899) Eureka Formation was later renamed...

The trip by steamboat to his destination was complicated since the steam-powered vessel had to ascend the rapids above Keokuk. After some difficulties, Koch reached his objective...
