brief description and historical notices of the Island of Jersey, ... For the use of occasional visiters.
Concealed by the Tertiary deposits are Paleozoic and Mesozoic rocks that are overthrust by Precambrian crystalline rocks that form the core of the uplift Hausel, 1989. 00 Stratigraphic cross section of Mississippian through Lower Cretaceous rocks across central Montana from the fold-thrust belt to the Williston Basin Gunderson, J.
Members 1 to 3 contained most of ore mined in the Gilmore Texas mining district.
00 Geology of the Butte North 30' x 60' quadrangle, southwest Montana Scarberry, K. Tentative identifications of ATRYPA, CYRTOSPIRIFER, AUACELLA, PRODUCTELLA, GRAMMYSIA and PALEONEILO about 75 ft below top of Jefferson in Hyalite Canyon south of Bozeman suggests that these beds may be upper Chemung equivalents and upper age limit may be younger than given by Cooper et al 1942. In Box Elder County, northeastern UT, and Oneida County, southeastern Idaho, Jefferson Formation divided into ascending : Samaria Limestone Member newlimestone with minor orthoquartzite, sandstone, and siltstone, thickness 597 feet; and Hyrum Member.
00 Hydrogeologic investigation of the North Hills study area, Lewis and Clark County, Montana, Technical Report Bobst, A. Uranium, being soluble in the oxidized state but not in the reduced state, is readily leached from the oxidized rocks and deposited in zones where geochemical conditions change from oxidizing to reducing Lowry and others, 1993.
Of the consolidated Quaternary deposits, particular attention is given to the Quaternary volcanic rocks composing the Yellowstone Plateau.
Although unconsolidated deposits, commonly being quite permeable and often located along streams, are likely to be important for understanding hydrology and water quality, they are not further discussed in this section because their spatial heterogeneity is so great that brief treatment is of minimal value.
00 Hardin--Top of the Kootenai Formation Bergantino, R. 00 Synoptic groundwater sampling on the Ashland Ranger District Meredith, E. Source: GNU records USGS DDS-6; Denver GNULEX. Frontier strata in the western Centennial Mountains are structurally isolated from other Cretaceous rocks in the region and are part of the Lima thrust sheet that lies at the leading edge of the Sevier-style overthrusting in this part of southwestern Montana and adjacent southeastern Idaho.
A generalized composite of the outcrop maps is shown in. To sort the records displayed by a particular column, click on the column header.
Best exposed along Rattler Gulch; from here strikes northwest to Tenmile Creek. 00 Wolf Point -- Top of basal Colorado Bergantino, R. Most of the strong earthquakes in the study area have occurred in the vicinity of Yellowstone National Park, where the Yellowstone caldera lies at the apex of a parabola-shaped zone of seismicity with the axis centered on the eastern Snake River Plain of Idaho Smith and Braile, 1993.
00 Ekalaka--Thickness of the Judith River Formation Bergantino, R.
Geology This NASA LANDSAT II mosaic was compiled from 14 separate satellite images taken from an altitude of 565 miles or 900 kilometers during the summer of 1978.

The apparent absence of other Oligocene deposits suggests that during this epoch of the Tertiary the present Great Basin may have been high land and at least as well drained as during the Eocene.
Furthermore, the basal beds of the Navajo, locally at least, overlie with gradational contact the middle member of the Glen Canyon group, implying that the Navajo itself is not a synchronous unit.
