[Available online, with subscription, from AAPG archives: http://www.aapg.org/datasystems or http://search.datapages.com]


Summary:

Is restricted to about 2200 to 2300 ft of gray to brown quartzite disconformably? above the Stella Lake Quartzite and beneath the Pioche Shale. Stella Lake is named as the upper unit and one of six units removed from the Prospect Mountain Quartzite and reassigned to the McCoy Creek Group (new). Is a brown-weathering quartzite easily separated from the white, massive quartzite of the Stella Lake. A 2 ft thick fine quartz-pebble conglomerate succeeded by 1) a few inches of argillite, and 2) gray, rusty-brown weathering quartzite in beds 1 ft or less to 3 ft thick, that are cross-bedded. A 50-60 ft. thick brown, micaceous, fucoidal, slabby argillaceous siltstone and fine-grained quartzitic sandstone that is in turn overlain by 40 ft of white quartzite makes up the upper part of the Prospect Mountain. Geologic map; mapped in the eastern northwestern part of the southern Snake Range, White Pine Co, NV in the Great Basin region. Of late Precambrian age.

Summary:

Prospect Mountain quartzite is extended to the Snake Range, White Pine Co, NV, where two subunits are recognized: upper and lower sandy quartzite, middle argillite and sandy argillite. Unit is mapped as Cambrian, but explanation states that argillite and lower quartzite subunits may be Precambrian in age.

Summary:

Prospect Mountain Quartzite is geographically extended to the Pioche mining district, Lincoln Co, NV. In nearly all respects the quartzite at Pioche resembles closely that of the type area, and in both districts these strata conformably underlie Lower Cambrian strata containing OLENELLUS [trilobite]. Partial section (no base present) measured at about 2400 ft. Trace fossils (SCOLITHUS [SKOLITHOS]) present in upper part of formation. Age is shown as Early Cambrian. Columnar sections and correlation diagram included.

Summary:

Mapped in Dugway Range, Tooele Co, UT and in several small knolls to the northeast of the Thomas Range, Juab Co, UT in the Great Basin province. Mapped area lies between Oquirrh Range, UT to northeast where Gilluly (1932) mapped it and Drum Mountains, UT to southwest where Crittenden, Straczek, Roberts (1961) mapped it. Is the most widespread Cambrian unit in this part of Great Basin. Composed of white or tan massive quartzite and purplish-red quartzite, quartz pebble conglomerate, shale, and siltstone. Nearly 12,000 ft thick. Sequence varies from one fault block to another. Underlies Cabin shale. No diagnostic fossils found. Correlation with rocks of Precambrian age elsewhere not possible. Authors believe greater part of Prospect Mountain in Dugway Range is only Early Cambrian. Geologic map. Stratigraphic sections.

Summary:

Newly assigned as the upper formation (of four) to the Brigham Group in the Sheeprock Mountains of north-central UT in the Great Basin province. Section 785-1,350 m thick is well exposed in report area. Consists of white or gray, fine- to medium-grained, slightly to moderately feldspathic cross-bedded quartzite. Has even parallel laminations. Thin layers of pebbles in lower part. This quartzite was assigned by Cohenour (1959) to the Tintic Quartzite, but present author follows practice of correlating quartzite above the Tintic Valley Thrust with Prospect Mountain Quartzite of the Gold Hill area (Nolan, 1935). Overlies Mutual Formation of Brigham Group. Underlies Pioche Shale. Most of Prospect Mountain is Early Cambrian but lower part may be Proterozoic.

Summary:

Base and top of Prospect Mountain Quartzite not preserved in Elko Co, NV. Unit in Elko Co is assigned a presumed Early Cambrian age on basis of whole rock Rb-Sr age of 550 +/-30 Ma for metamorphic event that affected underlying schist but not the quartzite in Ruby Mountains, south of Elko Co (Kistler IN Kistler and Willden, 1969). This age assignment does not negate Stewart's (1974) conclusion that the unit in southern NV and southeastern CA [!] is of Precambrian Z and Early Cambrian.
