Summary:

Pg. 229-240. Bonanza King formation. Consists of (descending): (1) sandy dolomite and platy shale, thin; (2) light-gray, fine- to medium-grained dolomite, 200 to 225 feet; (3) Silver King dolomite member, 200 to 250 feet; (4) nodular and lenticular chert underlain by light- and dark-gray dolomite, 900+/-feet; (5) sandy, reddish, platy dolomite, 25 to 30 feet.; (6) light- and dark-gray dolomite and partially dolomitized limestone, 600 to 650 feet. Thickness of formation, 2,000+/- feet. Poorly preserved fossils in lower 100 feet in Providence Mountains indicate Middle Cambrian. Overlies Cadiz formation (Middle Cambrian) and underlies Cornfield Springs formation, in part at least Middle Cambrian. Occurs in Providence and Marble Mountains, San Bernardino County, southeastern California.
[Type locality:] exposures near Bonanza King Mine, on east side of Providence Mountains, San Bernardino Co., southeastern CA. [Mine in sec. 3, T. 10 N., R. 14 E., Flynn 15-min quadrangle, San Bernardino Co., southeastern CA.]

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


Summary:

At its type locality, age is considered Late and Middle Cambrian rather than wholly Middle Cambrian. The names Cornfield Springs and Bonanza King were misapplied [in the Nopah Range] by Hazzard (1937). Units formerly designated by these names in the Nopah Range should be considered as unnamed upper and lower divisions, respectively, of the Bonanza King.

Summary:

Bonanza King formation (Hazzard and Mason [1953]; Palmer and Hazzard, 1956) is adopted. At Bare Mountain unit shows many zones containing white to yellowish-gray very coarse dolomite.

Summary:

Lower contact of Papoose Lake Member of Bonanza King Formation raised 250 ft. This 250 ft now comprises part of subunit 7 (290 ft thick) of Carrara Formation since detailed lithology shows subnunit 7 is more like Carrara Formation with its shales and silty limestones.

Summary:

Mapped in Independence 15' quad, Inyo Co, CA in Mazourka Canyon, Inyo Mountains, where total thickness is more than 2800 ft. Described as varied gray, laminated to thick-bedded dolomite. Alternating light-gray and dark-gray layers (few inches to several tens of ft thick) give many areas "zebra striping". Spheroidal algal(?) structure (GIRVANELLA?) locally abundant in lower part. Upper few 100 ft more massive and buff colored. Assigned Cambrian age.

Summary:

Mapped in Inyo Mountains in extreme lower right corner of Blanco Mountain 15' quad, Inyo Co, CA. Consists of coarse-grained gray to buff dolomite, largely transformed to dolomite marble. Only lower part of unit, of Middle and Late Cambrian age, is present in map area.

Summary:

Pg. O17-O19, pl. 1 (geol. map). Bonanza King Dolomite. Consists almost exclusively of dolomite, in various colors and shades of gray, banded in layers from a few inches to a few tens of feet thick; exhibits a conspicuous "zebra striping." Present locally are a few thin beds of limestone; slightly argillaceous dolomite layers; and black chert in nodules and beds as much as 1 foot thick. Contains algal structures (GIRVANELLA?). At measured section, east of Bluebell mine, is divided into five distinct units on basis of color differences; total thickness about 2,800 feet. South of measured section, a distinctive black dolomite zone many feet thick occurs about 200 feet from top of formation, between uppermost massive unit and underlying striped sequence. This black dolomite is an excellent marker bed, and it can be traced for several miles to the south. Where delineated on accompanying geologic map, it is shown as a dotted line. Bonanza King crops out in a broad arcuate belt from north boundary of Independence 15-min quadrangle to vicinity of Barrel Spring. South from there, outcrop tails off to a thinner belt that extends nearly to mouth of Mazourka Canyon. Conformably underlies Lead Gulch Formation; conformably overlies Monola Formation. Tentatively assigned to Middle and Late Cambrian age, based on stratigraphic position and ages of correlative rocks in other areas.
[Name Bonanza King Dolomite is applied to correlative rocks in Inyo Mountains because lithologies other than dolomite are extremely scarce (citing Code of stratigraphic nomenclature, 1961, art. 15 (change in lithologic designation), p. 654).
GNC remark (1965, USGS Bull. 1244-A, p. A11): Bonanza King Dolomite used in report area. Bonanza King Formation in good usage elsewhere.]

Summary:

Mapped in upper plate of Last Chance thrust in lower left corner of Magruder 15' quad, Inyo Co, CA.

Underlies upper Cambrian Nopah Formation and its Dunderberg Shale Member; also [unconformably] underlies Miocene diorite of Last Chance Range. Age is Middle and Late Cambrian.
