    The formation is moderately fossiliferous and Palmer and Halley () have assigned an age of early Late Cambrian through the early part of the Middle Cambrian Glossopleura Zone. An excellent uncomplicated and easily accessible section of the Carrara Formation is located in Emigrant Pass in the southern part of the Nopah Range.

M. and J. W. Hagadorn. Unusual Lower Cambrian fossils from the Latham Shale: What, if anything, is a Lagerstatten? House Range, Utah - A varied array of Cambrian critters has been found in the Wheeler Shale and the Marjum Formation, both of which are exposed in the House Range. Marble Mountains - In the hottest part of the Mojave Desert of California is the rich Latham Shale where Olenellid trilobites are numerous.

    Displaced uppermost Precambrian to Lower Cambrian miogeoclinal strata occur within Snow Lake pendant in the central Sierra Nevada. These rocks have been correlated with the Stirling Quartzite, the Wood Canyon Formation, the Zabriskie Quartzite, and the Carrara Formation in the western Mojave Desert and the San Bernardino Mountains (Lahren and Schweickert, ; Lahren, ). The Gog Group is a stratigraphic unit in the Western Canada Sedimentary is present in the western main ranges of the Canadian Rockies in Alberta and British Columbia, and in the Cariboo Mountains and in the central Purcell Mountains in southwestern British Columbia. It was named by C.F. Deiss in for a type locality near Mount y: Canada.

A total of 18 formations comprise the middle Cambrian (Series 3) succession of the West Desert and, together, they span the entirety of the series, with the Eokochaspis through Cedaria trilobite. The Lower Cambrian Wood Canyon Formation, recognized over a 39, km 2 belt through the southern Great Basin and Mojave Desert, was examined in the southern Marble Mountains, eastern Mojave Desert, southeastern California.

There it crops out as a well-exposed m thick, feldspathic sandstone nonconformably overlying Proterozoic by: The Early Cambrian Zabuk Formation of orthoquartzites and siltstone of continental origin is followed conformably by the Middle Cambrian Burj Formation of shallow marine dolomitic limestone with thin shale intercalations, which were penetrated in well Khanasser-1 in northeastern Syria.

The Hongjingshao Formation (Cambrian Series 2, Stage 3), a unit between the Yu'anshan and Wulongqing formations (Fig. 1A), is dominated by reddish-purple, medium to thick-bedded sandstone, interbedded with thin-bedded mudstone that yield shelly fragments and parts of biota present in the Hongjingshao Formation represents an evolutionary link between the older Chengjiang Author: Yi Ding, Jian-Ni Liu, Yan Liu, Fei-Fei Chen.

The International Commission on Stratigraphy list the Cambrian period as beginning at million years ago and ending at million years ago.

The lower boundary of the Cambrian was originally held to represent the first appearance of complex life, represented by trilobites. Second Contribution to the Studies on the Cambrian Faunas of North America Charles Doolittle Walcott U.S.

Stone et al. [] interpreted the white marble to be a Cambrian unit lying stratigraphically between the grey-banded Lower Bonanza King and the tan dolomitic Upper Bonanza by: For example, throughout the northeastern Mojave Desert and southern Great Basin the three lower to middle Cambrian rock formations that outcrop in the Marble Mountains (Latham Shale, Chambless Limestone and Cadiz Formation) correlate stratigraphically with the lower (oldest) three members of the very widespread Carrara Formation; quite recently.

Lower to Middle Cambrian facies of the metamor­ phosed sequence in the Wendover area differ markedly from the nearest temporally equivalent section just 60 km to the south, located near Gold Hill in the Deep Creek Mountains, Utah (McCollum and McCollum, ).Cited by: 5.

A few Middle Cambrian fossils can be found in the Cadiz Formation -- especially just below it's boundary with the cliff forming Bonanza King Dolomite. Above the Bonanza King are thin Upper Cambrian and Devonian formations, an unfossiliferous Pennsylvanian Limestone, and finally, the Permian age Bird Spring Limestone.

Middle Cambrian strata comprise the Forest Hills Formation (to replace the Fossil Brook and Porter Road formations) and Upper Cambrian strata the King Square Formation (to replace the Hastings Cove and Agnostus Cove formations) and Silver Falls Formation (to replace the Black Shale Brook and Narrows formations).

Lower Ordovician strata are Cited by: One of the more prolific producers of trilobites in the Mojave Desert-Great Basin region of eastern California is the lower to middle Cambrian Carrara Formation, a sedimentary rock deposit that has yielded more than 95 species of trilobites distributed among 38 genera.

The Middle Cambrian formations are mainly L.s The Upper Cambrian series is largely dolomitic L.S. with Trilobites Significant Events • The Cambrian Explosion • There is currently some debate concerning the rapidity of life form developments during the Cambrian Period but, regardless, it was during this time that almost all of the major life.

Boundaries and subdivisions of the Cambrian System. The lower boundary of the Cambrian System is defined at a formal global stratotype section and point (GSSP), which was ratified by the International Commission on Stratigraphy (ICS) of the International Union of Geological Sciences .The lowest few feet of the Cadiz Formation contain olenellids and are therefore Lower Cambrian, but the bulk of the formation contains trilobites of Middle Cambrian aspect.

(It should be noted that, elsewhere in the Mojave Desert, the Latham Shale, Chambless Formation, and Cadiz Formation are not considered to be separate, distinct formations.The lower Cambrian rocks consist of a conformable sequence of shallow marine, clastic and carbonate sediments which overlies cratonic Precambrian plutonic or metamorphic rocks to the south and Precambrian marine sediments to the north.
