    Cambrian Stratigraphy, Jordan GeoArabia, , v. 19, no. 3, p. Gulf PetroLink, Bahrain Cambrian stratigraphy of Jordan John H. Powell, Abdulkader M. Abed and Yves-Michel Le Nindre ABSTRACT The lower and middle Cambrian succession (Ram Group) in Jordan is described in lexicon-style format to document an important phase of Earth history. The Middle Benue Trough The Middle Benue Trough extends Northeast ward approximately as far as line joining Bashar and Mutum Biyu. This boundary marks the Southern limit of the Gombe and Keri-Keri Formation while the older sediments of the Upper Benue Trough undergo lateral facies change in .

    This chapter reviews and synthesizes the lithostratigraphy, biostratigraphy, chronostratigraphy, and breccia types of the southwestern part of the great American carbonate bank in the southern Franklin Mountains (SFM), El Paso, Texas. Primary stratigraphic units of focus are the Lower Ordovician El Paso and Upper Ordovician Montoya Groups. STRATIGRAPHIC CORRELATION CHART FOR WESTERN COLORADO AND NORTHWESTERN NEW MEXICO M. E. MacLACHLAN U.S. Geological Survey Denver, Colorado INTRODUCTION The stratigraphic nomenclature applied in various parts of west-ern Colorado, northwestern New Mexico, and a small part of east- central Utah is summarized in the accompanying chart (fig. 1).

    Other articles where Cambrian Series 3 Series is discussed: Cambrian Period: to million years ago), Series 3 ( million to million years ago), and the Furongian Series ( million to million years ago). Cambrian: Stratigraphy. A lot can happen in 40 million years, the approximate length of the Cambrian period. Animals showed dramatic diversification during this period of Earth's history. This has been called the "Cambrian Explosion". When the fossil record is scrutinized closely.

Schematic restored stratigraphic cross section, main ranges of the Rocky Mountains east to the plains, showing the Cambrian and Ordovician rocks of the Bow River–Kicking Horse transect (modified from Aitken,his figure 4, used with permission of the Bulletin of Canadian Petroleum Geology).The Kicking Horse rim was the locus of the facies changes in the Southern Rocky Mountains.

book Cambrian, late Late. The southern Canadian Rocky Mountains feature excellent exposures of Lower to Middle Cambrian stratigraphy in a series of imbricated thrust sheets. This two-day field excursion, a round trip of km by highway, examines the Lower to Middle Cambrian sequence in a series of six stops that culminate with a hike to the famous Middle Cambrian.

The Cathedral Formation is a stratigraphic unit in the southern Canadian Rockies of Alberta and British Columbia, on the western edge of the Western Canada Sedimentary is a thick sequence of carbonate rocks of Middle Cambrian age.

It was named for Cathedral Mountain in Yoho National Park by Charles Doolittle Walcott, the discoverer of the Burgess shale y: Canada. The Stratigraphy of the Cambrian period currently has several schemes used for ordering geologic formations from the period. The International Commission on Stratigraphy−ICS scheme has set a stratotype section for the base of the Cambrian, dated quite accurately to ± million years ago.

Russian and Chinese scientists have developed a different scheme. Stratigraphy of the Middle Cambrian platformal succession, southern Rocky Mountains.

The Middle Cambrian Spence Shale Member contains meter-scale, shallowing-up cycles (parasequences) and record approximately ky of deposition.

These meter-scale cycles are nested within transgressive systems tracts (TST) and highstand systems tracts (HST) which reflect different stages of a lower-order, higher-magnitude sea-level : Scott H. Wright. The primary objectives of the ISCS are to define the series and stages of the Cambrian by means of the internationally agreed rules of the ICS and to provide the international forum for scientific discussions and interchange on all aspects of the Cambrian.

The Continental Dynamics - Rocky Mountains (CD-ROM) experiment is the study of the geodynamic processes that created the southwestern United States.
