Summary:

Bisbee Group subdivided (ascending) into Glance Conglomerate, Morita Formation, Mural Limestone, and Cintura Formation; recognized in Mule and Huachuca Mountains of Pedregosa basin. Bisbee Group (undivided) recognized in Pedregosa, Chiricahua, and Dos Cabezas Mountains of Pedregosa basin. Bisbee Group divided into Glance Conglomerate, and undivided Morita and Cintura Formations; recognized in Little Dragoon Mountains and nearby areas of Pedregosa basin. Bisbee Group divided into McGhee Peak Formation of Gillerman (1958), Carbonate Hill Limestone of Gillerman, and Still Ridge Formation of Gillerman; recognized in central Peloncillo Mountains of Pedregosa basin. Bisbee Group divided into Glance Conglomerate, Willow Canyon Formation, Apache Canyon Formation, Shellenberger Canyon Formation, and Turney Ranch Formation; recognized in Santa Rita, Empire, and Whetstone Mountains of Basin-and-Range province. Called Bisbee Formation in Dragoon Mountains and Tombstone area of Pedregosa basin and in the Patagonia Mountains of the Basin-and-Range province, where it replaces Molly Gibson Formation of Stoyanow (1949). Term Bisbee Group not used locally in Little Hatchet Mountains of Pedregosa basin and Basin-and-Range province. Rocks assignable to Bisbee have not been recognized north of Steele Hills, Cochise Co, AZ in Basin-and-Range province. [See fig. 5 for regional correlations.] Is of Early Cretaceous age.

Summary:

Extended as formation to west side of Sierrita Mountains. [Inasmuch as Cooper (1971) used the term Angelica Arkose for a presumed Bisbee equivalent on the east side of the Sierrita Mountains (closer to the type Bisbee), it seems inappropriate to use Bisbee on the west side of the range even if the rocks in question look more like the Bisbee than the rocks designated as Angelica--unless compelling reasons are given for the decision to do so--and they are not on this map.] Formation rather than group used in central Chiricahua Mountains, Pima Co, AZ in the Pedregosa basin. Is of Early Cretaceous age.

Summary:

[Correlation of Morita, Mural, and Cintura to this area from the type area of these formations in the Mule Mountains seems tenuous.

Summary:

Shown on correlation chart as Bisbee Group and as Bisbee Formation in both Pedregosa basin and Basin-and-Range province (plate 1). Formation elevated to group where mapped in Swisshelm (fig. 8) and Perilla Mountains (fig. 12). Elevated to group in Dragoon Mountains where Glance Conglomerate at base is overlain by undivided Morita and Cintura Formations. [In this latter case it might have been better to have retained usage of Gilluly (1956), i.e., Bisbee Formation with Glance Conglomerate Member rather than use of Bisbee Group as used by Cooper and Silver (1964) in the Little Dragoon Mountains area.] Is of Early Cretaceous age.

Summary:

Name not used, but three formations of group (Morita Formation, Mural Limestone, and Cintura Formation) separately mapped, thus automatically elevating Bisbee (previously mapped by Cooper (1959) as a formation) to group rank in Hidalgo Co, NM in the Pedregosa basin area. Is of Early Cretaceous age.

Summary:

Age of Glance Conglomerate, basal formation of Bisbee Group, changed from Early Cretaceous to Late Jurassic and Early Cretaceous. Age of lower part of Glance is better known than the upper part. Ages of 147 +/-6 Ma (K-Ar on biotite) and 149 +/-11 Ma (Rb/Sr whole rock) determined on volcanic rocks in lower part in Lone Mountain area. Age of 151 +/-2 Ma (Rb/Sr whole rock) for rocks in lower part in northern Canelo Hills. Basal part considered to be about 150 Ma or Late Jurassic. Age of upper part of Glance is uncertain. Invertebrate fauna of Aptian-Albian age found in Mural Limestone in upper part of Bisbee. Upper part of Glance could be as old as Late Jurassic or as young as late Early Cretaceous. Geologic maps. Correlation chart. Bisbee Group shown as ranging from Late Jurassic (c. 150 Ma) into Early Cretaceous (c. 115 Ma).

Summary:

Bisbee Group. Includes (descending) Cintura Formation, Mural Limestone, Morita Formation, and Glance Conglomerate. Most of group above the Glance is medium- to dark-gray siltstone, shale, or mudstone. Beds of sandstone and, at some horizons, conglomerate or limestone make up less than 5 percent of the main part of the group. Deposited mainly in a fluvial and estuarine environment. Age is Early Cretaceous.
