Kinney Quarry, Manzanita Mountains, unit 4 (Carboniferous of the United States)

Where: Bernalillo County, New Mexico (34.9° N, 106.3° W: paleocoordinates 0.4° S, 36.9° W)

• coordinate estimated from map

When: Pine Shadow Member (Wild Cow Formation), Virgilian (303.7 - 298.9 Ma)

• Wild Cow Formation, which is composed of rhythmic sequences of arkosic sandstone, gray, tan, and red shale, and gray marine limestone of Missourian to earliest Wolfcamian age. Myers (1973, 1988) recognized three members of the Wild Cow, in ascending order Sol de Mete, Pine Shadow, and La Casa. About 28 m of the Pine Shadow Member (lower Virgilian) are exposed in the Kinney Quarry... the member consiste generally of gray marine limstones alternating with marine or nonmarine shale, sandstone, and conglomerate. Lateral facies changes within the Pine Shadow Member are pronounced...early Virgilian age is based on studies of fusulinids.

Environment/lithology: lagoonal or restricted shallow subtidal; shale

• deposition in conditions of lowered salinity; deposition occurred in quiet, possibly oxygen-poor waters with restricted circulation; conection with normal marine environments persisted; mud-crack structures are observed

•#75170: anoxic, very low-energy depositional environment; waters of greatly reduced salinity; deep lagoon or bay; laminations may represent minimal tidal influence

•ref #75238: ostracods are characteristic of a mixed mear-shore -marine and brackish-water fauna that appears to have become less marine above the basal limestone

• Thickness: 0.2 m

•Fig. 5: shale, olive gray (5 Y 4/1); weathers dark yellowish brown (10 YR 4/2); plastic; very calcareous; highly fossiliferous; part of main fish-plant interval

•text: units 3 and 4 are gray to olive-gray, orange- to brown-weathering shales totaling 30-40 cm in thickness. Lithological variation within this interval is pronounced. Typically it is finely laminar, relatively compact, and slightly to moderately calcareous, but locally becomes soft and highly fissile, especially in weathered exposures.

•ref #75170: indurated, calcareous shale

•ref #75181: laminated (1-10 mm, dark) to thinly bedded, shale; polygonal (2-20 cm) structures smilar to mud-cracks

Size classes: macrofossils, mesofossils

• Nearly all of the published fossils from the Kinney Quarry have been collected from units 3 and 4.
