| contents | Permian fusulinids from Cobachi, central Sonora, Mexico Olivia Pérez Ramos Merlynd Nestell Ciencias de la Tierra Sonora Mexico Permian Cobachi fusulinids Upper Paleozoic rocks in the Cobachi area of central Sonora, Mexico, include the PicachoColorado and La Vuelta Colorada formation of Carboniferous?-Permian age. A 155 m carbonatesuccession of the Picacho Colorado Formation, exposed on the east side of Cerro Picacho Colorado,a few kilometers southeast of Cobachi, consists of pinkish and reddish limestone, cherty limestonewith some recrystallization, and bioclastic gray limestone. Crinoids, bryozoa, brachiopods and foraminifersare present indicating a marine shallow water shelf depositional environment. Well preservedfusulinaceans occur near the top of the section, but are scarce, partially silicified, and poorlypreserved in the middle part and the base of the section. Skinnerella cobachiensis n. sp., Paraskinnerellacf. P. durhami, Parafusulina P. cf. P. multisepta and three unnamed species of Parafusulinaof early Permian (Leonardian) age are described from this succession. The fusulinacean assemblagefrom this area has affinities with forms found in rocks with similar age in east central California,west Texas, southeast Mexico, and Central and South America 2002 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57219103 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.1 Vol.19 |
