Depositional systems in the Rinconada Formation (Precambrian), Taos County, New Mexico
— Michael E. Barrett and C. E. Kirschner

The Rinconada Formation is part of a metasedimentary sequence exposed in the Picuris Range south of Taos, New Mexico. It is composed of interbedded quartzite and schist, which has been metamorphosed to medium grade and undergone successive deformations. In spite of this, the quartzite units still retain many sedimentary textures, including abun- dant crossbeds, and original vertical and lateral variations in grain size. Analysis of the sedimentary features has resulted in the recognition of several depositional environments within the Rinconada.
