The stratigraphic units of primary interest for vadose zone flow are the Bandelier Tuff, Cerros del Rio basalt, and Puye Formation; see Color Plate 2.

      Indeed, they have been mistaken for lizards. They are enclosed by a low wall of unshaped stones. This shrine is on the Potrero de las Vacas, one of the long, high, narrow mesas of the Pajarito Plateau, in the rough, little-travelled southern portion of Bandelier National Monument, west of . Pajarito fault zone extends at least 1, m (5, ft) to the east of the main Pajarito fault escarpment. Stratigraphic units in the study area include upper units of the Tshirege Member of the early Pleistocene Bandelier Tuff, early Pleistocene alluvial fan deposits that predate.

    that Bandelier expressed in his diary. Despite the extraordinary wealth of archaeologi-cal sites on the Pajarito Plateau—the volcanic tuff tableland dissected by Frijoles and other canyons— relatively little archaeology has been done there. Because of this, the story of Bandelier National Monument and the surrounding plateau has. On the western part of the Pajarito Plateau, the Bandelier Tuff overlaps onto the Tschicoma Formation, which consists of older dacitic volcanics that form the Jemez Mountains. The tuff is underlain by the fanglomerate of the Puye Formation in the central plateau. Near the Rio Grande, the Bandelier Tuff is underlain by the Cerros del Rio basalts.

These refinements are necessary because the internal stratigraphy of the Bandelier Tuff varies with distance from its caldera sources.

The Bandelier Tuff makes up a significant portion of the vadose zone on the Pajarito Plateau, which is located on the flanks of the Valles Caldera in north-central New Mexico.

The southern Pajarito fault zone has over ft ( m) of pre-Bandelier Tuff down-to-the-east movement. The Pajarito fault zone and a major pre-Bandelier Tuff fault identified herein may constitute the local boundaries of the southern continuation of the intra-rift Velarde graben.

The town site of Los Alamos, Los Alamos National Laboratory, and portions of White Rock are built on the Tshirege Tuff.

Full text of "Pajarito Plateau. The Pajarito Plateau is primarily composed of ignimbrite, a voluminous deposit of volcanic tuff laid down in an explosive eruption — in this case, a pair of eruptions from the nearby Valles Caldera.

The two ignimbrite-forming eruptions occurred about million and million years ago and ejected about cubic kilometers of rock each. The orange-pink rock formations constituting the resulting ignimbrites. Edgar Lee Hewett, founder of the Museum of New Mexico and a fervent Southwest booster at the turn of the last century, was a pioneer archaeologist on New Mexico's Pajarito Plateau -- in fact, he named the place, which is largely the property of the Los Alamos National Laboratory since the days of the Manhattan Project.4/5(1).

East of the Valles caldera, on the Pajarito Plateau, the Bandelier Tuff cooling unit stratigraphy has been mapped in detail and correlated with geochemical data (e.g., Broxton and Reneau, ; Goff, ).

Beyond the Pajarito Plateau, it is challenging to map the Bandelier Tuff based on cooling unit stratigraphy alone because welding and vapor-phase alteration vary greatly with radial distance from the Valles Cited by: 4.
