Red Hill volcanic field
Template:Short description Template:Infobox mountain
Red Hill volcanic field, also known as Quemado volcanic field, is a monogenetic volcanic field located in the vicinity of the ghost town of Red Hill in Catron County New Mexico. Red Hill is Script error: No such module "convert". east of the larger Springerville volcanic field and includes Zuñi Salt Lake.[1] The area is made up of scoria cone and silicic dome fields.[2][3][4] Over 40 volcanic vents have been identified in the field.[5] These erupted basaltic flows, with no other rock types evident in the field.[6]
The largest crater in the field is Quemado crater, which is Script error: No such module "convert". across and Script error: No such module "convert". below the surrounding terrain, with a slightly elevated rim. This crater shows evidence of cycles of collapse and explosive eruption. It is surrounded by olivine basalt flows.[7]
The field is part of the Jemez Lineament, a zone of young volcanic fields stretching from central Arizona to northeastern New Mexico. Ar-Ar dating of rock from the Red Hill volcanic field reveals that it was erupted in two pulses, from 7.9-5.2 million years ago (Mya) and from 2.5 to 0.071 Mya. The older activity was along a narrow zone roughly aligned with the lineament, while later activity was across a broad north-south zone, with the focus of activity tending to move south to north. Future activity is most likely in the northern part of the field.[5]
