Red Hill volcanic field

Red Hill-Quemado

火山原 · United States · 2300m

The Red Hill-Quemado Volcanic Field in New Mexico, USA, contains more than 40 scoria cones, some of which are in the area shown in this August 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 34 km across). There are also phreatomagmatic features including the 2-km-wide Zuni Salt Lake maar at the top of this Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 69 km across).

地質学的概要

The Red Hill-Quemado volcanic field in western New Mexico is across the border from the Springerville volcanic field in Arizona and contains more than 40 cinder cones and maars that were active from the late Miocene to early Holocene. The volcanic field lies along the NE-trending Jemez Lineament that extends from SE Colorado to east-central Arizona. Dating by Onken and Forman (2017) showed that three eruptive events took place during the early Holocene, and that the 2-km-wide Zuni Salt Lake maar with its late-stage nested cinder cones was formed about 11,000-11,800 calibrated 14C years ago.

Wikipedia の要約

英語版の要約

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 24 kilometers (15 mi) east of the larger Springerville volcanic field and includes Zuñi Salt Lake. The area is made up of scoria cone and silicic dome fields. Over 40 volcanic vents have been identified in the field. These erupted basaltic flows, with no other rock types evident in the field.
