Common to elevations ranging from 3040 to 2740 m in the region, the mixed conifer stand, within the entirety of the tower footprint in all directions, provides an excellent setting for studying the seasonal interaction between snow and vegetation. Site Description - The Valles Caldera Mixed Conifer site is located in the 1200 km2 Jemez River basin in north-central New Mexico. This is the AmeriFlux version of the carbon flux data for the site US-Vcm Valles Caldera Mixed Conifer. The Sulphur Springs subsystem is not as wellĪmeriFlux US-Vcm Valles Caldera Mixed Conifer The Redondo Creek subsystem has been more extensively studied than other parts of the system. Faults and related fractures control the flow of thermal fluids in the subsystem, which is bounded by high-angle faults. Most of the permeability is in the high-angle, normal faults and associated fractures that form the Redondo Creek Graben. The permeability in the Redondo Creek subsystem is controlled by stratigraphy and fault-related structures. Two subsystems are generally recognized within the larger geothermal system: the Redondo Creek subsystem and the Sulphur Creek subsystem. A vapor zone containing steam, carbon dioxide, and other gases exists above parts of the liquid-dominated geothermal zone. The heated geothermal water rises convectively to depths of 2,000 feet or less and mixes with other ground water as it flows away from the geothermal reservoir. The geothermal reservoir is recharged by meteorically derived water that moves downward from the aquifers in the caldera fill to depths of 6,500 feet or more and at temperatures reaching about 330 degrees Celsius. Nonthermal ground water in Valles Caldera occurs in diverse perched aquifers and deeper valley-fill aquifers. The principal reservoir of geothermal fluids is at depth under the central and western parts of the caldera. Two types of near-surface thermal water are in the caldera: thermal meteoric water and acid sulfate water. Several distinct types of thermal and nonthermal ground water are recognized in the Jemez Mountains. Geological Survey study of the area in light of more recent information. This report describes the geothermal hydrology of the Jemez Mountains and presents results of an earlier 1972-75 U.S. The mountains contain the Valles geothermal system, which was investigated during 1970-82 as a source of geothermal energy. The Jemez Mountains in north-central New Mexico are volcanic in origin and have a large central caldera known as Valles Caldera.
Geothermal hydrology of Valles Caldera and the southwestern Jemez Mountains, New Mexico Its vegetation is composed of a Ponderosa Pine (Pinus Ponderosa) overstory and a Gambel Oak (Quercus gambelii) understory.
The Ponderosa Pine forest is the warmest and lowest (below 2700m) zone of the forests in the Valles Caldera National Preserve.
Site Description - The Valles Caldera Ponderosa Pine site is located in the 1200km2 Jemez River basin of the Jemez Mountains in north-central New Mexico at the southern margin of the Rocky Mountain ecoregion. This is the AmeriFlux version of the carbon flux data for the site US-Vcp Valles Caldera Ponderosa Pine. Some waters display chemical and isotopic characteristics intermediate between the types listed.more » The object of the data is to help interpret geothermal potential of the Jemez Mountains region and to provide background data for investigating problems in hydrology, structural geology, hydrothermal alterations, and hydrothermal solution chemistry.« lessĪmeriFlux US-Vcp Valles Caldera Ponderosa Pine Waters of the region can be categorized into five general types: (1) surface and near surface meteoric waters (2) acid-sulfate waters ( Valles Caldera) (3) thermal meteoric waters ( Valles Caldera) (4) deep geothermal and derivative waters ( Valles Caldera) and (5) mineralized waters near San Ysidro. This region includes all thermal and mineral waters associated with Valles Caldera and many of those located near the Nacimiento Uplift, near San Ysidro. Counce, D.įield, chemical, and isotopic data for 95 thermal and nonthermal waters of the southern Jemez Mountains, New Mexico are presented.
