In addition to focusing upon the objectives for scientific drilling in Yellowstone, this report summarizes in moderate detail what is known about the other large silicic caldera complexes, Long Valley and Valles. Long-range core-drilling operations and initial scientific investigations are described for four sites in the Valles caldera, New Mexico.

The plan concentrates on the period to and has six primary objectives: (1) study the origin, evolution, physical/chemical dynamics of the vapor-dominated portion of the Valles geothermal system; (2) investigate the characteristics of caldera fill.

The Valles-Toledo caldera complex is famous as the site of early research on caldera formation and for its caldera-hosted, high-temperature geothermal system.

Scientific drilling in the west half of the complex, sponsored by the Office of Basic Energy Services of the Department of Energy (DOE), is part of a long-term program to answer basic questions about caldera formation processes, silicic.

While a great deal of attention has been focused on inferring conditions within deep magma reservoirs, much of the action in terms of magmatic processes such as degassing, explosive fragmentation, an. Scientific drilling at Campi Flegrei caldera is of particular interest, because it improves the amount and the quality of data for evaluating several important pending questions, such as those.

There would have to be widespread agreement within the scientific community that compelling reasons remained to drill into the Yellowstone caldera, namely, (1) that the informa- tion to be obtained would be fundamental to gaining an improved understanding of important earth processes, (2) that this infor- mation could not be attained then or in.

A major objec- tive of deep scientific drilling into an active hydrothermal system in a silicic caldera complex is to determine how the processes enu- merated above relate to ore deposition. Concentrations of many metals in hydrothermal solutions increase with an increase in dis- solved chloride (Helgeson, ; Barnes, ; Bischoff et a.

Report: Selected Data from Continental Scientific Drilling Core Holes VC-1 and VC-2A, Valles Caldera, New Mexico Abstract This report presents geochemical and isotopic data on rocks and water and wellbore geophysical data from the Continental Scientific Drilling Program core holes VC-1 and VC-2A, Valles caldera, New Mexico.

Abstract. The magmas that erupt from volcanoes on Earth originate primarily through partial melting processes initiated in the Earth's mantle. This chapter will discuss the structure and physical properties of the Earth's upper mantle that influence magma generation, physical mechanisms leading to melting, and the chemical compositions of mantle melts.

A program of scientific drilling has been initiated at Valles, and additional scientific drilling has been proposed.

The first of the new holes would investigate the vapor cap associated with the hydrothermal system at Sulphur Springs in the southwestern part of the caldera where a hole to m deep should penetrate the steam zone and.

Geologists drilling an exploratory geothermal well in in the Krafla volcano, Iceland, encountered a problem they were unprepared for: magma which flowed into the well at kilometers depth. Scientific Drilling Project by DOSECC Core Drilling Services. The Long Valley Exploratory Well (LVEW) is situated on the resurgent dome of Long Valley Caldera, at the boundary of the Sierra Nevada and the Basin and Range Province in eastern California (Figure 1).

A coordinated onshore–offshore drilling strategy has been developed to reconstruct the structure and evolution of Campi Flegrei and to investigate volcanic precursors by examining (a) the succession of volcanic and hydrothermal products and related processes, (b) the inner structure of the caldera resurgence, (c) the physical, chemical, and.
