The Objectives for Deep Scientific Drilling in Yellowstone National Park


Book Description

The western area of the United Stated contains three young silicic calderas, all of which contain attractive targets for scientific drilling. Of the three, the Yellowstone caldera complex is the largest, has the most intense geothermal anomalies, and is the most seismically active. On the basis of scientific objectives alone. it is easily the first choice for investigating active hydrothermal processes. This report briefly reviews what is known about the geology of Yellowstone National Park and highlights unique information that could be acquired by research drilling only in Yellowstone. However, it is not the purpose of this report to recommend specific drill sites or to put forth a specific drilling proposal. 175 refs., 9 figs., 2 tabs.













Continental Scientific Drilling Program


Book Description

The Workshop on Continental Drilling for Scientific Purposes addressed the questions of how to maximize the scientific value of current and planned continental drilling efforts of Federal agencies and industry and how to supplement these efforts with holes drilled solely for scientific purposes. The subjects treated by Workshop panels included: basement structures and deep continental basins - broad and specific questions related to understanding the earth's continental crust; thermal regimes - basic understanding of geothermal systems; mineral resources - basic understanding of ore-forming processes; earthquakes - basic understanding of earthquakes and faulting mechanisms; drilling technology - development of drilling and logging equipment capable of operating at high temperatures (up to 500 C).




Geobiology: Objectives, Concepts, Perspectives


Book Description

"Geobiology understands earth as a system, and life as part of it. In space and time, life influences earth's development, and earth's changing environments moulds life. Geobiology mirrors not only a new development in sciences, but also responses to the new challenges and demands imposed by today's world and society." --p. 1.
