Geologic maps are, by their very nature, interpretive documents. In contrast, images prepared from AVIRIS data can be used as uninterpreted, and thus unbiased, geologic maps. We are having significant success applying .AVIRIS data in this non-quantitative manner to geologic problems. Much of our success has come from the power of the Qnked windows Lrteractive Data ~stem. L,inkWinds is a visual ...

Synopsis: The Moon is the best and most accessible place to explore the origin and evolution of the entire Solar System, including the earliest evolutionary phase of our own planet, Earth, a period of time that has since been erased from the surface of the Earth. The Apollo program taught us that the dominant geologic process affecting the surfaces of planets is impact cratering. It has the cap...

The magmatic-hydrothermal system at Yellowstone National Park is unique among presently active systems in regard to its unparalleled geysers, tectonic environment, and magnitude of caldera-forming volcanic activity. However, over geologic time, systems like Yellowstone have been common and appear to have been responsible for the formation of many important basc-metal and precious-mctal ore depo...

Abstract Pyroclastic density currents are hazardous, ground-hugging, hot mixtures of gas and solid particles produced by volcanoes. Currents generated the largest explosive eruptions have traveled distances on order 100 km, their devastating impact has repeatedly marked Earth's geologic history. We show that pyroclastic from super-eruptions during Oligocene in Great Basin United States had exce...

Communication in geology is characterized by very many expressions, used in texts and lectures. Among these, nonverbal terms are much more important than in other sciences. Informations rarely reflect pure facts, rather they are expressions and results of a complex process of knowledge formation. In a geologic map for example, the structure of symbols illustrates the process of knowledge transf...

The Bahama Banks represent an environment of carbonate sedimentation widespread in the past but extremely rare today. Its occurrence presents the geologist with the opportunity of learning firsthand about geologic processes once prevalent on the earth's surface, but he has been slow to take advantage of the opportunity and slower to use the Bahama story in the classroom. Some literature on the ...

Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national s...

The vadose zone beneath the USDOE’s Hanford Site in southeastern Washington State (Fig. 1) received approximately 1 trillion liters (450 billion gallons) of liquid waste, some contaminated with radioactive and hazardous contaminants. Today, Hanford is engaged in the world’s largest environmentalcleanup project, and a variety of conceptual and mathematical vadose zone models have been developed ...
