Abstract:

Joseph Silas Diller worked as a United States Geological Survey (USGS) geologist for some forty years, from 1883 to 1923. While his principal interest was in petrography, he was responsible for production of numerous geological maps, reconnaissance surveys and economic geologic studies. A majority of these were in Southern Cascadia, the complex region of southern Oregon and northern California that encompasses portions of the eastern Great Basin, Sierra Nevada, Cascade Volcanic, Great Valley, Klamath Mountains and Coast Ranges geologic provinces. Among his achievements were the production of s

ABSTRACT The California Air Resources Board Airborne Toxic Control Measure for Construction, Grading, Quarrying, and Surface Mining Operations (ATCM) provides requirements for the evaluation for naturally occurring asbestos (NOA) on a construction site. There are two compliance triggers: (1) a determination that the site is located within a geographic ultramafic rock unit, defined as a geographic area designated as an ultramafic rock on referenced maps, and (2) the presence of NOA, serpentinite, or ultramafic rock. The California Geological Survey requires that NOA evaluations be conducted by

Few geologists today possess the mountaineering skills to study rocks exposed in the topographically challenging terrain of the Tetons. Even fewer can claim the accomplishment of making the first geologic map of an entire mountain range. One of these pioneering geologists is John C.

In addition to his field geology expertise, Dr. Reed also has a special talent for communicating complex geologic concepts to the public. The purpose of this project was to

Abstract:

When a geologist sets up a geologic model, various types of disparate information may be available, such as exposures, boreholes, and (or) geophysical data. In recent years, the amount of geophysical data available has been increasing, a trend that is only expected to continue. It is nontrivial (and often, in practice, impossible) for the geologist to take all the details of the geophysical data into account when setting up a geologic model. We have developed an approach that allows for the objective quantification of information from geophysical data and borehole observations in a way that is

Abstract:

In mineral resource estimation, identification of the geological domains to be used for modeling, and the type of boundaries dividing them, is a major concern. Generally, the variables within a domain are estimated with an assumption of the hard boundaries (sharp contact). However, in many cases, the geologic structures that generate a deposit are transitional (overlapping of several geologic domains). Consequently, boundary identification of the geological domains is essential for an accurate estimate of resources. This paper considers a real application to examine whether the addition of geo

ABSTRACT Rockfalls are one of the most common types of slope failures that affect cut slopes along roadways in mountainous regions. The Rockfall Hazard Rating System (RHRS), started in Oregon and adopted by various U.S. states, is used to rate cut slopes with respect to their likelihood of releasing rockfalls. Existing rating systems use semi-quantitative approaches to rate geological and non-geological factors. The main geologic factors are favorability/unfavorability of orientation of discontinuities with respect to the orientation of slope faces and likelihood of differential weathering lea

Abstract:

Geologic process models predict the geometry of geologic strata and their petrophysical properties, based on mathematical models of geological processes that affect the formation and evolution of geologic strata. Such processes include erosion, sediment transport, and deposition. The resulting forward model is typically nonlinear. Given observations and a misfit measure, one may attempt inversion of these models to estimate process parameters that yield compatible predictions. For seismostratigraphic inversion, seismic data are used as observations. We tested such an algorithm in a prograding-

Time is a continuum and is real, according to Peircean theory. It is also the constitutive category of geology that is equivalent to the Peircean category of Thirdness. As a continuum, time was created and evolved. Although the conceptions of a linear and a cyclic time played a role in the development of geological science, they were not deduced from geological observations; they were a priori assumptions. Hence, time is a methodological device. Continuity, for Peirce, exists on evolutionary terms. Chance or Firstness is always present in every phenomenon. So, time is continual rather then con

Some of the same functionality of these software packages can be accomplished by workflows that incorporate built-in geoprocessing tools of Geographic Information System (GIS) software.

The term anthropogeology was coined in 1959 by the Austrian geologist Heinrich Häusler. It was taken up by the Swiss geologist Heinrich Jäckli in 1972, and independently introduced again by the German geologist Rudolf Hohl in 1974. Their concept aimed at mitigating humankind’s geotechnical and ecological impact in the dimension of endogenic and exogenic geologic processes. In that context anthropogeology was defined as the scientific discipline of applied geology integrating sectors of geosciences, geography, juridical, political and economic sciences as well as sectors of engineering sciences
