This paper outlines a new program of the British Columhia Geological Surbey Branch in the field of applied surficial geology. Its oh.jectivcs are to develop methodologies whereby informatiw from about 2000 existing surficial geology maps, in conjunction with subsurface data, can he used to produce derivative products in applied fields such as aggre@xte resource\. neological hazards, waste dispo...
Forward modeling of reflection seismic data is a computational process through which a geologic model (units: horizontal distance, vertical depth; layer acoustic impedance) of the subsurface is transformed into a synthetic reflection seismic record (units: horizontal distance, 2-way travel time; reflection amplitude). Synthetic seismic records (synthetics) are often generated both before and af...
Boundaries between the various topographic, geologic, and socio-political entities that span the Earth’s continental surfaces are determined by a myriad of complexly interrelated natural and/or cultural factors. Areas of large river basins, of lithologic units on geologic maps, and of nations exhibit size frequency distributions that are closely approximated by density functions in which diamet...
Paleogeographic maps represent the ultimate synthesis of complex and extensive geologic data express pictorially hypothetical landscape some region during a given time-slice deep time. Such maps, presented as paired paleogeographic paleotectonic reconstructions, have been developed to portray history greater Arctic over past 400 million years. Collectively they depict four major episodes in dev...
A geologic map is a 2-dimensional representation of an interpretation of 3-D phenomena. The work of a geologist consists mainly in (i) inferring subsurface structures from observed surface phenomena and (ii) building abductive models of events and processes that shaped them during the geologic past. In order to do this, chains of explanations are used to reconstruct the Earth history step-by-st...
Ecological community assembly is governed by a combination of (i) selection resulting from among-taxa differences in performance; (ii) dispersal resulting from organismal movement; and (iii) ecological drift resulting from stochastic changes in population sizes. The relative importance and nature of these processes can vary across environments. Selection can be homogeneous or variable, and whil...
Sentinel-2A MSI is the Landsat-like spatial resolution (10–60 m) super-spectral instrument of the European Space Agency (ESA), aimed at additional data continuity for global land surface monitoring with Landsat and Satellite Pour l’Observation de la Terre (SPOT) missions. Several simulation studies have been conducted in the last several years to show the potential of Sentinel-2A MSI (MultiSpec...
The map area includes the Big Bald Mountain Quadrangle and the western part of Tognini Spring Quadrangle. It is located south of Overland Pass in the southern Ruby Mountains and the southern Maverick Springs Range, about 60 miles (100 km) south-southeast of Elko, Nevada, and about 50 miles (80 km) northwest of Ely, Nevada (figs. 1A, B). The map area, herein referred to as the Bald Mountain area...
