i am delighted to announce completion of the second issue of the new journal of “geopersia”, a product of the new era of replacing the persian language journals with specific english-language ones. our purpose is to provide a journal that offers a multi-disciplinary analysis of issues concerning geology subjects (i.e. sedimentology, stratigraphy, paleontology, petroleum geology, engineering geo...

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...

As magmas rise toward the surface, they traverse regions of the mantle and crust with which they are not in equilibrium; to the extent that time and the intimacy of their physical contact permit, the melts and country rocks will interact chemically. We have modeled aspects of these chemical interactions in terms of ion-exchange processes similar to those operating in simple chromatographic colu...

Geology is a complex, semantically rich domain involving the interpretation of geological maps as external visualizations. Geological maps are complex in particular because 3dimensional features must be inferred from 2-dimensional representations depicted by differing line types and weights. Modeling building, as an internal mental activity, is also required in order to achieve deep understandi...

The standard account of the reasoning process within geology views it as lacking a distinctive methodology of its own. Rather, geology is described as a derivative science, relying on the logical techniques exemplified by physics. I argue that this account is inadequate and skews our understanding of both geology and the scientific process in general. Far from simply taking up and applying the ...

Modem geology was founded by James Hutton at the end of the 18th cenhuy as an observational, descriptive, qualitative, and subjective science. It was the pioneer work of Pearson (1901) and Spearman (1904) in statistics applied to agriculture, biology, medicine, and psychology, that led to the first major inroads of quantitative techniques in geology and the models they used were above all stati...
