INTRODUCTION In 1889-90 the young energetic chairman of the Biology Department at the University of Cincinnati was facing a dilemma. He was already recognized nationally for his research in geology (about 24 papers in this area since 1877) and had, in 1885, established a scientific journal that was rapidly gaining an international reputation. However, his new line of scientific endeavor, that b...

Analogous to the field of geomorphology (a subfield of geology that deals with the structure and evolution of the surface of the earth), the new field of hydromorphology (a subfield of hydrology), deals with the structure, evolution, and dynamic morphology of hydrologic systems over time (e.g., years, decades, and centuries). The need for this new subfield of hydrology stems from the enormous s...

Loess and loess-like deposits cover large areas of Golestan province of Iran, a well-known region in the world for its high incidence rate of esophageal cancer (EC). Despite numerous published works on the possible contributing factors for the observed high incidence rate, very little attention has been given so far to a possible link between the mineralogy of loess deposits in the region and E...

The paper aims to outline the main characteristics of term ‘geological diversity’ in its three most clear and interrelated aspects: legal, worldview, natural historic. legal aspect geodiversity now seems be clearly comprehended efficient regard primary tasks. experience regulation international law various objects is considered relation concept world her-itage. Based on convention biological di...

–I developed a classification system for streams in Michigan’s Upper Peninsula (UP) using a landscape-based approach that was originally developed for Lower Peninsula (LP) Michigan streams. Multiple linear regression, cluster analysis, and graphical techniques were used to examine stream attribute data (stream size, temperature, hydrology, gradient, water chemistry, valley type, fish community,...

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...

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...
