Many landfill siting reports, of which those of the Franklin County, OH, landfill are typical, imply continuity of minor sand bodies in till between widely-spaced test holes where sand deposits fall within similar depth ranges. This review of studies of the local origin of most sand and gravel "lenses" or "seams," and their transport in active glaciers, however, indicate that most such deposits...

Mineral dust aerosols cool Earth directly by scattering incoming solar radiation and indirectly by affecting clouds and biogeochemical cycles. Recent Earth history has featured quasi-100,000-y, glacial-interglacial climate cycles with lower/higher temperatures and greenhouse gas concentrations during glacials/interglacials. Global average, glacial maxima dust levels were more than 3 times highe...

Arctic Region (AR); Its role in global climate change, recently opened commercial sea routes, unexploited industrial resources, unique polar ecosystem and international geopolitical balance making it a strategic area that attracts the attention of many countries. In this aspect, Council carries out various studies cooperation, especially interdisciplinary scientific research AR. Apart from Coun...

The rate of sediment supply from erosional catchment to depositional basin depends primarily upon climate, relief, catchment slope and lithology. It varies in both time and space. Spatial changes in erosion rates due to variations in lithology are illustrated by contrasting rates of drainage divide migration away from faults of known ages. Time variations in relative sediment supply are extreme...

In the second revised edition of this widely used textbook, practical aspects are given particular emphasis. Two new chapters have been added-one on geology in engineering, another summarizing the subject matter of physical geology and explaining its relation to earth history. The chapter on geology in engineering, and those on minerals and mineral deposits, offer especially good material for a...
