Today, colour or multichannel satellite and aerial images are increasingly becoming available due to the commercial availability of multispectral digital sensors and pansharpening function of the co...
Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology...
A novel polysiloxane (PSA-PFMS) fabric finishing agent, bearing pendant stearyl acrylate, polyether, epoxy and trifluoropropyl side groups, etc., was synthesized by hydrosilylation of polytrifluoropro...
The morphology of pore space has a strong effect on mechanical and transport properties of mudrocks and clay-rich fault gouge, but its characterization has been mostly indirect. We report on a study o...
As many hybodont sharks are known solely from their teeth, this investigation approaches the phylogeny of the group with an emphasis on tooth morphology and dentitional patterns. The preliminary resul...
Bed surface particle size patchiness may play a central role in bedload and morphologic re-sponse to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of be...
Abstract: Hisingerite, first described in 1810, has been variously regarded as noncrystalline, as a septechlorite, as ferric allophane, as ferric halloysite and as poorly crystalline nontronite. Hisin...
Abstract: Redox and acid-base reactions play important roles in the fate of metal contaminants in soils and sediments. The presence of significant amounts of Cr, Pb and other toxic heavy metals in con...
Morphologiesofprimary rhyolitic meltinclusions in three successive populations of quartz phenocrysts in asinglevolcanic unit illustrate the changeofinclusion shape after trapping. The 14MaBadlandslava...
Hydrothermal alteration has caused illitization along a 40m vertical profile in the Tsantilis bentonite deposit, Eastern Milos, Greece which consists principally of a Wyoming-type montmorillonite and ...
Scanning electron microscopy has revealed the presence of spherical, lath and platy kaolinite in gels with Si/Al atomic ratio ranging from 1.84 to 0.76 that are hydrothermally treated under different ...
Smectite was reacted at several temperatures between 200°C and 500°C to produce interstratified illite/smectite (I/S) with different proportions of expandable layers. Dispersed and sedimented products...
This paper aims at characterizing the morphology, texture, and microstructure of three hydrated kaolin rich clays (f < 0.2 &micro;m) from volcanic soils. These clays represent a weathering sequence in...
Abstract: Many of the presently oxidized Georgia kaolins probably existed originally in the reduced (gray) state. For that reason, the distribution of iron sulfides in presently gray kaolins may eluci...
