...Ralf Milke Abstract For centuries blotting sand has been used for drying ink on manuscripts, but very little is known about the nature of such sands. In this study, 165 blotting sand samples used from the 14th – 19th century in SW-Germany and northern Switzerland are analysed by petrographic...

... of the sediment layer is sensitive to the profile of sediment properties, frequency, and wave amplitude. The dynamic behavior of coarse sand and porous rocks excited by acoustic waves and earthquakes should be modeled by the Blot porous-solid model in which the fast compressional waves, the slow compressional...

... deposits in which the ground water table originates at certain depths below the surface. The model is formulated using Biot's classicalsmall strain theory for porous fluid-saturated media which has been reported in several papers (Biot, 1941-1962). Literature search reveals that Blot's two-phased linear...

...W. T. Thom © 1928 American Association of Petroleum Geologists. All rights reserved 1928 American Association of Petroleum Geologists It is a matter of common knowledge that in some regions buried sands are either dry or are only partially saturated with water, and that, in consequence...

... with a derivation of the field equations in cylindrical coordinates on the basis of Blot's linear theory for porous, fluid-saturated media. The field equations are then reduced to Helmoholtz-type equations with the aid of four scalar potentials related to the solid and fluid constituents of the two-phased medium...

... marine fishes, plants and soft-bodied invertebrates. It is joined by Monte Postale, located nearby and also famous for marine fishes and plants. These two localities are the source of most fossils from the Bolca area in museums, and have yielded over 100 000 exceptionally preserved fossils (e.g. Blot...

...Gerald M. Mavko; Ed Harp Abstract Acceleration and wave-induced pore pressure were recorded in a saturated sand during the 1980 Mammoth Lakes, California, earthquake sequence. For the largest event recorded, the pore pressure was observed to be proportional to vertical surface acceleration during...

... March and June 1995. D. biperforata is disc-shaped, with a test made up of organic matter, reinforced with sand grains. The species exhibits different test morphologies, the most abundant type being the biperforate which has two holes, or lunules, through its test. A less common type is the non-lunulate...

... outweighed by the advantages. The finest rock flour which is an undesirable artificial product is eliminated and with care the generally coarser clay particles and finest sand are preserved. The washing is done in a large test tube which is repeatedly filled with water and inverted until the particles...

... deposited as compared with the periods of water influx from the east in relation to the amount of organic matter and sand deposited. Somewhat the same explanation may well apply to other clay seams not identifiable as marine. It would account for lack of noticeable oil content in the shales and the clay...

.... When the gas cap was incised by the Clearwater River (probably in pre-Pleistocene time) the gas escaped into the atmosphere leaving the unimpregnated clean white sands which were formerly occupied by the gas cap. The heavy asphaltic oil was unable to escape and “blotted” its way selectively...

...Ashvin Wickramasooriya; Udaya Gunawardane Abstract Pulmoddai mineral sand deposit which extends about 800,000m 2 is located in the Northeast coastal zone of Sri Lanka. It is the largest and well known heavy mineral sand deposit in Sri Lanka. High-quality Zirconium-bearing minerals like Rutile...

... in a reservoir characterization program, especially when attenuation is well understood at the borehole. To support this claim, we present attenuation profiles of fluid saturated rocks from four sites: (1) Siberia Ridge Field, a fractured tight gas-sand reservoir in Wyoming; (2) Buena Vista Hills, a low...

... price. The open-bond theory of the bleaching action of active oil sands and bleaching clays by selective adsorption set forth by the writer in previous papers 3 , 4 , 5 , 6 , 7 , 8 has met every test that has thus far been devised. Clay particles (or oil sand grains) are potential bleaching...

... then on, the focus was shared between family and science, and life became rather hectic and sleep-deprived. The thesis was submitted hours before the deadline, under strong time pressure. My master’s project was literally made in a sand box. This box of marine sand, set up at Aarhus University’s field station...

... of sedimentation, in the area as a whole, seemingly ends with its indefinite products, those alternating beds of gravel, sand, silt, and clay with their varying amounts of associated organic matter, and it is futile to assign to them definite time or structural limits. A study of the geology of the recent...

The paper is illustrated by many photographs of cross sections and vertical views of the deformed material, showing a variety of faulted structures. All of the tangential...

.... The highway pavement is made of three shallow asphalt layers laid on a mixture of lime, cement, sand, and gravel-size debris in contact with the underlying soil. The pavement and subgrade stratigraphy were calibrated by trial holes. The average dielectric constant of the asphalt (8.0) is comparable...
