Deposits drift residues

A general term for the entire layer or mantle of fragmental and loose, incoherent, or unconsolidated rock material, of whatever origin (residual or transported) and of a much varied character, that nearly everywhere forms the surface of the land and overlies or covers the more coherent bedrock. It includes rock debris (weathered in place) of all kinds, volcanic ash, glacial drift, alluvium, loess and aeolian deposits, vegetal accumulations, and soils. 

Molecular and structural characteristics of methoxysilane SA-layers deposited on inorganic subtrates can be obtained using DRIFT spectroscopy in combination with TOF-SIMS. The hydrolysis rates are strongly influenced by the acid/base properties of the oxide surface. In accord to this, the contribution of residual Si-OCHs units is much lower for SA-layers on the basic alumina. The outmost layers of the polysiloxanes consist of completely hydrolyzed species. In case of methylsilanes, the SIMS spectra indicate the presence of T and T OH silsesquioxanes whereas for higher alkylsilanes the formation of T OH isomers is likely. This hypothesis has to be addressed in future studies with particular focus on structural aspects. 

The atmosphere represents an important environmental compartment for receiving and distributing residues of organic chemicals. Pesticides, for example, may enter the atmosphere during application to soil, crops, and forests by the process of drift and by volatilization of residual deposits after application... 

During the Pleistocene, McMurdo Sound was filled with the ice of the grounded Ross Ice Shelf. The Ross-Sea drift that was deposited by this ice is largely unweathered, is underlain by residual bodies of ice, and is bounded by terminal moraines (Stuiver et al. 1981). These deposits occur primarily along the western coast of McMurdo Sound including the Brown...
