Thin section
Thin section polarized-light microscopy is a simple, cost-effective and nondestructive technique utilized to delineate crystalline or amorphous solids at varying scales and spatial resolutions; thereby allowing the different phases to be studied within their textural framework. Estimates of chemical composition and insight into the solid’s genesis can be deduced via unique textural characterist...
متن کاملPermeability in the thin section
Numerical experimentation is an attractive complement to physical measurement of rock properties. In such experiments, a physical process is simulated in a pore space and then the corresponding property is calculated. For example, a simulation of viscous fluid flow through pores provides permeability. Many authors have used pore-scale numerical methods, such as Lattice-Boltzmann and network mod...
متن کاملShock Compression of Feldspars
Hugoniot data for oligoclase and microcline to 670 and 580 kb and release adiabat data for oligoclase were obtained by means of the inclined mirror and immersed-foil-reflected-light techniques, respectively. Oligoclase and microcline have Hugoniot elastic limits in the range of 40-55 and 80-85 kb. These limits increase slightly with increasing driving shock pressure. Above the elastic limit, ex...
متن کاملMantled feldspars and synneusis
Synneusis, the drifting together and systematic attachment of crystals in a melt, is involved in three of the known origins for mantled feldspars: (1) overgrowth, (2) exsolution, and (3) filling of skeletal plagioclase. Quartz latite dikes of the Chocolate Mountains, California, contain plagioclase crystals in parallel and twinned synneusis. Sanidine mantles consisting of segments, each crystal...
متن کاملHow Thin Should a Section Be?
In considering the electron microscopic study of sections of tissue as a practical approach to the study of cell structure, the cytologist is faced with a number of possible decisions with respect to the way in which he will prepare his material. Not the least of these is the problem of how thin the section of tissue should be to serve his purpose. A useful section of a sample must satisfy the ...
