An easy identification chart for major rock-forming minerals by polarizing microscope.

Ore Minerals under the Microscope

THE student of geology in the course of his training usually passes through three stages of achievement: A first in which he learns to identify the materials with which he works; a second in which he learns to recognize the distribution of these materials in space; and a third in which, from this distribution, he interprets the geologic history of the area of the assemblage of materials. Paraph...

Identification of Magnetic Minerals by Scanning Electron Microscope and Application of Ferrofluid

Magnetic minerals are mostly identified by a combination of rock magnetic and microscopic techniques and the ferrofluid method in combination with an optical microscope was applied during the last decades. But today, scanning electron microscopy (SEM) is preferred for the observation of mineral phases because its depth of focus and resolving capability at the same magnification. In this study, ...

Wettability of Common Rock-forming Minerals in a Co2-brine System at Reservoir Conditions

Wettability plays a major role in subsurface fluid migration, however little empirical evidence besides qualitative relative permeability data in this context is known about the characteristics of carbon dioxide (CO2). Core analysts use several methods combined for use in the oil industry, including the USBM (U.S. Bureau of Mines) method and Amott test, supported visually by images from an envi...

Persulfate Activation by Major Soil Minerals

by MUSHTAQUE AHMAD, M.S. Washington State University December 2008 Chair: Richard J. Watts Oxidant interaction with subsurface materials is a major factor influencing the effective application of in situ chemical oxidation (ISCO) for contaminant destruction. The newest and least explored ISCO oxidant source is persulfate. Persulfate interaction with subsurface minerals was investigated as a bas...
