ELECTRON MICROSCOPY AND MICROANALYSIS
The laboratory has an electron microscope-microanalyzer MV 2300, CamScan (Great Britain). The installation makes it possible to:
-
get images of paleontological and mineralogical objects in secondary-scattered electrons with a magnification from n×10 to n×104 times with a maximum resolution of » 50 NM;
-
perform elemental analysis of minerals for chemical elements from boron to uranium with lower limits of determination of about 0.1% wt;
-
study the distribution of chemical elements in targeted surface areas of samples or along a given direction;
-
observe the integral cathodoluminescence of minerals (diamonds, zircons and others) using a special attachment;
-
using a back-scattered electron detector, get distribution maps of various phases (minerals, ore concentrates, alloys, etc.) in the Zef range from 6 to 90 with a resolution of up to 0.1 Z;
-
obtain quantitative characteristics of images (secondary-scattered electrons, back-scattered electrons, in cathodoluminescence): phase perimeters, phase areas, sizes of some individuals.
For analysis it is possible to use individual grains, combined thin sections, polished rock chip samples.
