Crocidolite Asbestos
Below, L to R: TEM brightfield image and darkfield image of the same asbestos fiber. These images offer complementary information about the crystalline nature of the material.

 

Below, upper: TEM lattice imaging, showing atomic planes with 0.90nm spacing.
Below, lower: TEM lattice imaging, showing atomic planes with 0.45 nm spacing.

Below: TEM diffraction imaging, which enables determination of atomic plane spacing in the crystal.

Below: X-ray EDS spectrum, showing Si, Fe, Mg, Na, lines
