troilite

For this reason, troilite is sometimes called pyrrhotite-2C.

One iron meteorite, Mundrabilla contains 25 to 35 volume percent troilite.

The troilite in this sample is used as the standard reference for sulfur isotope ratios.

There is also abundant metal and troilite.

It has been suggested that this indicates the presence of troilite (FeS).

Rose named this new mineral troilite after Troili.

In meteorites it occurs with troilite and silicate minerals.

The magnetism increases as the iron content decreases, and the troilite is non-magnetic.

It is associated with troilite, pyroxferroite, cristobalite and alkali feldspar.

Associated minerals include native iron, schreibersite, troilite and wustite.

These abundances are compared to those found in Cañon Diablo troilite.

Graphite and troilite occur in rounded nodules up to several cm in size.

The cut, etched surface of the meteorite shows a Widmanstätten pattern with tiny round troilite modules.

It also contains isolated grains of olivine, troilite and kamacite in a gray matrix.

Kamacite, troilite and chromite are also present.

The ideal FeS lattice, such as that of troilite, is non-magnetic.

The larger pieces also contain small amounts of cohenite, ilmenite, pearlite and troilite.

The rare stoichiometric FeS endmember is known as the mineral troilite.

Other accessory minerals include troilite, whitlockite, and cohenite.

Vermicular sulfide (troilite) is present in some olivine.

This temperature is close to the condensation temperature of troilite (FeS).

The troilite plates are called Reichenbach lamellae.

W0: no visible oxidation of metal or troilite, but may be noticeable in transmitted light a limonitic staining.

W1: small oxide rims around metal and troilite, small oxide veins.

Minerals present include taenite, plessite, troilite, chromite, kamacite, and schreibersite.
