Telluric iron is an extremely rare metal, found only in a few place in the world.

Telluric iron has lower nickel and higher carbon contents.

However, telluric iron typically contains only around 3% nickel, which is too low for meteorites.

There are two types of telluric iron.

Telluric iron is extremely rare, with only one known major deposit in the world, located in Greenland.

Meteoric iron can be distinguished from telluric iron chemically.

Telluric iron resembles meteoric iron, in that it contains both a significant amount of nickel and Widmanstatten structures.

Telluric iron, which is an iron-nickel alloy very similar to meteorites, also displays very coarse Widmanstatten structures.

Telluric iron, also called native iron, is iron that originated on Earth, and is found in a metallic form rather than as an ore.

Apart from minor amounts of telluric iron, meteoric iron is the only naturally occurring native metal of the element iron on the Earth's surface.

Telluric iron is metallic iron, rather than an ore (in which iron is usually found), and it originated from the Earth rather than from space.

Before the advent of iron smelting, meteoric iron was the only source of iron metal apart from minor amounts of telluric iron.

When investigations were made two masses, Cranbourne 001 and 002 were found buried at their original impact site that had been mistaken as an outcrop of an telluric iron deposit.

In 1871, on his second expedititon to Greenland, Nordenskiöld collected three large samples of telluric iron, still believing them to be meteoric, and brought them back to Europe for further study.

Aside from a very small deposit of telluric iron in Kassel, Germany, which has now been depleted, and a few other minor deposits from around the world, the only known major deposits exist in and nearby the area of Disko Bay, in Greenland.

However, there are a very few areas on earth where truly native iron can be found.

One of the interesting geological features is the native iron found at the island.

Iron meteorites are easily found, because native iron is rare.

There are only a few places on earth where native iron is found which is not of meteoric origin.

Most of the native iron on earth is actually not in fact "native", in the traditional sense, to Earth.

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

Native iron in the metallic state occurs rarely as small inclusions in certain basalt rocks.

There1 was still native iron on Mars, of course, but none of that was available for Scranton.

On Earth cohenite is stable only in rocks which formed in a strongly reducing environment and contain native iron deposits.

Once the Fe is consumed, then oxygen must be stripped from the system to further reduce it and wüstite is converted to native iron.

Zecchi sanguine (soft) is a native iron oxide with clays, from Tuscany, and has a bright orange-red tone.

It is the only surviving iron furnace from the area's iron industry, which was the only completely native iron industry in the state.

Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people.

Wüstite (FeO) is a mineral form of iron(II) oxide found with meteorites and native iron.

Metallic or native iron is rarely found on the surface of the Earth because it tends to oxidize, but its oxides are pervasive and represent the primary ores.

The opening was barred by a heavy grille gate of dark wooden beams, the joints of the cross-pieces reinforced with gussets of hand hammered native iron.
