Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series.It is by mass the most common element on Earth, forming much of Earth's outer and inner core.
Seymchan is a Pallasite Meteorite found in a dry bed of a river in the Magadan District, Russia, near the settlement of Seymchan, in June of 1967. It is classified as a Pallasite but some specimens are all iron and are called Seymchan Siderites.

Minerals are classified based on characteristics such as hardness and crystal shape (e.g., hexagonal, cubic). An example is Quartz Silicon dioxide (SiO 2). Quartz is the most common mineral in the Earth's crust. For example, the purple variety of quartz is called amethyst, and is the state mineral of South Carolina.
Trace fossils record the activities of organisms. Tracks, burrows, eggshells, nests, tooth marks, gastroliths (gizzard stones), and coprolites (fossil feces) are examples of trace fossils or ichnofossils.
History and properties of iron. Archeologists estimate that people have been using iron for more than 5,000 years, according to Jefferson Lab.In fact, it turns out that some of the most ancient iron known to humans literally fell from the sky.

In this article, an overview is presented of the status of the radiocarbon dating of iron-based materials. Recent advances include simplification in sample preparation and reduction in sample size for accelerator mass spectrometry measurements, and the potential use of rust as a viable source of material for radiocarbon dating.

The new specimens vary widely in their appearance with some being completely siderite (iron) while others areas of the meteorite are nearly all silicate (stony material) with a small amount of iron between the olivine. Others are a mix of both and can also show distinct boundaries between siderite and silicate areas.

Meaning: Stony or metallic object that is the remains of a meteoroid that has reached the earth's surface. Classified under: Nouns denoting natural objects (not man-made)
Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Iron was also known to early Asian civilizations. In Delhi, India, for example, a pillar made out of iron built in A.D. 415 still stands.
ataxite: An iron meteorite consisting of either pure kamacite, an irregular mixture of kamacite and taenite, or pure taenite. bolide: Exploding fireball. chondrite: Stony meteorite containing chondrules.
The meaning of its name is unknown, although its origins are Anglo-Saxon. Pure iron is a soft, lustrous, dark silvery-gray metal. Iron is a strongly reactive metal, being very reactive with acids, and forms oxides, commonly known as rust, with air and water.
