{"title":"Iron, IVA","description":"\u003cp\u003eIVA Iron meteorites are a well-defined group within Iron meteorite classification, representing material from the metallic cores of differentiated asteroids. Formed over 4.5 billion years ago, these meteorites crystallised from molten metal as their parent bodies cooled over extended periods. The ‘IVA’ designation reflects their specific nickel content and trace element chemistry, which distinguishes them from other Iron groups and indicates a unique cooling and formation history.\u003c\/p\u003e\n\u003cp\u003eIVA Irons are composed primarily of iron-nickel metal and often display well-developed Widmanstätten patterns when cut and etched. These patterns can vary in scale, with some specimens showing finer structures and others displaying broader crystalline features depending on composition and cooling rate. IVA meteorites are also known for sometimes exhibiting structural variations, including areas of different crystal sizes within a single specimen, reflecting complex cooling conditions within their parent body.\u003c\/p\u003e\n\u003cp\u003eStudying IVA Iron meteorites provides valuable insight into the diversity of core formation and cooling processes in early planetary bodies. Their distinct chemical and structural characteristics help scientists better understand how different asteroid cores evolved over time. For collectors, IVA Irons are highly desirable due to their recognisable patterns, relative scarcity compared to more common groups, and scientific importance. Each specimen represents a well-defined example of ancient metallic core material from the early solar system.\u003c\/p\u003e","products":[{"product_id":"gibeon","title":"Gibeon - Iron, IVA  -  Complete Individual  -  5.47g  -  Namibia","description":"\u003cp data-start=\"26\" data-end=\"533\"\u003eGibeon is a classic IVA Iron meteorite from Namibia, first recognised scientifically in the 19th century after earlier use of the material by local peoples.
