{"title":"Iron, IVB","description":"\u003cp\u003eIVB Iron meteorites are a rare and chemically distinctive group within Iron meteorite classification, representing material from the metallic cores of highly differentiated asteroids. Formed over 4.5 billion years ago, they crystallised from molten iron-nickel metal under conditions that differed from most other Iron groups. The ‘IVB’ designation reflects their unusually high nickel content and unique trace element composition, indicating a separate and specialised formation history.\u003c\/p\u003e\n\u003cp\u003eIVB Irons are composed primarily of iron-nickel metal but often lack well-developed Widmanstätten patterns due to their high nickel content. Instead, they may display a more uniform or fine-grained metallic structure when cut and etched. This sets them apart visually from many other Iron meteorites, where large crystalline patterns are more typical. Their structure reflects different cooling conditions within their parent body, resulting in a distinct internal texture.\u003c\/p\u003e\n\u003cp\u003eStudying IVB Iron meteorites provides valuable insight into alternative pathways of core formation and crystallisation in early planetary bodies. Their unique chemistry helps scientists understand how variations in composition influence cooling and structure within metallic cores. For collectors, IVB Irons are highly desirable due to their rarity and unusual characteristics. Each specimen represents a less common type of core material, offering a different perspective within Iron meteorite collections.\u003c\/p\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/0518\/8678\/collections\/Collection_Place_Holder_740bcfe2-b69c-4e09-b1d4-fc41cca44e9f.jpg?v=1779301544","url":"https:\/\/outerspacer.com\/collections\/iron-ivb.oembed","provider":"OuterSpacer Meteorites","version":"1.0","type":"link"}
