Siderite (Noun)
Meaning 1
A meteorite consisting principally of nickel and iron.
Classification
Nouns denoting natural objects (not man-made).
Examples
- The siderite that fell to Earth weighed over 500 kilograms and attracted scientists worldwide to study its composition.
- After conducting a series of tests on the sample, researchers determined it was primarily a mixture of iron and nickel, hence a siderite.
- The Chelyabinsk meteorite was initially thought to be stony in composition, but a microscopic analysis revealed it was likely a siderite, composed mostly of metal.
- The fragments of the newly discovered meteorite were rushed to the laboratory for analysis, where it was confirmed as a siderite due to its characteristic metal-rich composition.
- Geologists predicted the celestial object's iron content was exceptionally high, leading them to believe the object to be a siderite meteorite before conducting further research.
Meaning 2
Iron ore in the form of ferrous carbonate.
Classification
Nouns denoting substances.
Examples
- The siderite deposit was discovered in a limestone cave system after extensive geological surveys.
- During ancient times, siderite was a primary source of iron used in tools and other metallic items.
- Mining companies focus on processing siderite to separate the iron content for industrial use.
- Historical iron production relied heavily on siderite due to its relative ease of processing.
- Geologists consider siderite an economically viable alternative to other iron ore sources due to its iron content.
