Komatiite Barberton Greenstone Belt South Africa [61 gm ~ 3.5 Ga]

Komatiite Specimen from Barberton Greenstone Belt

Discover the rare beauty of komatiite, an ultramafic volcanic rock, from the renowned Barberton Greenstone Belt in South Africa. This region is celebrated for its well-preserved komatiite sequences dating back to the Archean age (approximately 3.5 - 3.3 billion years ago).

About Komatiite

Komatiites are magnesium-rich volcanic rocks formed from ultramafic magma. Named after the Komati River in South Africa, where they were first described by Dr. Alexander du Toit in 1908, these rocks offer a glimpse into Earth's early history and the evolution of its crust.

Features of Barberton Greenstone Belt Komatiite

• Contains some of the best-preserved komatiite sequences in the world, with thicknesses ranging from a few meters to over 1000 meters.
• High proportion of spinifex textures, indicating rapid cooling of ultramafic magma at temperatures up to 1600°C.

Significance

The abundance of komatiites in the Barberton Greenstone Belt is significant due to their rarity on Earth today. Changes in the Earth's mantle over time have reduced the production of ultramafic magma, making these ancient rocks invaluable for studying the geologic processes of the Archean Eon.
