North Pole Dome Stromatolite Australia — 132 g

This authentic North Pole stromatolite is an extraordinary early stromatolite (microbial mat fossil) from the Dresser Formation, Western Australia. It is a premium specimen featuring distinct microbial laminations and chert-barite mineralization dating to deep time, approximately 3.5 billion years ago, representing some of the oldest widely accepted evidence of early life on Earth.

North Pole Dome Stromatolite, Dresser Formation, Pilbara, Australia

The North Pole Dome stromatolites from the Dresser Formation in Pilbara, Western Australia, are among the oldest Archean-age life-related structures known on Earth, dating to approximately 3.5 billion years ago. These stromatolitic microbial mat structures contain layers of quartz, barite, and chalcedony, interpreted to have formed in association with shallow-water hydrothermal systems active at Earth's surface.

Geological Significance

The North Pole Dome region of the Pilbara Craton preserves some of the best-exposed and best-studied sections of ancient Archean crust on the planet. Episodic hydrothermal fluid activity near the ancient surface contributed to the formation and preservation of diverse stromatolite morphologies, reflecting dynamic early Earth environments.

Diverse Geology

The North Pole Dome and the surrounding Pilbara region exhibit exceptional geological diversity. Barite lenses are common within the Dresser Formation, with barite migrating through sills, veins, and fractures to the surface. These features provide substantial evidence for early hydrothermal circulation, tectonic activity, and chemical conditions on the early Earth.
