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 forms on our planet. These stromatolitic microbial mat structures contain layers of quartz, barite, and chalcedony formed from hydrothermal vent fluids. Scientists believe these stromatolites thrived in a shallow-water, open-air environment.
Geological Significance
The geology of the North Pole Dome region in the Pilbara Craton, Western Australia, features some of the best-preserved and well-exposed sections of ancient Archean crust on Earth. Episodic fluids deposited hydrothermal vent effluents near the ancient surface, creating diverse stromatolite formations. These variations in appearance and form highlight the abrupt, widespread, and unique nature of hydrothermal vent activity in the region.
Diverse Geology
The North Pole Dome and the Pilbara region boast immense geological diversity. Barite lenses are abundant in the North Pole Dome succession, with barite percolating through sills and veins to the surface. These formations are crucial indicators of active tectonic processes and essential for understanding the geology and tectonics of Pilbara.
