Scientists have discovered a massive 12.4-mile-thick, unusual rock layer beneath Bermuda, challenging existing geological models and potentially explaining the island's persistent oceanic swell despite the absence of recent volcanic activity. This layer, a remnant of ancient volcanic activity linked to the breakup of Pangea, offers new insights into Earth's tectonic processes and Bermuda's unique geological history.

Geologists have discovered a 400-mile-long chain of fossilized volcanoes beneath the Sichuan Basin in southern China, dating back around 800 million years. This find sheds light on early Neoproterozoic tectonic activity, particularly the process of flat-slab subduction, and has implications for understanding Earth's geological history and climate regulation during that era.

Geologists have completed mapping Zealandia, a submerged landmass considered Earth's eighth continent, covering nearly two million square miles. The research involved analyzing rock samples from North Zealandia, revealing its geological history tied to the ancient supercontinent Gondwana. Despite being mostly underwater, Zealandia's mapping highlights its significance as a geological entity.

Geologists have discovered the submerged continent of Zealandia, twice the size of India, beneath the southwest Pacific Ocean. A new geological map has been compiled using rock samples and geophysical mapping methods, revealing large sandstone formations and basaltic rock pebbles that suggest Zealandia was gradually flooded around 40 million years ago. The study, "Reconnaissance basement geology and tectonics of North Zealandia," was published in the journal Tectonics in 2023.

Valles Marineris on Mars, the grandest canyon in the Solar System, likely formed from a combination of processes including a giant impact that created Mars's moons, volcanic activity, and tectonic forces. The canyon, spanning 4000 kilometers across and up to 7 kilometers deep, was likely widened and deepened by erosion, landslides, and subsequent impacts. Mars's unique geological history, including the formation and destruction of a transient moon, contributed to the creation of this impressive feature, showcasing the planet's fascinating past and geological diversity.
