Diverse Ancient Volcanoes on Mars Discovered by HKU Planetary Scientist May Hold Clues to Pre-plate Tectonic Activity on Earth

HONG KONG SAR – Media OutReach Newswire – 20 February 2024 – Volcanoes are a common feature on the surfaces of solid planets within the solar system, resulting from magmatic activity occurring within the planetary crust. On Earth, volcanism is driven primarily by heat and crustal recycling associated with plate tectonics, but Mars lacks plate tectonics and the driver of volcanism is not well understood.
