This ancient crater, estimated to be over 3.5 billion years old, surpasses the previous record-holder by more than a billion years. The discovery was made during fieldwork in May 2021, where researchers found shatter cones—distinctive geological features indicative of meteorite impacts—in the area. This finding supports the theory that such colossal impacts played a pivotal role in the formation of Earth's early continental crust. The identification of this crater not only provides tangible evidence of early meteorite impacts but also offers insights into the processes that shaped our planet's primordial landscape. The presence of spherules—tiny droplets formed from molten rock ejected during impacts—within the crater's vicinity further corroborates its meteoritic origin. This discovery opens new avenues for understanding Earth's formative years and the external forces that influenced its geological evolution. P. Geo. Ricardo A Valls, M.
