The discovery of a 4km-diameter meteorite impact crater in Western Australia's Eastern Goldfields has sparked excitement and intrigue, particularly due to its proximity to the historic gold mining district of Ora Banda. This site, now known as the "Ora Banda impact structure," is significant for several reasons, offering a unique glimpse into the geological past of the region. The crater's target rocks, ancient greenstones, are not only valuable for their potential gold content but also for the insights they provide into the impact event itself. The presence of shatter cones, shocked quartz, and extraterrestrial meteorite residue serves as compelling "smoking gun" evidence of the impact, confirming the site's ancient origins. Moreover, the discovery of gold particles within the breccia deposits adds a layer of intrigue, suggesting that the impact event may have resulted in a "raining" of gold onto the surface. This finding not only highlights the unique nature of the geologic setting but also underscores the potential for further exploration and discovery in the region. The Ora Banda impact structure, along with other recently discovered craters in Australia, contributes to a growing body of knowledge about meteorite impacts and their impact on the Earth's surface over geological time scales.
