Search for the Impact Crater of the Australasian Tektites

The site of the extraterrestrial impact that produced the Australasian tektite strewnfield has never been found. We suspect that the ~800,000-year-old impact crater, from which this horizon of ejecta were scattered across 10% of Earth’s surface, lies buried under the voluminous Bolaven Plateau lavas of Southern Laos. We propose to continue our initial efforts to solve this long-standing mystery. In so doing we anticipate contributing also to the characterization of volcanic hazards, constraints on incision rates of the Mekong River that will aid in evaluating earthquake hazards farther north, and to strengthening collaborations with colleagues and institutions in northern Southeast Asia.
