Search for microaustralites in deep‐sea sediments less than 20,000 years old
— Several authors have proposed that australites fell less than 20,000 years ago. We searched for microtektites in the tops of 46 deep-sea cores and were unable to find evidence for a microtektite layer less than 20,000 years old. Either the australite fall was not accompanied by microtektites, or the strewnfield did not extend into the area searched, or the australites fell about 0.77 Ma ago as indicated by their radiometric ages.
