Search for the Impact Crater of the Australasian Tektites

Over the past few years, we assembled evidence that the impact crater of the Australasian tektites lies beneath the Bolaven Plateau volcanic field in Southern Laos. Geochronological, gravimetric and sedimentologic tests in FY2017 further support the hypothesis. In FY2018 we will publish three papers about the impact site and the volcanic field. We will also examine compositional heterogeneities within individual tektites for hints about impact target complexities and further examine the two widespread sedimentary products (the catastroloess and pebbly laterite), to understand impact processes. We will also expand our understanding of the hazards posed by the Bolaven Plateau volcanic field.
