Abstract
Lacustrine sediments from the 24 km diameter Boltysh impact structure record the rapid formation of an intra-crater lake. Stable isotope compositions and organic maturity parameters from the lake sediments deposited post-impact show that they were heated by underlying impactites. This heating is attributed to the establishment of an impact- generated hydrothermal system. Estimates of the duration of heating are ~30 – 40 k.y. consistent with the suggestion that crater lakes extend the longevity of impact-generated hydrothermal systems.
