Ejecta deposits are geological formations composed of materials that have been ejected from a volcanic eruption or impact event. These deposits can range in size from tiny ash particles to large boulders and can cover vast areas surrounding the eruption or impact site. Ejecta deposits play a critical role in understanding the dynamics of volcanic eruptions and impact events, as well as in reconstructing past geological events. Scientists study these deposits to learn more about the timing, intensity, and effects of these events on the surrounding landscape. Additionally, ejecta deposits can provide valuable information about the composition and behavior of the materials ejected during these events.
