Seems that there were follow up studies after this one in 2008 which raise doubts about the conclusion that the lake was formed by an impactor. https://en.wikipedia.org/wiki/Tunguska_event
While the recent 2017 study cites core samples, earlier studies suggested that sediments were not a part of the lake formation. I don't think there's enough detail in the Wikipedia articles to really shed light on this. Every study seems to reach different conclusions.
