There are arguments that seismic waves from the Chicxulub impact did a superfrack job on the Deccan flood basalts and magnified their eruptions. See-

Gobekli Tepe and the Younger Dryas Impact Hypothesis

Gobekli Tepe and the Younger Dryas Impact Hypothesis

There are an interesting series of blog posts about various ideas about Gobekli Tepe, its archaeology, and an alleged association with the Younger Dryas Impact Hypothesis on the Lateral Truth blog. They include:

https://www.skepticink.com/lateraltruth/2019/01/25/martin-sweatmans-decoding-of-prehistory-incoherent-catastrophe/

The above blogs are about:

http://omnilogi.com/ancient/deluge/Sweatman-and-Tsikritsis-gobekli-tepe-comet.pdf

In the same journal, Mediterranean Archaeology and Archaeometry, another paper about a fringe version of a Younger Dryas impact senario is published. The paper is:

Jaye, M., 2019. The flooding of the Mediterranean basin at the Younger–Dryas boundary. Mediterranean Archaeology and Archaeometry, 19(1), 71–83.

http://www.maajournal.com/Issues2019a.php

As previously mentioned, Rebbeca Bradley also commented on Michael Jaye’s unique ideas about an Younger Dryas impact causing a truly global flood in:

https://www.skepticink.com/lateraltruth/2019/06/22/michael-jayes-just-so-story/

Carl Feagans also published a post on his blog about Micheal Jaye’s paper on the Global World-wide Flood and the Younger Dryas Impact. It is:

Regardless of how the platinum anomaly is interpreted, White Pond, a Carolina Bay predates
it and the Younger Dryas. Thus, the above paper further supports the idea that the Carolina Bays are not connected to Younger Dryas event as concluded by:
