New Paper About Impact Origin of and Crater Location for Stac Fada Member (Scotland)

New Paper About Impact Origin of and Crater Location for Stac Fada Member (Scotland)

Since 2008, there has been an ongoing discussion about
whether the Stac Fada Member of the Stoer Formation of
the northwest coast of Scotland as to whether it is the
result of either a volcanic caldera eruption or an
extraterrestrial impact. Earlier, it was argued to be either
a fluidised peperite or a volcanic mudflow. The most recent
paper supports the impact origin of the Stac Fada Member
and proposes the location for a possible impact crater
beneath Scotland. It is:

and the Lairg Gravity Low: evidence for a buried
Precambrian impact crater in Scotland? Proceedings of
the Geologists' Association. vol. 126, no. 6, pp. 742-761.
