Volcano... Or Giant Impact?

Volcano... Or Giant Impact?


In [meteorite-list] Volcano... Or Giant Impact? at
http://six.pairlist.net/pipermail/meteorite-list/2011-October/080522.html
Michael Fowler asked:

"My guess is that the impact was at an oblique angle, 
since we have many other impact structures without 
such pyroclastic like flows. 

Anyone know where the impact crater (if preserved) 
is in relationship to the flow deposits?"

The crater is hypothesized to lie under the Minch, which is a 
strait that separates the Isle of Lewis in the Outer Hebrides 
from the north-west Highlands of Scotland. If this is the case,
then it lies at the bottom of the Minch Basin and buried beneath 
Precambrian Torridonian strata and a thickness of Permo-Triassic 
and Liassic sediments that fill this basin.

Meteorite with coin embedded

The auction description stated:

“Lot 265 Iron meteorite with coin embedded Iron meteorite w
Iron meteorite with a coin marked Vittorio Emanuel, Italia. 
Victor Emanuel II, first king of a united Italy. Size: 2 3/8" D 
Weight: 2oz Condition: Very good”

Yes, it is amusing the different types of objects, which get 
confused and mislabeled as a “meteorite.”

Judging from the coin and picture, this object is a tourist
curio that people visiting Mt. Vesuvius once could buy as 
a souvenir  of their visit. Back in the 1800s and as late as
the 1930s, a person visiting Mt. Vesuvius, if they had right
guide, could for a small fee give him or her a coin and 
the guide would with the aid of metal tongs snag a piece
of semi-molten lava from an active lava flow and embed 
a coin in it as you watched. My mother, when she was in 
Italy during the 1930s, paid her guide to create such a 
souvenir from a coin that she had and lava. My sister
currently has this curious souvenir.

An example of such souvenirs is illustrated in “Fascist 
coin embedded in lava” at:
http://www.bbc.co.uk/ahistoryoftheworld/objects/cPGBddLLRTKFvEuerO6ulg

This practice is noted on page 104 of:

Scott, David Dundas, 1856, Italy, classical, historical and 
picturesque. Blackie and Son, London, England.
