Meteor impact??

[drumlishlad]

Attached are images of rock used in the wall of a building in the centre of Ireland.
It is approx 12 x 10" in the view shown.

There are two types of rock, one seems to have been deformed by pieces of the second material at points A, B, and C.
At point D it in addition to having been deformed it appears that the second rock also 'flowed' around part of the first one.
Our thinking here was along the lines of volcanic origins or impact from a very hot meteorite.
Since we have no knowledge of volcanic activity in Ireland we are leaning towards the meteor theory.
Really, we need an expert to tell us what it is, when the event likely occurred and is it very rare.
Of course ' a good story' would also be very much appreciated
Looking forward to your comments.

The photos are insufficient for me to tell what kind of rock is present. I would need more detailed close-ups of each of reported impact(s).

I'm not certain that impact "C" and "D" are separate structures. They appear to merge. Also, there may be another impact at the upper-right hand of photos 1 and 2.

As you have already denied a volcanic rock origin, can you tell us if this is mostly limestone?

The photos are sufficient enough to tell me you need to back off on the Guinness.

The material inside what you have believed are impact areas, appears to be Flint and the host rock appears to be Limestone! If this is correct, then the areas noted around subject rocks "A", "B", "C" and "D" are nothing more than weathering of the softer Limestone material which exposed more of the harder Flint.
