One reference I read said the area around Fordo was Limestone and Dolostone, whatever that is. Limestone is rock, but it isn't granite.  I have no clue how strong Dolostone is.

Hmmm... Limestone and dolomite are sedimentary rocks, which doesn't jive with the geologic map indicating volcanic rocks.

In trying to research this, I ran into a disinformation site (with "lies" in its name) that referenced a non-existent journal and an article name (that doesn't show in Google anywhere but that page) as the source of the kind of rocks.  Beware....

I did run into a page (with "weather" in its name) that makes the claim of these rocks and suggests that the energy absorption of the sedimentary rocks, with earthquake-fractured strata, would protect the Fordo site.  Maybe that's a legit page from the region, but I'm not sure. (The claimed date of publication is before the bombing, but I have no way of validating that.)

Ah, here's a reference I believe may be legit, indicating that a former Israeli official said that it was under limestone.

Here's a reference on crater formation in sedimentary rocks vs igneous rocks, which supports the fact that sedimentary rocks absorb a shock wave better.
