Stone not only comes from different holes in the earth but from
different levels and w/ a sedimentary stone it depends on what was
living at the time of the deposition.
If you want fossils then you specify from the fossil layer. If you don't
want fossils then you specify from the non-fossil layers.
The layers have names, of course.
Reference: 'Prospecting Cordova Limestone in Central Texas' in 'Eight
Stones and Many Feet' by Gabriel Orgrease wherein the goal of the
protagonist is to locate the mysterious origin of the particularily
fossiferous stone specified by the architect for use on the San Jacinto
Monument resotration.
As to alternation of stones etc. there is such a thing as
'relationships' between the designers & builders that would lend
themselves to a depth of involvement in the design-build process. And
architects do go visit quarries and they do talk w/ quarriers and they
do get into selecting stone down to the individual piece at times....
though not always.
Limestone comes from a lot of places besides Indiana & Kentucky. You may
also check w/ the Building Stone Institute. There are many quarriers as
members and they do maintian a stone library.
A problem nowadays is that stone that may have been quarried from a
certain hole at a certain level 50-100 years ago is no longer quarried.
It is not that the stone is not there in the earth as much as that there
is not an economy to the industry to support quarry of that particular
stone.
