I'm a palaeontological preparator and I have tested a lot of
adhesives on rocks and fossil bones. Many of the fossils I work on
are embedded in limestone. I think marble and limestone can be
treated the same way. Most of the time I use 2-component
Epoxy-resin-glue. There are many good systems on the market like UHU
Endfest, Araldite 2011 or 2020. See
<URL:http://www.araldite-adhesives.com>. When you mix the two
components just add a little powder-color or marble dust to give the
glue the same color as the table.

Another possibility is the use of Akemi Marble Filler. This is a
polyester based system for all kinds of natural stone. In Germany
this is widely used by stonemasons. There are several colors
available on the market. See <URL:http://www.akemi.de>. I think
Paraloid B-72 is not strong enough for this.
