How old is stone
Arthur; I may be showing my ignorence here, but your question
prompted me to do a little research. In Texas, the limited
soapstone formations are found in schists that are metamorphised
pre-cambrian sediments. The metamorphism occured prior to the
deposition of the overlying cambrian sediments. These
formations are dated to about 1.2 billion years. I am not
familiar with the geology of the Appalacian Mountains other than
knowing that they are very ancient in their formation, so I
suspect that the great soapstone deposits around Schuyler,
Virginia are pretty old also. As far as I know, soapstone
deposits are always associated with metamorphism, and since it
does take a long time geologically speaking for sedimentary
rocks to become metamorphic, I would imagine that most soapstone
deposits have been around for a while. ( someone please correct
me here if I'm way off base). Hope this helps,
John VanCamp
