Category:Building stone
[edit]I have made Category:Building stone a sub category of Category:Sedimentary rocks but have not completed the job of of the necessary transfer of building stones from the Category:Sedimentary rocks list. I thought it best to give people an opportunity to comment before going too far. There is the problem of the granite and marble building stones which are not sedimentary but a Building stones category would be useful to people interested in architecture, for example.
