    It's only light when someone else gets to lift it, just like furniture.

    New news-They are now being sold by B&H (under Gitzo,not Manfrotto-although Bogen is the distributor company).B&H has no images,specs,or details listed with them.

    only the prices(the lowest being around $270.00 U.S.-for one that can hold about 4.5 lbs) and that they are special order.
    They are refferred to as "sport Basalt tripods","reporter",etc.

    Even more exciting news!
    It turns out that this tripod has been designed specifically in conjunction with the long awaited re-release of the Hasselrock 1000000BC (better known as that Flintstone camera with the bird inside that chisels the picture into a little stone tablet with his beak).
    That is called grain. It is supposed to be there.

    Basalt consists of about 48-52% silica (SiO2). Other major elements in varying proportion include titanium (TiO2), aluminum (A2O3), iron (FeO or Fe2O3), manganese (MnO), magnesium (MgO), calcium (CaO), sodium (Na2O), potassium (K2O, and phosphorous (P2O5).

    Gitzo pulverises basalt, melts it and adds some pixie dust, then spins it into fibers. The result is a glass/metal composite fiber that is woven and laminated with epoxy into a tube structure. Then Gitzo PR takes over...

    Still, basalt is considerably heavier than e.g. granite...

    Probably includes a lot of air, most of it hot.

    This being stated(the makeup of basalt)I have a question.
    First I have two tripods(one aluminum,one carbon fiber).From what I understand(I may be wrong)wood tripods allow less vibrations to reach the tripod head than the above.How would in comparison a tripod with all those
    elements(of basalt) compare in this regard-worse,better or about the same?
    The ones listed at B&H are pricey for the load capacity-would it be any real
    improvement from a scientific viewpoint.

    In this case I would consider a fully organic carbor-fiber compound, which is what my tripod is made of: Wood.
