Here are some excerpts from Allan's report:

                           MARTIAN ORIGIN OF THE
                              "FRASS ROCK" OF
                      MR. MICHAEL MOORE, AMARILLO, TX.

                              Allan H. Treiman
                          Senior Staff Scientist
                          Lunar and Planetary Institute
                                 Houston, TX
                                March 22, 1999


             Mr. Michael Moore of Amarillo Texas reported to his
         Senators and Congressman that he possessed a meteorite
         from Mars, and requested that NASA study the object. His
         request was forwarded, through the NASA Legislative
         liaison officer, to Dr. Allan H. Treiman of the Lunar and
         Planetary Institute, TX. Dr. Treiman is an expert on
         martian meteorites.

             The object, a rounded boulder of bubbly basalt lava
         rock, is not a meteorite and is not from Mars.

             The boulder cannot be considered a meteorite as it
         shows no fusion crust, the glassy melted coating that
         develops on all rocks from space as they burn through the
         Earth's atmosphere.

             Although the known martian meteorites are basalt lava
         rocks (or closely related), Mr. Moore's basalt rock is
         not martian: it is from the Earth. This conclusion is
         based on chemical elemental analyses of the rock. With
         the available chemical data, ten distinct tests a
         basalt's planetary origin could be applied to Mr. Moore's
         basalt. None of the tests suggests that the rock formed
         on Mars; all of the tests show that it is similar to
         Earth basalts, and so must have formed on Earth.


       The Frass rock cannot be considered a meteorite, in any
       normal sense of the term, as it shows no evidence of having
       come from beyond the Earth. It is not covered with a fusion
       crust, the melted layer that develops on rock meteorites as
       they pass through the Earth's atmosphere. If, indeed, the
       Frass Rock were a meteorite and had fallen the day before it
       was collected, it must show some evidence of its passage
       through the Earth's atmosphere. Nor does the chemical
       composition of the Frass Rock suggest an extraterrestrial
       origin. Every chemical test that could be applied is
       consistent with it having formed on Earth.

       The Frass rock cannot be considered martian, based on
       our current knowledge of martian basalts. No test of the
       Frass rock's chemical composition requires that it be
       martian; every test is consistent with an Earthly origin.
