I've not heard of Molybdenite in massive veins like this as it forms in
metamorphosed sea deposits--aka Marbles in small hexagonal clusters of
flat soft malleable crystals. While it shares a "1" in hardness with
graphite it is harder than graphite but will still leave a strea
Hi Mark, I sat down and rubbed it hard with my thumb, polishing a flat spot,

Hi, OK I put up the pics of the streaks, The Molybdenite streak is bluer
that the suspect sample.
Pic 1 on the left has the streaks mounted in a horizontal fashion. MoS2 is
on the bottom. It is bluer than the sample streak at the top. Pic 2 has the
streaks mounted in a verticle position. MoS2 is
OK, I had a piece of Molybdenite lying around, and I had a small ceramic
crucible.
I did the scratch test. The Molybdenite,(molybdenum di-sulphide), obviously
left a mark like a soft grey lead pencil.
Then I rubbed the suspect Mo sample on it and to my surprise, it left the
