There is a single 0.75mm black crystal at the arrow plus a black zone, which is probably also Melonjosephite. The matrix is Triphylite, perhaps partially altered to Melonjosephite. The type locality description notes that Melonjosephite is an alteration of an Alluaudite group member. But, it is interesting to note that at the type locality, Angarf-South pegmatite, Alluaudite is not found (according to Mindat). Furthermore, Alluaudite is only noted at only two of the five pegmatites where Melonjosephite is found. So it may be worth examining your specimens of Melonjosephite to determine which Alluaudite group mineral is associated.

There's a lot going on with this specimen. It is basically a siliceous brecciated piece which was probably created by hydrothermal activity which pumped the mineral solutions into the rock. The mine was or is the one of the largest gold deposits in the world, which is on the so-called Carlin trend in Nevada. It not only produced gold but also produced a lot of rare minerals, mostly phosphates. On this specimen is sky blue fuzzy Nevadaite, rusty red Hewettite and bright lime green Torbernite (Raman ID) crystals. There are also waterclear beads of Hyalite opal which seems to have taken a liking to the Torbernite as it is closely associated with it. It's a cool peice.
