I was stoked about a roundish rock ball found on my Superstition Mountain rounds  Convinced- it was some sort of copper derivative A Cu bias…mostly After washing my ball I was fooled!  The predominant green spots turns out to be some sort of moss  got to try to put a good spin on this  I didn’t take it for purely granite! pretty damn neat.... |

I have a price of common opal that has some interesting moss too. |

A bunch of the rocks I saw today when I was out hounding had a ton of moss on them...they weren't rolling.  |

a hard 7” diameter piece
Lots of silica, feldspar mica,
biotite, and or, hornblende.
probably both
For its size its is remarkably heavy & dense !
In example the specific gravity is way up there
It must have lots included iron oxide in it.
Perhaps pyrit~ish
'cept don't see the gold speckling color
Overall its weight is
9 1/2 lbs.
that is a considerable weight
for rock this size...mostly

Cool looking 9lb jawbreaker!
What's the plan with it now? Will you cut it and see what the inside looks like or add it to the rock garden?

I'd have to cut it, at least in half, just to see what it looked like on the inside. The curiosity would kill me. |

Hmmm, Ed is collecting moss now? : ) Cool rock. Are you going to cut it open?

originally thought of sphere’n it
but it would take a massive industrial grinding process
that rock is super hard and dense
The other thing is the history this rock rolled.
We know it was once part of huge earthly conglomerate
That got broken up & danced - probably by glaciers-
over unimaginable eroding distances.
tumbling tumbling tumbing
wear wear wearing
through Biblical massive landslide & floods
Endless roll
billion & billions of eons
to be a rock
&
not to roll
gathering mohss
so I don’t know
what its future journey may be
but I'll bet it have something to do w/
Rock'n
