Cool rock. The region you found the stone in is built with basalt. Geologically violent area with earthquakes, volcanoes, and old basalt flows. I think what you have is shattered basalt, no doubt earthquake damage, that remained in place buried deep underground, and the cracks were infilled by rich volcanic fluids leaving behind all the quartz. It formed in the hot plastic zone, the quartz inclusion have been deformed, bent, post formation. IMO.
Thank you! I will keep it as a conversation starter on my coffee table. š itās definitely worth keeping since itās unique with all the different formations.

I found a rock in the Willamette Valley It is some kind of metal, very hard, heavy and non magnetic. My MXT was screaming about it. I kept looking for a coin or jewelry, only seeing rocks until the pointer distinguished it from others in the hard dirt. Is it worth looking into? Should I take it to the geology dept at the University?
BTW, new here, just started MDing..... A lot of nice folks on this forum.
