Bornite, Slickensides

Item number: 20993

This specimen is rock, heavily laced trough with veinlets of bornite and disseminated bornite. It is not solid bornite but there is lots of bornite in it plus, I think a fair bit of chalcocite. The interesting thing is that on two sides, there are prominent slickensides that are composed of copper sulphides. Slick! (Pun intended).
