picking up where I left off....
Mood:  vegas lucky
Topic: geology et al
It has been ages. I can only blame it on confusion in my life, including health issues.

Not sure where I left off. I think it was with the sphalerite group of sulfides. The copper sulfides include chalcopyrite, stannite, and bornite. As a collectible ore, bornite is popular because of its appearance. It is called peacock ore and has a purplish blue tarnish. The chalcopyrite is an important copper ore and it alters naturally to malachite, azurite and limonite. These are extremely popular sulfites. Personally I find their colors too strong and lacking in sublety. And these are soft stones.

Writing. I got nowhere on my endeavors to hold a writers workshop at church but since failing miserably, two women have offered to prepare a supper and try to entice the facilitator back.
