The following are some pseudomorph minerals I cut open on my saw last night. I'll show photos front and back of the two specimens, each of which are several inches long. To me, they both appear to be quartzite or florite after barite, but I'm not really a mineral guy so I would happily defer to anyone that can describe them better. Thanks for the help.

Here are several stones I cut up this past week to see what was inside. They all came from the Four Corners area of the U. S. I would describe them as follows: 1. about 6 inches wide; an agate and jasper mix. 2. a dark but translucent chalcedony partially filled with horizontal crack and some yellowish/brownish plume agate is visible there; there are small, mostly horizontal oriented flecks visible throughout the stone that appear to be pyrite. 3. a thunder-egg with lots of bluish agate. 4. I call this New Mexico Brawn since it reminds me of a slice of head cheese. brecciated stone with really blue agate and yellowish jasper. 5. looks like a yellow jasper stone with a distant nebula peeking through the cracks. 6. a lovely agate-after-barite stone.

I acquired some local Island minerals the other day from an old rockhound up-Island. As is typical, she couldn't tell me where each one is from other than "Vancouver Island", so I'm looking for that info (for some of them I have an idea). Also not sure what some of them are so am looking for that info as well. Garnets, possibly from a mine in the mid-Island area. I was impressed when saw some of these when I did a fossil presentation for the Parksville Rockhounds (but didn't make a note of the mine they came out of), and then lo and behold, this lady had some! I will get ahold of someone from that club to see if they can tell me where they're from. Also I'd like to know if there is a surefire method of removing that iron oxide coating that covers a lot of our local minerals.
