I dunno and really don't care too much, just bought this stuff from the same seller because I thought it was cool. If you have any better names or Fill in the Blank information, I would like to hear it! Maybe all from Arizona, but locations were not given on most of the material. #1 - Called this Conglomerated Calcite, Quartz, Augite & Unakite  backside  Now, this slab, obviously form the same rock he called: #2 - Quartz, Hematite, Augite, Epidote - - where did the Calcite & Unakite go?  #3 - This was called simply Conglomerated Quartz (?)  backside  #4 - Called this Conglomerated Quartz, Hematite, Augite, Feldspar  backside  #5 - Now this stuff he called Brecciated Quartz with Hematite, Calcite, Epidote  #6 - Yet this he called Scenic Dolomite (from Arizona) - - okay...  backside  #7 - This was identified as Brecciated Hematoid Quartz  #8 - And this simply listed as Brecciated Jasper  Brecciated Jasper side  Ya'll have any insight as to the correctness of the names and/or where they may be from? Thanks for looking |

Wow, what a display of complex stones. Conglomerate is sort of a catch all term for a rock that is composed of other rocks or pieces of other rocks all cemented together by some mineral or another. If the included pebbles are well rounded, we often call them "puddingstones". A breccia is different, being basically a rock that has shattered or broken apart and them been cemented back together. In a breccia the included fragments are fairly homogeneous whereas in a conglomerate, the included pebbles or fragments are often all kinds of different stuff. Looks to me, though I am unsure of the various mineral types, that the general category IDs you got with those are pretty spot on.....Mel

Every one is just awesome, and color, omg.... love the breccias and conglomerates. All AZ collected you say? I am just learning how breccias and conglomerates can be formed by meteor/ite impacts... any chance some or all of these came from impact sites or near one?
Those are just great!

Those are just great! Snowmom, the seller listed some of the pieces as being from Arizona. I don't know that all came from there. Nor have any idea on specific sites of origin. As to whether they may have been formed with extraterrestrial help - I haven't a clue. Like I said, I just thought they were cool.  |

To answer your question about unakite, it is made of the minerals epidote and feldspar. So he seems to be using one of the mineral names in some places and the rock name of unakite in others. I'm not sure if any of it is correct or not, but at least it makes some sense.
