I'm trying to figure out what this is. I have been overwhelmed with all the info online.
I'm very interested in rocks/ minerals. My friend in middle georgia is clearing some
Land and I had to go see what was being unearthed! There is a fault on property
Part is biotite gnesis/feldspathic biotite gnesis and the other is mica schist/gnesis/amphibolite
This is 1 of many I'm trying to identify. Thanks
The white definitley looks like a feldspar, and the grey is probably quartz. Are there any other pieces with mica visible?
This is same rock from different angles. I do see some mica. Would this be called a conglomerate?
No, conglomerate has rounded (weathered) stones cemented together by later geologic processes. This specimen is almost certainly from a pegmatite or vein, igneous in origin.
I agree. This is from a pegmatite in the metamorphic rocks you have described. Pegmatites have larger crystals that the rock that surrounds them because they cooled slower. Conglomerate is a sedimentary rock made up of ROUNDED rocks and minerals bound together with sand and cement (emphasis added). Georgia is well known for the igneous and metamorphic rocks in the NW part of the state. Gold was found in the 1840s near Daloniga (SP?) an hour N of Atlanta.
