Shield Posted September 4, 2020 Share Posted September 4, 2020 Hello, my friend and I recently developed interests in minerals in a particular area. Could anyone help identify this. It was located roughly 100yds to what we believe to be a undiscovered meteor crator. Quote Link to comment Share on other sites More sharing options...
Morlock Posted September 4, 2020 Share Posted September 4, 2020 Well..,it's definitely not a meteorite. Put some warm vinegar on it. If it fizzes, it's calcite. It'll be a slow fizz so you'll have to watch it for it. Quote Link to comment Share on other sites More sharing options...

Shield Posted September 5, 2020 Author Share Posted September 5, 2020 Im curious about this also. It doesnt look like other Kimberlite rocks we have. Quote Link to comment Share on other sites More sharing options...

Looks like either quartz or calcite. The vinegar test will help indentify it. Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted September 5, 2020 Share Posted September 5, 2020 It looks like flourite from the geometry. The larger, well developed crystals anyway. Lots of white calcium in between. So my guess is flourite and calcite. Quote Link to comment Share on other sites More sharing options...
fuss Posted September 5, 2020 Share Posted September 5, 2020 First one could be a carbonate rock or maybe even a quartzite, tough to say unless you can do the test Morlock suggested. Though a hardness (scratch) test would also be a good idea especially on the large protruding mineral as well as the general surface. Second one looks more like quartz to me than Fluorite and a hardness test will be an easy way to determine that. A steel knife will scratch Fluorite but not Quartz.
