Morlock Posted August 5, 2018 Share Posted August 5, 2018 (edited) I'm thinking calcite as well. Or perhaps quartz. Edited August 5, 2018 by Morlock Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted August 5, 2018 Share Posted August 5, 2018 It is calcite. On the left side of the rock you can see the parallel cleavage planes running through the specimen. Quartz does not cleave like that. This is calcite. You can use it for making cement, stucco or in any manufacturing process where calcium is required.

4meter Posted August 6, 2018 Share Posted August 6, 2018 Try the hardness test. Draw a small piece of quartz across the sample in question. If it leaves a scratch, the sample is Calcite, if not, then its probable Quartz. 1 Quote Link to comment Share on other sites More sharing options...
