Summary
[edit]DescriptionCalcite on chert breccia (Tri-State Mining District, Missouri, USA) 2.jpg |
English: (CMC RM1203, Cincinnati Museum of Natural History & Science, Cincinnati Museum Center, Cincinnati, Ohio, USA)
The dark orangish-brown mass is a large calcite crystal. Calcite is a common calcium carbonate mineral - CaCO3. It is the dominant component in common rocks like limestone and marble. This example is from Missouri's Tri-State Mining District. The matrix / host rock seen at left is a chert breccia, a scarce lithology. Breccia is a poorly sorted rock with angular large grains. In this case, the large grains are composed of chert, a quartzose, cryptocrystalline sedimentary rock. Locality: unrecorded/undisclosed site in the Tri-State Mining District, southwestern Missouri, USA |
