This week's microscopic view is from the Mississippian limestones exposed in the southern Appalachian mountains of Alabama.
Ooid cortices made up of tiny radial crystals of calcite growing around a foraminifera nucleus.
I will be putting up a longer post on ooids and oolite facies as important contributors of carbonate sand through geologic time and their significance as indicators of sea water chemistry and ecologic disruptions.
Stay tuned.
