Abstract
The American Upper Ordovician Standard, XVIII: Investigation of Micrite in Typical Cincinnatian Limestones by Means of Scanning Electron Microscopy
Cyril F. Lobo, Robert H. Osborne
ABSTRACT
Scanning electron microscopy was used to study finely pulverized skeletal material extracted from typical Cincinnatian limestones as well as micritic regions within slabs of associated limestones. Samples were observed at magnifications ranging from 3,000 to 30,000 . Fibrous, platy and lamellar organic structures were recognized in the less than 5 ยต size range both in the pulverized, particulate samples and in the micritic regions of limestone slabs. Although micrite may be polygenetic, at least part of the micrite included in the sampled limestones was derived by the comminution of skeletal material.
