Caption: Cathodoluminescence light micrograph of a section of sedimentary limestone. The rock consists mainly of compacted sea-shell fragments cemented with calcite. The wheel-shaped sediment at upper centre is the spine of an Echinoid, suggesting that the rock is up to 200 million years old - very young in geological terms. Cathodoluminescence is light emitted when the specimen, placed in a special light microscope surrounded by a vacuum chamber, is bombarded with high-energy electrons. The method reveals fine detail. Compare with E415/071, which is an ordinary micrograph of the same specimen. More information available on request. Ref: MICROCOSMOS, fig. 7.31, p. 141
