“…No studied modern calcite planktonic foraminifera do show luminescence under CL, but almost all benthic porcelanous foraminifera show an orange emission. Recent aragonitic foraminifera are rare and have weak greenish luminescence (Barbin 2000). The luminescence intensity of Recent foraminifera from a given site is generally similar, but does show variation among samples from different environments and regions.…”

“…In order to get better insights into the preservation and variations in the abundance of foraminifers from Upper Jurassic and Upper Cretaceous deposits, the present study applies the simple cold CL technique. More complex techniques, including CL spectral analysis and high sensitivity (hot CL), can provide more detailed data on biomineralization, skeletal microstructures, environmental parameters and diagenetic history (e.g., Barbin et al 1991Barbin et al , 1995Barbin 2000;Kershaw 1994;Tomašových and Farkas 2005;England et al 2006).…”

Cathodoluminescence (CL) studies of LowerMiddle Oxfordian marls and limestones, as well as clasts from the uppermost Turonian-?Early Coniacian conglomerates of the Cracow Upland (southern Poland), reveal that the CL view of foraminifers from some lithologies differs from that in transmitted light. In particular, the CL technique revealed abundant tests of planktonic species Globuligerina oxfordiana in the Middle Oxfordian glauconitic marls, which under transmitted light are either poorly visible or remain completely undetected. Bright red-orange luminescence characterizes originally hyaline aragonitic tests of G. oxfordiana, but also several calcitic benthic species, in spite of their different taxonomic position and original test structure and mineralogy. In sponge microbial boundstones, foraminifers generally do not show the CL emission, or show a weak luminescence. Similarly, Late Cretaceous foraminifera represented mostly by planktonic taxa were detected or their view was clearly improved under CL only in some clasts from the uppermost Turonian-?Early Coniacian conglomerates filling karstic cavities. In other clasts, foraminifera are clearly visible only under normal transmitted light, therefore the luminescence signature is highly spatially variable. These results indicate a strong influence of lithology and diagenesis and rather minor effects of shell structure on luminescence of microfossils. The CL technique can be a useful tool in the detection and documentation of abundance patterns of foraminifers that are poorly preserved under transmitted light.

“…~10-20 ppm Mn 2+ concentration is necessary for visible Mn 2+ activated luminescence in biogenic calcite and the same or less in aragonite (Barbin 2000). In the case of pure carbonates or carbonates with minor traces of substituting element, a weak blue (so-called intrinsic) CL is detected for both polymorphs.…”

“…CL microscopy is a common technique in sedimentary petrology to study the mineralogy, texture and diagenetic history of carbonate rocks (Machel 2000). Biogenic carbonates (Barbin 2000) and fish otoliths (Halden et al 2004) are also routinely analysed.…”

Ontogenetic age and body dimensions were studied on three extremely well-preserved sciaenid fish otoliths from sublittoral marls of Lake Pannon from Doba, Bakony Mts, Hungary. Macroscopic and microscopic observations offered clear evidence for the preservation of the genuine structural characteristics, for instance the bipartite incremental features. Ontogenetic ages were assigned for the three specimens as 16, 7 and 6 years by counting the annuli of the sagittae. Analytical results prove that the original aragonitic mineralogy has been preserved making them, and probably other Late Miocene teleost fossils, suitable for future microchemical analysis to reconstruct the past physicochemical environment.
