“…General topics include for example (1) the identification of minerals, mineral distribution, and quantification, (2) visualization of primary and secondary microstructures (growth zoning, deformation features, fluid flow, etc. ), (3) crystal chemistry (trace element distribution, internal structures), (4) reconstruction of geological processes, and (5) characterization of technical products (Marshall, 1988; Barker & Kopp, 1991; Götze, 2000; Pagel et al, 2000; Gorobets & Rogozine, 2002; Gaft et al, 2005; Boggs & Krinsley, 2006; Gucsik, 2009).…”

“…The successful applications of CL are given in several textbooks dealing with the application of luminescence techniques in geosciences starting with the fundamental works of Marfunin in the 1970s (Marfunin, 1979). Several further publications emphasized the role of CL as a powerful technique applied to minerals and rocks (e.g., Marshall, 1988; Barker & Kopp, 1991; Götze, 2000; Pagel et al, 2000; Gorobets & Rogozine, 2002; Nasdala et al, 2004; Gaft et al, 2005; Boggs & Krinsley, 2006; Gucsik, 2009).…”

Cathodoluminescence (CL) microscopy and spectroscopy are luminescence techniques with widespread applications in geosciences. Many rock-forming and accessory minerals show CL characteristics, which can be successfully used in geoscientific research. One of the most spectacular applications is the visualization of growth textures and other internal structures that are not discernable with other analytical techniques. In addition, information from CL imaging and spectroscopy can be used for the reconstruction of processes of mineral formation and alteration to provide information about the real structure of minerals and materials, and to prove the presence and type of lattice incorporation of several trace elements. In the present article, an overview about CL properties of selected minerals is given, and several examples of applications discussed. The presented data illustrate that best results are achieved when luminescence studies are performed under standardized conditions and combined with other analytical techniques with high sensitivity and high spatial resolution.

“…CL was also utilized to determine if the internal structure of the rock framework differed in the pre-CO 2 versus the post-CO 2 cores. CL can provide the basis for understanding the origin, diagenesis and porosity development that can occur in carbonate rocks (Marshall 1988;Barker and Kopp 1991;Pagel et al 2000). CL can distinguish the carbonate phases, cement growth on pre-existing crystals as well as porosity evolution; such petrographic analysis can aid in understanding if different conditions were present in the formation and diagenesis of carbonate reservoirs (Hiatt and Pufahl, 2014).…”

“…CL, defined as the emission of light from a sample during electron bombardment, is a technique that has been used to study trace-element chemistry and zoning in minerals such as calcite (Paquette and Reeder 1990;Reeder 1991), dolomite (Searle 1990;Fouke and Reeder 1992); zircon (Hanchar and Rudnick 1995), apatite (Mariano 1988;Rakovan and Reeder 1994), diamond (Davies 1979), feldspar (Finch and Klein 1999;Goetz et al 1999), quartz (Zinkernagel 1978;Onasch and Venneman 1995), and many others. Furthermore, the combination of plane-light (PL) and CL petrography has proven to be an invaluable tool with which to interpret the depositional and diagenetic history of sedimentary rocks (Marshall 1988;Barker and Kopp 1991). It is in these studies of sedimentary minerals and rocks that CL has seen its widest application in the earth sciences.…”

Quantification of Bioturbation in Hemipelagic Sediments Via Thin-Section Image Analysis: RESEARCH METHODS PAPERS

Traditional ichnofabric-descriptive (semiquantitative) schemes rely upon subjective estimates of the degree to which original sedimentary fabrics have been disrupted. This paper presents an objective method of quantifying bioturbation in hemipelagic sediments based on a thin-section image-analysis technique. In order to perform these analyses, optical or backscattered electron micrographs are processed in order to obtain black and white images. In these images black pixels are silt-size, larger grains and the clay-size sedimentary matrix are white pixels. Once the initial processing has been accomplished, an index, H, is defined to quantify the horizontal orientation of the larger grain size fraction of the sediment. H is low for bioturbated fabric and high for laminated sediments. In hemipelagic suspension deposits, H can be used to quantify bioturbation, assuming that no other sedimentary processes have disrupted the original depositional fabric. The quantitative bioturbation scheme described here is consistent with existing semiquantitative bioturbation schemes; in addition, it is objective and provides higher-resolution descriptions of biological processes that disrupted the sediment after deposition. Applying this quantitative scheme should refine future paleoecological reconstruction derived from lacustrine and marine successions.
