“…The strongest features are represented by the bands at 1609 cm −1 corresponding to the stretching vibrations of -C C-units in aromatic polycyclic system [26] . Compared to the analysis by the bench instrument, the band at 1576 cm −1 is recognised as a shoulder of the strong band at 1606 cm −1 which is probably due to poorer spectral resolution of the miniaturised spectrometer.…”

Raman spectral signatures have been obtained for a series of organic minerals using a compact portable Raman instrument equipped with 785-nm laser excitation. Well-resolved Raman spectra of crystalline salts of carboxylic acids, whewellite and mellite, as well as of the aromatic mineral idrialite were recorded. For comparative purposes, an amorphous fossil resin, baltic amber, was also investigated. The results obtained confirm that portable Raman instruments can be considered as excellent tools for field geological applications, including the detection of organic minerals in the frame of outcrops of sedimentary rocks or coal beds. Organic minerals can be added to the list of established biomarkers, including porphyrins, hydrocarbons and organic acids, which are important for the study with regard to future exobiological missions such as the ESA ExoMars mission to detect the presence of extinct or extant life on Mars.

Organic minerals are natural organic compounds with both a well-defined chemical composition and crystallographic properties; their occurrences reveal traces of the high concentration of certain organic compounds in natural environments. Thus the origin and process of formation of organic minerals will lead us to understand the fate and behavior of the organic molecules in the lithosphere. With the aim of their contribution to new developments in mineralogy, we subdivide organic minerals into two groups: (1) ionic organic minerals, in which organic anions and various cations are held together by ionic bonds, and (2) molecular organic minerals, in which electroneutral organic molecules are bonded by weak intermolecular interactions. This review is composed of four sections. The first section is concerned with the definition of both organic minerals and the above two groups. The second deals with crystal chemistry and geochemistry of oxalate minerals, which are the most typical ionic organic minerals. In this section, the role of (H 2 O) 0 is first discussed, as most oxalate minerals incorporate (H 2 O) 0 into their crystal structures. Then the phase relationships among hydrous and anhydrous calcium oxalate minerals, namely their structural hierarchy, are described, owing to the fact that they are the most abundant ionic organic minerals. In addition, the weak Jahn-Teller effect of the Fe 2+ ion is exemplified in humboldtine [Fe 2+ (C 2 O 4 )•2H 2 O]. The Fe 2+ ion causes distortions of octahedra in this organic mineral, though the effect has hardly been observed in inorganic minerals. In the third section, we describe the crystal chemistry and process of formation of polycyclic aromatic hydrocarbon (PAH) minerals, which are the most typical molecular organic minerals. Those of karpatite (C 24 H 12 ) and idrialite (C 22 H 14 ) are particularly considered in detail. In the fourth section, we summarize the characteristics of organic minerals and discuss their contribution to Earth and planetary sciences.Les minéraux organiques sont des composés organiques naturels ayant à la fois une composition chimique et des propriétés cristallographiques bien définies. Leurs présence témoigne de la concentration élevée de certains composés organiques dans les milieux naturels. Donc, l'origine et les processus de formation des minéraux organiques nous permettront de comprendre le sort et le comportement de molécules organiques dans la lithosphère. Dans le but de contribuer à l'essor de nouveaux développements en minéralogie, nous divisons les minéraux organiques en deux groupes: (1) minéraux organiques ioniques, dans lesquels les anions organiques et divers cations sont liés par des liaisons ioniques, et (2) minéraux organiques moléculaires, dans lesquels §

“…However, this type of spectroscopy in the study of amber is less common in contrast to IR spectroscopy. In general, vibrational spectroscopy (FTIR and Raman) is generally used to determine the complex aromatic components [ 35 ] as well as the molecular vibrations that make up the molecular framework of natural resin [ 30 ].…”

The article describes the results of Raman spectroscopy and SERS for the study of fluorescent components of Baltic amber via the extraction method. Using SERS, it was possible to confirm the presence of anthracene derivatives in amber: tetracene and benzanthracene. It has been shown that SERS methods are effective for the detection of aromatic compounds; they increase the registered Raman signal and make it possible to identify peaks characteristic of the compounds under study. By combining experimental methods with DFT simulations, anthracene derivatives were modeled and confirmed to be present in the structure of Baltic amber. A combination of the proposed methods can be used to distinguish between different types of amber and isolate the necessary amber components. The obtained results are promising for compiling spectral maps of ambers for their possible classification by their place of origin.
