Opis:
Infrared absorption spectroscopy was introduced at the Museum of the Earth of the Polish Academy of Sciences in Warsaw in 1985for research on fossil and subfossil resins of the world. As new reports on previously unknown findings have been made, a collection of resins from across the world has been developed according to the identifications based on the preliminary IRS method, documented by a catalogue of about 1200IR spectra, of which 344 are presented in the published ATLAS. The results of research, conducted with the participation of various teams, are presented. These include very useful activities that organize the terminology to protect against counterfeiting, and indications of the areas of differentiation of highly resin-producing forest communities, both in time and with regard to their migration over considerable distances. In search for the source tree of succinite, Pseu- dolarix vehri has been indicated based on both the IR spectra from Axel Heiberg (Canada) and the Paleogene paleogeography. In the studies of Indonesian glessites, the hypothesis of the contribution of volcanic processes to increased production of resin by trees has been proved. In amber (= succinite) with a solidfoam structure, SEM investigations revealed the presence of succinellite microcrystals (= succinic acid), hitherto known only as one of the components of dry distillation of the Baltic amber.

Opis:
The paper presents some problems in the studies on Baltic amber (succinite) and other fossil resins. Natural resins form a large group of fossils already known from various parts of the world. However, they markedly differ in age and origin which creates problems in their systematic nomenclature. At the beginning of this paper some definitions are presented concerning the scientific nomenclature of fossil resins as well as practical terminology. The fossil resins are the objects of interest of many scientific domains, especially as they are used for many purposes. The resins are investigated by scientists representing various natural sciences as well as archeologists and representatives of other disciplines; and in the aspect of application they are widely used in jewelry making as well as in some branches of industry (e.g. chemical and pharmaceutical). Variability of fossil resins along with complexity of their structure and composition, and broad issues of genesis and various historical aspects form a vast field of for further studies. However, the studies require the use of a multilateral approach, including instrumental analysis. The paper presents several examples of selected physicochemical methods which should be highly useful in solving questions concerning origin and composition as well as properties of fossil resins.
