The overview of analytical methods for studying of fossil natural resins
Critical Reviews in Analytical Chemistry, 2023The review presents methods that are used frequently for multi-analytical study of fossil resins. The preliminary characterization relies on physical methods such as microhardness, density and fluorescence in UV light measurements. The spectroscopic methods: infrared spectroscopy, Raman spectroscopy, fluorescence spectroscopy are also presented in the ...

Fossil resins of Alaska: history of study
Vestnik of geosciences, 2023The article reviewes the current state of knowledge of fossil resin finds in Alaska (USA). On the basis of little-known and fragmentary documents found in both Russian and foreign scientific literature, their main locations are briefly described. The primacy of Russian researchers mentioning fossil resins of coastal regions of Alaska is noted.

Arthropods in contemporary and some fossil resins
Paleontological Journal, 2009More than 4800 arthropod inclusions were isolated and identified from resin of various contemporary conifer trees in various parts of northern Eurasia. Their composition is compared with that in representative collections of Baltic and Rovno ambers (Upper Eocene) and with that in Dominican amber (Lower Miocene).

Duxite – Fossil resin of Miocene age
Organic Geochemistry, 2018Abstract A series of Miocene fossil resin from the northwest part of the Czech Republic, called duxite, has been analyzed by elemental, microscopic, gas chromatography (GC/MS), pyrolysis-gas chromatography, Fourier Transform infrared (FTIR), and Raman techniques.

Chemical Signatures of Fossilized Resins and Recent Plant Exudates
Angewandte Chemie International Edition, 2008AbstractAmber is one of the few gemstones based on an organic structure. Found over most of the world, it is the fossil form of sticky plant exudates called resins. Investigation of amber by modern analytical techniques provides structural information and insight into the identity of the ancient plants that produced the source resin. Mass spectrometric

Kauri Resins—Modern and Fossil
1969The genus Agathis, a group of conifers found in the land areas between New Zealand and Malaysia, has several conspicuous resin-forming systems. Thus, the New Zealand species Agathis australis (Salisbury) produces resins, often in very large amount, in the heartwood, in resin canals in the bark, in resin canals in the leaves, in the leaf surface layers,

A Raman spectroscopic approach to the maturation process of fossil resins
Journal of Raman Spectroscopy, 2001Raman spectra of a range of differently aged samples of natural resins (recent resins, copals, fossils resins from Tertiary to Early Cretaceous age) were taken for a comparative study of the age-induced maturation processes of the resins. It can be shown that a decrease in band intensity at around 1640 cm−1 due to loss of ν(CC) stretching vibrations ...

Occurrence of Fossil Resins in the Oil-Shales of the Punjab Saline Series
Nature, 1950IN a recent discussion1 on the age of the Saline series, Dr. E. R. Gee disputes Prof. B. Sahni's evidence of micro-fossils for an Eocene age2 on two grounds: first, the discovery by Messrs. Ghosh, Sen and Bose3 of similar post-Palaeozoic micro-fossils in overlying beds of undoubted Cambrian age shows that Prof. B.

Varieties of fossil resins of South Sakhalin and their molecular composition
Zapiski Vserossijskogo mineralogičeskogo obŝestvaThis article provides the first up-to-date overview of the history of fossil resin finds in the southern part of Sakhalin Island. On the base of little-known facts and casual references scattered in geological literature, main locations of the amber-like fossil resins are reviewed and described. Peculiarities of their molecular composition were studied,
