Taphonomy of Fossil Resins: A Petrological and Geochemical Approach Using the Van Krevelen Diagram
Fossil StudiesFossil resins from the area of Gulf of Gdańsk, Lublin area, Denmark, Bitterfeld, Lusatia and Ukraine, often grouped under the collective term ‘Baltic amber’, are complex organic mineraloids that have undergone various post-depositional transformations ...

Ichnotaxonomy of new boring taxa: linking insect activity and fossil resins formation
PalaeoentomologyThe fossil record reveals palaeoecological interactions between plants and insects. This study describes a singular conifer xylite specimen from the Baltic amber-bearing deposits, with preserved resin ducts and cylindrical insect borings designated as ...

Raman spectroscopy and SERS for determining the relative age of fossil resins
Laser physicsThis paper presents Raman data from studies on 27 fossil resin samples sourced from different geographical locations and representing various relative ages. Ages ranging from the Late Triassic (T3) to the modern period (Q4) were investigated. The primary

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.

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
