Presence and origin of volatile terpenes in succinite

Phytochemistry, 1980
Abstract The composition of the volatile fraction of four pine resins has been studied before and after an ‘ageing’ process. Typical terpenes of Baltic Amber were detectable after this ‘ageing’ process.

The natural product biomarkers in succinite, glessite and stantienite ambers from Bitterfeld, Germany

Review of Palaeobotany and Palynology, 2006
Abstract The biomarker compositions of six ambers (two glessites, two succinites, goitschite, and stantienite) from the Upper Oligocene of the Bitterfeld deposit in Germany were analyzed by gas chromatography–mass spectrometry (GC-MS) to determine their botanical origin.

Mid-infrared spectroscopy for characterization of Baltic amber (succinite)

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2018
Natural Baltic amber (succinite) is the most appreciated fossil resin of the rich cultural traditions dating back to prehistoric times. Its unequivocal identification is extremely important in many branches of science and trades including archeology, paleontology, chemistry and finally mineralogical and gemological societies.
