摘要：

This 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 (T-3) to the modern period (Q(4)) were investigated. The primary method for estimating the age of the resins involved determining the ratio nu(C = C)/sigma(CH2), which was 1650-1600 cm(-1) and 1450 cm(-1 )respectively, making it possible to differentiate between fossil resins from T-3 and K(1 )and those from Q and Q(4). Surface-enhanced Raman spectroscopy, combined with machine learning algorithms, was used to further clarify the differences between the consecutive K-1 and K-2 ages
