Введение. Представлены результаты исследований ископаемых смол различного геологического возраста и географического происхождения. Предложен новый метод спектрального анализа для дифференциации ископаемых смол по возрасту от триасового периода до современности, позволяющий спектрально отличить ископаемые смолы друг от друга. Впервые получены спектры комбинационного рассеяния света для ископаемой смолы позднего триасового периода. Показана возможность применения метода для дифференциации смол от позднего триасового периода до современности.

Метод

Метод. Исследования выполнены методом спектроскопии комбинационного рассеяния света. Спектры получены с использованием спектрометра Renishaw Virsa (Великобритания) для длины волны 785 нм и портативного спектрометра комбинационного рассеяния света Raport 1064 (Россия) для 1064 нм. Диапазон исследованных спектров 400–3200 см–1. Изучено 27 образцов ископаемых смол Евразии, Африки, Америки, Австралии.

Основные результаты

Основные результаты. По результатам исследований образцов ископаемых смол различного географического местоположения и возраста установлены различия в величинах отношения колебательных мод валентного скелетного колебания (ν(С=С)) и деформационного колебания группы СH2 (σ(СH2)) в диапазонах волновых чисел 1650–1600 см–1 и 1440–1460 см–1 соответственно у ископаемых смол в возрасте от триасового периода до современности. Установлено, что с увеличением возраста смолы, степень их полимеризации уменьшается. Для смолы возраста триасового периода показано отсутствие сигналов ν(СH2, СH3) в высокочастотной области для лабданового каркаса, что свидетельствует о крайне низкой степени полимеризации структуры.

Обсуждение

Обсуждение. Полученные результаты потенциально позволяют применять метод комбинационного рассеяния света для дополнительной дифференциации возраста ископаемых смол, в случае ограничения применения метода радиоуглеродного анализа по возрасту (40 000 лет). Преимуществом предложенного метода является возможность быстрого, с минимальной пробоподготовкой определения возраста ископаемой смолы возрастов триасового и раннего мелового периодов и современности. Вместе с точностью дифференциация возрастов ископаемых смол в диапазоне возрастов от позднего мелового периода до олигоценмиоцен пока остается низкой, что требует дополнительных исследований. Также на данном этапе развития метод не учитывает влияние условия окружающей среды: климата, растительности, условий фоссилизации, при которых происходили превращения живицы в смолу.

The results of studies of fossil resins of different geological ages and geographic origins are presented. A new method of spectral analysis for differentiation of fossil resins by age from the Triassic period to Modernity is developed. Raman spectra of fossil resin of the late Triassic period are obtained for the first time. The possibility of using the method for differentiation of resin from the late Triassic period to the Moderiny is shown. The studies were carried out using Raman spectroscopy. The spectra were obtained using a Renishaw Virsa spectrometer (UK) with an excitation wavelength of 785 nm and a Raport 1064 portable Raman spectrometer (Russia) with an excitation wavelength of 1064 nm. The range of the studied spectra was 400–3200 cm–1. 27 samples of fossil resins from Eurasia, Africa, America, and Australia were studied. Based on the results of studies of fossil resin samples from different geographic locations and ages, differences were found in the values of the ratio of vibrational modes of the valence skeletal vibrations (ν(C=C)) and the deformation vibration of the CH2 bond (σ(CH2)) in the wavenumber ranges of 1650–1600 cm–1 and 1440–1460 cm–1 in fossil resins aged from late Triassic to Modernity. It was found that with increasing age of amber, the degree of their polymerization decreases. For amber of age Triassic, the absence of ν(CH2,CH3) signals in the high-frequency region for the labdanum skeleton of the resin structure was shown, which indicates an extremely low degree of polymerization of it structure. The obtained results potentially allow using the Raman scattering method for additional differentiation of the age of fossil resins, in case of limitation of the application of the radiocarbon analysis method by age (40,000 years). The advantage of the proposed method is the possibility of rapid, with minimal sample preparation, determination of the age of fossil resin of ages Triassic, Cretaceous, Modernity. At the same time, the accuracy of differentiation of the ages of fossil resins in the age range from Cretaceous to Oligocene to Middle Miocene still remains low, which requires additional research. Also, at the current stage of development, the method does not take into account the influence of environmental conditions: climate, fossilization conditions under which the oleoresin was transformed into resin.
