Abstract

In this study the new mineralogical and geochemical evidence for the reason behind intensive resin production in trees and the formation of Indonesian resin deposits is presented. The analysed specimens of the “Indonesian amber” were subjected to the following comprehensive investigations: PAS, IR, RS XRD and SEM-EDS. It was found that the resins are originated due to intensive volcanic activity. Based on spectroscopic investigations, “Indonesian amber” was assigned to the glessite group. The investigations revealed that the traces of volcanic activity have survived in the studied specimens in their structure were the presence of tonstein and inorganic minerals are related to volcanic phenomena. “Floating” in opaque solid–foam resin indicated that resinous substance was strongly heated trough volcanic activity.

“印度尼西亚琥珀”沉积物的分析特征:火山活动形成的证据

在这项研究中，提出了新的矿物学和地球化学证据，说明了在树木中密集生产树脂的原因和印度尼西亚树脂矿床的形成。对“印度尼西亚琥珀”的分析标本进行了PAS、IR、RS、XRD和SEM-EDS等综合研究。发现这些树脂是由于强烈的火山活动而产生的。根据光谱调查，“印度尼西亚琥珀”被分配到玻璃石组。研究结果表明，火山活动的痕迹在研究标本的结构中得以保存，其结构中存在着与火山现象有关的无机矿物。在不透明的固体泡沫树脂中“漂浮”表明树脂物质在火山活动中被强烈加热。

期刊介绍： BALTICA is an international periodical journal on Earth sciences devoted to the Baltic countries region and the Baltic Sea problems. This edition as a Yearbook is established in 1961 by initiative of Academician Vytautas Gudelis. Since 1993, an Editor-in-Chief of the journal became Academician Algimantas Grigelis. BALTICA is published biannually (in June and December) in cooperation with geoscientists of the circum-Baltic States. BALTICA is publishing original peer-reviewed papers of international interests on various Earth sciences issues. The particular emphasis is given to Quaternary geology, climate changes and development of ecosystems, palaeogeography, environmental geology, as well as stratigraphy, tectonics, sedimentology and surface processes with relevance to the geological history of the Baltic Sea and land areas. Journal emphasizes modern techniques, methodology and standards. The journal structure comprises original articles, short reviews, information, bibliography.
