Abstract

ABSTRACT The processing of subfossil wood poses some difficulties in densitometric research. Problems arise because of the physiochemical changes of wood occurring in the sedimentation environment. Subfossil wood modification can result from the uptake of mineral and organic substances into the wood tissue. It can also occur as the effect of microbiological degradation of wood. The goal of this study was to identify the appropriate method of subfossil wood preparation for the densitometric research. For this purpose the wood of Norway spruce from Lake Schwarzensee was subjected to extraction in de-ionized water, acetone and diluted acetic acid. The application of acetic acid did not significantly influence the density of the wood and acetone seemed to be too aggressive. The best result was obtained by rinsing the samples in cold de-ionized water. This extraction procedure allowed removal of unwanted water-soluble, organic and inorganic compounds from wood and simultaneously did not lead to the degradation of subfossil samples.

奥地利阿尔卑斯山挪威云杉亚化石木材的x射线密度测定。

亚化石木材的加工给密度测量研究带来了一些困难。木材在沉积环境中发生的理化变化引起了一些问题。亚化石木材的改性是由木材组织吸收矿物质和有机物引起的。它也可以发生的影响微生物降解木材。本研究的目的是为密度学研究确定合适的亚化石木材制备方法。为此，用去离子水、丙酮和稀释的醋酸对来自施瓦辛格湖的挪威云杉木材进行提取。醋酸对木材密度的影响不显著，而丙酮对木材密度的影响太大。用冷去离子水冲洗样品效果最好。这种提取过程可以从木材中去除不需要的水溶性、有机和无机化合物，同时不会导致亚化石样品的降解。

期刊介绍： Tree-Ring Research (TRR) is devoted to papers dealing with the growth rings of trees and the applications of tree-ring research in a wide variety of fields, including but not limited to archaeology, geology, ecology, hydrology, climatology, forestry, and botany. Papers involving research results, new techniques of data acquisition or analysis, and regional or subject-oriented reviews or syntheses are considered for publication. Scientific papers usually fall into two main categories. Articles should not exceed 5000 words, or approximately 20 double-spaced typewritten pages, including tables, references, and an abstract of 200 words or fewer. All manuscripts submitted as Articles are reviewed by at least two referees. Research Reports, which are usually reviewed by at least one outside referee, should not exceed 1500 words or include more than two figures. Research Reports address technical developments, describe well-documented but preliminary research results, or present findings for which the Article format is not appropriate. Book or monograph Reviews of 500 words or less are also considered. Other categories of papers are occasionally published. All papers are published only in English. Abstracts of the Articles or Reports may be printed in other languages if supplied by the author(s) with English translations.
