Abstract

Abstract Image processing techniques, including the Analyze Particles tool offered by Fiji software and the Intensity Profile by ICY (IP-ICY), were applied in core and outcrop examples to improve characterization of autocomposite ichnofabrics. Analyze Particles gives information about particle shape and size in the studied image. This tool was applied to Chondrites assemblages in composite ichnofabrics in view of selected images of modern marine hemipelagic cores from Site U1385 of IODP Expedition 339. Differences in size, relative abundance, density and distribution of Chondrites were interpreted as related to variations within the population of Chondrites tracemakers. Intensity Profile quantifies pixel values of the infilling material of traces, proving helpful to discriminate between specimens, evaluate the horizon of colonization, and approach the penetration depth. Its application to the analysis of Zoophycos improves characterization of composite ichnofabrics from deep-sea pelagic calcilutites of the Petra Tou Romiou section (Eocene Lefkara Formation; southern Cyprus). Some suites of Zoophycos were interpreted as associated with different phases of colonization from several horizons. Moreover, it was possible to discriminate structures pertaining to different specimens, as opposed to those from the same specimen.

改善复合技术织物特性的图像处理技术

采用斐济软件提供的Analyze Particles工具和ICY (IP-ICY)提供的强度剖面(Intensity Profile)等图像处理技术，对岩心和露头样品进行了分析，以改善自动复合技术织物的表征。Analyze Particles给出了所研究图像中有关颗粒形状和大小的信息。根据IODP 339考察队U1385站点的现代海洋半深海岩芯的选定图像，将该工具应用于复合技术织物中的球粒陨石组合。球粒陨石的大小、相对丰度、密度和分布的差异被解释为与球粒陨石示踪器种群的变化有关。强度剖面量化了痕迹填充材料的像素值，有助于区分标本、评估定殖水平和接近穿透深度。将其应用于动物藻类的分析，提高了Petra Tou Romiou剖面(始新世Lefkara组)深海中上层钙质复合技术织物的表征;塞浦路斯南部)。一些植藻组被解释为与不同阶段的殖民化有关。此外，可以区分属于不同标本的结构，而不是来自同一标本的结构。

期刊介绍： The foremost aim of Ichnos is to promote excellence in ichnologic research. Primary emphases center upon the ethologic and ecologic significance of tracemaking organisms; organism-substrate interrelationships; and the role of biogenic processes in environmental reconstruction, sediment dynamics, sequence or event stratigraphy, biogeochemistry, and sedimentary diagenesis. Each contribution rests upon a firm taxonomic foundation, although papers dealing solely with systematics and nomenclature may have less priority than those dealing with conceptual and interpretive aspects of ichnology. Contributions from biologists and geologists are equally welcome. The format for Ichnos is designed to accommodate several types of manuscripts, including Research Articles (comprehensive articles dealing with original, fundamental research in ichnology), and Short Communications (short, succinct papers treating certain aspects of the history of ichnology, book reviews, news and notes, or invited comments dealing with current or contentious issues). The large page size and two-column format lend flexibility to the design of tables and illustrations. Thorough but timely reviews and rapid publication of manuscripts are integral parts of the process.
