EGQSJ - MiGIS: micromorphological soil and sediment thin section ...
网页2024年1月26日 · Micromorphological analysis using a petrographic microscope is one of the conventional methods to characterise microfacies in rocks (sediments) and soils. This analysis of the composition and structure observed in thin sections (TSs) yields seminal, but primarily qualitative, insights into their formation.
Observation of Soils: From the Field to the Microscope
网页2021年8月13日 · Micromorphology enters the soil investigations at the multi-centimetre scale (see “ File 3 ”) at which the thin section is made. The scales of observation span from the millimetre to the micrometre, and even down to the nanometre using electron microscopy (see “ File 7 ” and “ File 8 ”).
Examples of microstructures in thin section samples from the …
网页A record of brittle strain occurs in thin sections that contain edge-to-edge crushed grains in the form of grain fractures, microcracks, or grain flakes (Fig. 9).

Soil Micromorphology - SpringerLink
网页2020年1月14日 · The thin section technique is commonly used in direct evaluation of soil structure in situ under the microscope. Soils observed under a microscope reveal many pedological features which are not visible with the naked eye. This chapter explores the kinds of information that soil micromorphology can advance for the better understanding of …
The edge segmentation of grains in thin-section petrographic …
网页2023年8月26日 · Heilbronner et al. proposed a method for creating grain boundary maps from petrographic thin sections called lazy grain boundary (LGB). It extracts boundaries using gradient filtering on sets of regular polarized micrographs and combining the most significant grain boundaries on each image in a given input set to …
Comprehensive comparison and applications of different sections …
网页2020年2月1日 · Thick sections of developing kernels prepared by free-hand and sliding microtome-aided sectioning method can be employed to elucidate tissue anatomy and histochemistry. The thin sections of mature kernels prepared by ultramicrotome-aided sectioning method can exhibit the micromorphology of starch granules when stained with …
Guidelines for Analysis and Description of Soil and Regolith Thin ...
网页2003年1月1日 · George Stoops, a world expert on thin section analysis, presents the most up-to-date system of analysis and description of soil and regolith materials as seen in thin sections. Scientists and students from archaeology to pedology will appreciate the introduction of micromorphology, the thorough treatment of all …
Description of soil thin sections: An international comparison
网页1985年4月1日 · Seven thin sections were described by seven experienced micromorphologists independently using the new Handbook for Soil Thin Section Description. The sections were from soil horizons representing a range of soil materials formed by a variety of pedogenic processes.
