Aspects of the chemical and microscopic characteristics of plant ashes ...
网页2003年12月30日 · 2. Ash micromorphology. Fresh ash found in the field is usually a mix of fully or partially oxidised plant tissues and soil. Along with the plant residues, therefore, ash may contain quartz grains, burnt soil carbonates, charcoal and soil aggregates.
Soil Micromorphology - SpringerLink
网页2016年1月1日 · Soil micromorphology is the microscopic study of the soil, and since it usually employs the use of petrographic thin sections, it is similar to the geological discipline of petrography. The basic analytical equipment of soil micromorphology is the petrographic or polarized light microscope.

Soil Micromorphology: Concepts, Techniques, and Applications
网页2008年4月15日 · Micromorphology is now an established analytical tool that provides unique information for any discipline where soil particles, pores, and organisms play a role. It can be used simply as a descriptive tool, or as a quantitative one when descriptions are backed by morphological measurements or chemical and mineralogical analyses.
