Abstract
Ultramicrotomy is the most suitable sample preparation technique for the study of mineralogy and petrology of fine-grained (<100μm across) rock fragments, such as interplanetary dust particles and unmelted micrometeorites, because we can observe wide areas(a few tens of μm across)by a transmission electron microscope (TEM). There are some difficulties to make ultrathin sections of meteorites and cosmic dusts. The difficulties are different from those to make ultrathin sections of biological samples. The author explained in detail the principle of ultramicrotomy, sample preparation procedures in the author's laboratory, variations of sample preparation techniques in other laboratories, and showed some examples of ultrathin sections of a meteorite and a interplanetary dust particle.
