| Introduction
We investigated two processes in a series of the Hungarian L-chondrites: shock and
thermal metamorphism. Thermal metamorphism transforms the textures in the relatively
small chondritic planetary body. Shock metamorphism is caused by hypervelocity impact
processes transforming texture and mineral structure mainly in the outermost layers of the
chondritic planetary body [1,2]. The purpose of this optical microscopic study is to
indentify the degree of thermal metamorphism and stages of shock metamorphism
in the selected Hungarian meteorites, which have not been described well, up to
date.
Samples and Experimental Procedure
The mineral assemblages and textures were characterized with a Nikon Eclipse
LV100POL optical microscope using plane-and cross polarized light modes (at E |
