The Boxian meteorite (LL3-4), fallen in October 1977, possesses low degree of thermal metamorphism and good chondrule texture. A Ca-Al-rich chondrule (CA chondrule) was found in this chondrite. This chondrule is ca. 0.36 mm in diame ter. There is only one light red euhedral spinel crystal, ca. 34% in volume of this chondrule, while prismatic fassaite crystals occupy ca. 29% and only one small crystal of olivine and light brown intergranular glass of the above minerals, ca. 37% (Fig. 1).
