Van Schmus (1967) called the main mass of Mezo-Madaras "normal", since he found three types of chondritic inclusions in the host material. Thus, there is a wide variety of chondrite in the main mass with the presence of porphyritic, radiant, barred and glassy textures. Olivine and pyroxene predominate in the chondrules. Pyroxene is typically a polysynthetically twin clinoenstatite with a low calcium content compared to clinohyperthene. Normal igneous zoning (Fe-poor centers and Mg-poor edges) is common in olivine and pyroxene crystals and, undoubtedly, represents the crystallization of these unequilibrated minerals during crystallization of the chondrules. The interstitial material of olivine and pyroxene in most chondrules consists of very fine-grained fibrous crystals, presumably olivine, pyroxene and plagioclase; this material probably represents the fibrous devitrification or crystallization of the residual melts that resulted in the chondrules during cooling and crystallization. Most of the metal and sulfide in this chondrite occurs outside the silicate cores as particles in the matrix or as droplets of metal sulfide. Metal and sulphide are generally mixed together. The Mezo-Madaras matrix includes fine-grained silicates (less than 10 microns in diameter), metal and sulfide. Source: Van Schmus (1967).
