A large number of microspherolites selected from Ningxiang lamproite, Hunan Pro- vince, South China, were examined and analysed by several approaches. In terms of their physical properties and chemical compositions, three groups of microspherolites can be distinguished. They are considered as volcanic microspherolites although those from sedimentary rocks and ocean floor are traditionally attributed to cosmic dusts. The microspherolites are described as of the following three groups:(1)nonmag- netic group, which is colorless and transparent, pale-yellow and semitransparent to dark yellow and opaque; (2) magnetic group, which is dark in color; (3)strong magnetic group, which is steel grey and dominated by iron. In addition, some volcanic dusts,such as magmatic splashed fragments and blocks, can also be observed. The features of microspherolites are varied, and their facies and textures show evidently that they are products of volcanism. Chemical compositions of these microspherolites vary in a wide range, from iron deficiency to iron dominance: (I)Fe-poor type, which is rich in Si, Mg, Ca and P,but poor in Ti, Mn and K; (2) Fe-rich type, which is high in Si, Ti, Mn and K,but poor in Ca, Mg and P; (3) Fe-high type, which is dominated by Fe. Lamproite microspherolites are characterized by diversity both in chemical composilion and in physical properties. It is concluded that liquation took place in the magma chamber after the emplacement of lamproite magma in the deep crust, and afterwards microspherolites were formed as a result of rapid cooling and quenching during volcanic eruption.
