在南非Vredefort构造周围的领状岩石中，一些破碎锥的表面上出现了硅酸盐成分的球形颗粒。它们最好在页岩层的破碎锥上发育，但也可在砂质岩石和带状铁矿石上发现。在较纯的石英岩的震锥上还没有发现它们。
Spherical particles of silicate composition occur on the surface of some shatter cones from the collar rocks around the Vredefort structure, South Africa. They are best developed on shatter cones from a shale horizon but are also found on more arenaceous rocks and banded ironstones. They have not been found on shatter cones from the purer quartzites.
