Abstract

Opals with inclusions of plant fossils are presented among the kaolin of weathering crusts of the Ukrainian Shield. They have a form like fiber and thread "tubes" with the maximal visible length in the order of 4-5 meters.  The elements of the conduction system in some transverse sections have been observed. During the erosion of weathering crust puddles with the colloid solution silicic acid were formed. Fragments of plants getting there became centers of the opal’s mineralization
