Abstract
Field exploration work and analytic research on the Konya-Yunak sepiolite clearly revealed that the occurence was a result of the replacement of magnesite by sepiolite mineral in the magnesite pebbles and fragments derived from the surrounding magnesite deposits, and transported to the Miocene sedimentary basin. The replacement process developed under alcaline conditions bearing sufficient silica. Along with the pebbles composed wholly of magnesite or sepiolite, there also occur pebbles composed of both minerals in a crystalline mixture. But even sepiolitic concretions still preserve more or less the primary physical properties of magnesite. Serpentine minerals, dolomite and calcite have not entered into the formation reactions. Excess silica has precipitated as nodules or veinlets. On the other hand, matrix of the meerschaum consists mostly of the mineral palygorskite, which generate under almost the same contitions, except of a higher Al3+ ion concentration.
