Druze

**Introduction**

Drusen is an unusual natural phenomenon that can be observed in several places around the world. Druses are feldspar crystals that form small, slot-like cavities or cavities in sedimentary and igneous rocks. Such clusters of drusen have different sizes and shapes, and can also be painted in different colors - from white to dark green, sometimes red.

**The origin story of the Druze**

At the moment, scientists have not been able to accurately determine the causes of drusen formation. Accumulated experience and research indicate that there are several hypotheses about the origin of this phenomenon, but each of them remains controversial. Let's consider some of the hypotheses.

According to one of these versions, druses appear as a result of compaction of sedimentary rocks, where compression of the intercrystalline substance occurs. It is also believed that the formed drusen are the result of a reaction between minerals and water or liquids, including ore solutions. Some studies indicate that drusen formation may be associated with an increase in mineral solubility with changes in temperature and pressure. Another factor in the formation of drusen is a change in the chemical composition and acidity of rocks. Thus, an increase in rock alkalinity increases the solubility of minerals, including feldspar. An increase in rock carbonate content leads to faster growth of field crystals.
