How natural zeolites form and deposit

Nowadays, one of the most important questions is: How natural zeolites are formed and their zones are identified? According to geological exploration studies, the genesis and origin of zeolite deposits in salt lakes and brackish water are alteration and erosion of volcanic rocks and tuffs, soils with alkaline environments (of saline origin). In salt lakes and brackish water (which can be paragenesis with rare earth elements), usually in areas with hot and dry climatic conditions and in a part of the water with acidity whose pH reaches about ۹.۵, a suitable environment for the formation of zeolite deposits. Based on the results of field visits and observations in the Sadr al-Dhikr areas, the following minerals, including tuffs, obsidian or natural glass, kaolin or porcelain clay, and rhenium minerals such as montmorillonite, are converted into zeolite in the aforementioned lakes. Of course, the existing minerals are considered as a guide for the exploration of zeolite deposits. Zeolite deposits are also formed by the influence of many hydrothermal solutions, and in this regard, clino and mordenite zeolites are formed at depths and at lower temperatures, and zeolites such as hyalandite and lamontite are formed at greater depths and at higher temperatures. Zeolite deposits are classified into two types, volcanic and sedimentary, based on the conditions of formation and genesis. Zeolite deposits are found in most volcanic rocks, and usually in these rocks, zeolites are outcropped as primary and secondary minerals.
