Abstract
The results of studies of Electronic Microscope (SEM) on the samples which came out of the autoclave, which has been under hydrothermal conditions (200 degrees centigrade and for 120 hours), show changes in structures of samples and create new crystallization system and Cancrinite Zeolit mineral synthesis, analsyme and merlinoit.The orientation of this research was Damavand Zeolite Zone with Eocene Age, located in Karaj, Sazand and was diagnosed with sedimentary genes. Measures, such as selective sampling of Zeolit minerals and XRF & XRD (broken samples), analysis and supplying thin pieces and preparing samples, washing with KOH & NaOH & Ammonia liquids, using magnetic stirring machines, autoclave, furnace and drier, and creating hydrothermal condition was done and finally, with electronic microscope and variable magnification, we watch an amount of synthesized crystals without breaking them, in order to picturing the crystals, type and form of them and point analysis via ED X-ray to elemental analysis. The results of the studies shows confirmation of changes to accomplished phase from natural Zeolit of Damavand  and synthesis of Zeolit minerals that considering using changes of natural Zeolit structure of Damavand  and synthesis of new minerals, with 70 years artificial Zeolits synthesis in labs, as a technical and economical justification for an international research, is very important.
