Fluid inclusions in celestine and their significance in the study of the formation of the native sulphur deposits in the Carpathian Foredeep Open
Celestine is a rather common mineral in epigenetic native sulphur deposits and seems to be a very valuable indicator of some of the geological processes forming these deposits. This paper presents the results of investigation of fluid incl…

Stressed Atoms and Their Recover. Charge Density Redistribution With Pressure in a Zeolite Framework Open
As a result of external stress applied to crystals, ions relax, in addition to shortening the bond lengths, by changing their shape and volume. Modern mineralogy is founded on spherical ions/atoms, i.e. the close packing of spheres, ionic/…
