Sulfide mineral layers are enclosed by and parallel to the sedimentary strata in which they occur. Most are diagenetic in origin Form when a hydrothermal solution invades and …

Sedimentary exhalative deposits Wikipedia

Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of orebearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.. SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten

What are zeolites? | How do zeolite catalysts work?

Mar 22, 2019· There are about 40 naturally occurring zeolites, forming in both volcanic and sedimentary rocks; according to the US Geological Survey, the most commonly mined forms include chabazite, clinoptilolite, and mordenite.

Zeolite Wikipedia

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
