Zeolites have been used in agriculture since the 1960s, due to effectiveness of these crystalline microporous solids as soil amendments for plant growth, their cation exchange capacity (CEC) and slow-release fertilizer properties. Most work on fertilizers has focused natural Clinoptilolite, Phillipsite Chabazite. The aim this study was synthesize clinoptilolite type zeolite-enriched amendments....

A new locality of zeolite minerals occurs on the NE edge Jedlka village, at SE slope Hlídka hill, 2 km to W Benešov nad Ploučnicí (northern Bohemia, Czech Republic). The mineralization is developed in Cenozoic analcime-nepheline tephrite. Ten mineral species (gmelinite-K, analcime, harmotome, chabazite-Ca, lévyne-Ca, mezolite, natrolite, offretite, phillipsite-K, thomsonite-Ca) were found small...

The weathering of primary silicates, and their carbonation in particular, is key for the geochemical cycling elements, strongly affecting C cycle long-term regulation Earth's climate. knowledge on controlling factors mechanisms aqueous silicates however still far from complete. This precludes a better understanding chemical nature strong handicap to implement effective Carbon Capture Storage (C...

[1] Jarosite occurs within altered tephra from the saline‐alkaline paleolake deposits of Pliocene‐Pleistocene Olduvai Gorge, Tanzania. Zeolites (mainly phillipsite), authigenic K‐feldspar, and Mg/Fe‐smectites dominate the mineral assemblage, indicating saline‐ alkaline diagenetic conditions (pH > 9). As jarosite is ordinarily an indicator of acidic conditions on Earth and Mars, its association ...
