Well-preserved fossil assemblages provide valuable insights into the evolutionary history of biota and their environments. Here, we report on Rupelian (early Oligocene) siliceous nanoeukaryotes from diatomites in the Carpathian Mountains, southeaster

Since the discovery of mesoporous silica in 1990s, there have been numerous mesoporous silica-based nanomaterials developed for catalytic applications, aiming at enhanced catalytic activity and stability. Recently, there have also been considerable i

Diatomites are sedimentary rocks rich in siliceous algae, mainly diatoms, and are evident in Greece mainly in Neogene successions. Despite their significance and worldwide potential as source rocks for hydrocarbons, little is known about them in the

The conditions of the formation of nonmetallic and ore minerals in limnogenic structures are considered. It has been established that lakes are natural enriches of a wide range of useful components - silicate, carbonate, water-soluble, ore, organomin

Fossil plant macroremains preserved in laminated diatomites from Łysa Góra near Rębiszów, Lower Silesia, have been documented for the first time. The fossil assemblage consists mostly of leaves, but fruits, seeds and sporadic flowers also occur.

Diatomites of the Paleocene-Eocene age are widespread in the Trans-Urals and act as soil-forming rocks in river valleys. At the same time the direction and nature of the processes of soil formation on such deposits are practically not studied. The pa
