Pelagosite

from Wikipedia, the free encyclopedia

Pelagosit (after the island Palagruža , Italian: Pelagosa , Adria ) designates a carbonatic sinter formation , which was first discovered by Carlo de Marchesetti in 1876 and described in Tschermak's Mineralogical and Petrographic Notes in 1878 and in 1882/83 by Marchesetti , which in the splash water area of ​​subtropical and tropical sea coasts creates a hard, shiny and black-colored coating forms over the rocks. The coating goes back to the crust-forming activity of cyanobacteria and consists mainly of pisolithic aragonite with a small proportion of foreign components, mostly of an organic nature.

The way of education was controversial for a long time. The work of Ettore Onorato from 1926 played a major role in the exploration of pelagosite. A current work comes from Montanari and others (2007), who see in the detailed study of such crusts the possibility of the climate of the past and the uplift or Reconstruct subsidence history of the Mediterranean islands.
