Catalysis at mineral surfaces might generate replicating biopolymers from simple chemicals supplied by meteorites, volcanic gases, and photochemical gas reactions. Many ideas are implausible in detail because the proposed mineral surfaces strongly prefer water and other ionic species to organic ones. The molecular sieve silicalite (Union Carbide; = Al-free Mobil ZSM-5 zeolite) has a three-dimen...

Amphibolitic rocks are the main part of the north of Khoy metamorphic complex. Petrographicaly these rocks are normal amphibolite, muscovite amphibolite, biotite amphibolite, garnet amphibolite and pyroxene amphibolite. The protolith of these rocks is mainly igneous. These rocks belong to tholeiitic and calc-alkaline series and Ocean Floor Basalt and Arc tectonic setting. These two distinctive ...
