Following the pioneering work of Goldschmidt and Peters (1932a, b), the geochemistry of
boron has been explored in intermittent bursts of activity, usually associated with …

Zeolites can originate from a variety of precursor materials including volcanic and impact
glasses, aluminosilicate gels, and aluminosilicate minerals including other zeolites …

Publisher Summary This chapter summarizes the sedimentary characteristics of non-marine
environments. Non-marine evaporite deposits are common features of modern arid closed …

A mid to late Tertiary lake, Palaeolake Etosha, was the single collective end point of three
drainage systems feeding southwards off the central Angolan highlands, the Cubango and …

Tuffaceous rocks and lavas of the Pliocene age exist on Kimolos Island, Aegean Sea,
Greece. These tuffaceous rocks have been locally transformed to clinoptilolite and …

This study describes and interprets the mineral and facies assemblages of lacustrine shales
that occurred in an ancient volcanic-related alkaline playa-lake, considering the importance …

Zeolites were first described from vugs and fissures in basaltic flows in the mideighteenth
century (Cronstedt 1756), and they are now known to be widespread in a variety of …

Résumé The morphometric analysis of alluvial drainage provides insights into its dynamics,
erosion capacity, susceptibility to floods and possible genetic relations to tectonic faulting. In …

The Miocene borate deposits of western Turkey are associated with extensive medium-to
high-K calc-alkali ignimbritic volcanism and a differentiated comagmatic alkaline …

Authigenic silicates are typical minerals of alkaline lake deposits. Their mineral composition
and lateral distribution can be used for reconstructing paleoclimates, paleoenvironments …
