The properties of these rocks significantly influence the delivery of water that supply the raw ingredients for speleothem growth, and hence our focus in this article on dripwater hydrology. Carbonate sediments are converted to rocks by sets of diagenetic processes in marine, meteoric , or burial environments. Home Contact Imprint Sitemap Webmail.

Philosophers differ on how an event is defined, but for cultural history, it can be taken as a change in some entity: the addition, subtraction, or transformation of parts. Events can be considered at two scales. At the scale of individual object, the event is either manufacture which, e.
