Tuff (in terms of Tephra)greenspun.com : LUSENET : Introductory Geology, Oswego State : One Thread
Is tuff made up of any specific (or any specific combination of) tephra size(s)? Or is tuff made up of any and all of types of tephra (ash, cinders, bombs)?

I would say that it can be made of all types of pyroclastic debris that have been molded together by heat.
