Flysch et molasse

Abstract

Petrographic and geologic observations on the Flysch deposits of the French and Swiss Alps, the Romanian Carpathians, the northern Apennines (Italy), and the French and Spanish Pyrenees show that there are two distinct groups of formations. The first group consists of true Flysch deposits, but deposits of the second group are comparable to marine molasse beds. The petrographic and geologic characteristics of the two types are compared in a table, and examples of each are given.
