The Environmental Significance of Conglomerates

W. H. Twenhofel

ABSTRACT

Gravels may be deposited under many conditions of environment and in themselves indicate only that some agent was competent to bring them to the places where they occur and that a source area was not too far distant whence they were derived. Certain features of gravel deposits, among which are imbrication and shapes of particles, cross-lamination, association with other sediments, and areal distribution, may indicate the environment in which deposition took place. Some features of gravels, among which is degree of rounding, may have been inherited from some earlier environment.
