Sedimentary Environments in a Marine Marsh [PDF]

open access: possibleScience, 1966
Several foraminiferal assemblages are recognized in Spartina-Salicornia marshes along the Pacific and Gulf of Mexico coasts. Continuous recordings in one Pacific marsh show considerable diurnal and seasonal variation in p H, oxygen, water temperature, and salinity.

Sedimentary environment in Taiwan Shoal

Chinese Journal of Oceanology and Limnology, 1992
Taiwan Shoal sediments are well sorted and rounded medium-coarse sands containing a large amount of shell and beach rock fragments and basalt gravels, and are of deltaic, coastal and colian origin. Underwater sand waves are formed by the combined tidal currents and are remolded by storm waves.

Sedimentary Environment in the Taiwan Shoal

Marine Georesources & Geotechnology, 2003
The Taiwan shoal sediments are well sorted, rounded, medium-coarse sands containing a large amount of shell and beach rock fragments and basalt gravels of deltaic, coastal, and aeolian origin. Underwater sand waves are formed by the combined tidal currents and remolded by storm waves.

Tide-influenced sedimentary environments and facies

Marine Geology, 1988
This volume contains examples of recent as well as fossil tide-influenced sedimentary facies. Studies of recent tidal processes and sediments provide an insight into the way in which tidal facies and sequences develop, and into the processes which are active.

Monitoring the sedimentary carbon in an artificially disturbed deep-sea sedimentary environment

Environmental Monitoring and Assessment, 2011
An area of 0.6 km(2) in the manganese nodule field of the Central Indian Basin was physically disturbed and sediments discharged in the near bottom waters to simulate seabed mining and study its impact on benthic ecosystem. An estimated 2 to 3 tonnes of sedimentary organic carbon (C(org)) was resuspended into the water column during a 9-day experiment.

Classification of Sedimentary Environments: ABSTRACT

AAPG Bulletin, 1969
Geologic literature contains material from which a variety of working classifications of sedimentary environments may be constructed according to the geologist's need. The range of approaches to environmental classification is evident in the use of terms derived from places of deposition, processes and media of deposition, and materials deposited. Much

Recognition of Ancient Sedimentary Environments

1972
Abstract This volume contains a series of papers presented as part of a symposium held in Dallas, Texas, April 1969, at the annual national meeting of the Society. The problem of recognizing ancient sedimentary environments in the stratigraphic record is basic to essentially every aspect of research in sedimentary rocks.

A New Geochemical Classification of Sedimentary Environments

SEPM Journal of Sedimentary Research, 1981
Because of the relative constancy of pH in most subaqueous sediments and the general lack of measurability of Eh, these parameters are not practically useful for classifying sedimentary environments. In their place a new classification is offered which, derived from studies of modern sediments, is based on the presence or absence of dissolved oxygen ...

Coal-Producing Sedimentary Environments

1992
Genetically related lithosomes constitute the integrated response of a sedimentary environment to the depositional process. Sedimentary environments are therefore integral parts of the hierarchy of sedimentation elements, since they consist of combinations of lower ranking sedimentation elements by which they can be identified.
