Collection of samples for petrological, geochronological, geochemical, palaeontological, sedimentological and palaeomagnetic studies.

Here we describe geochemical and microbiological studies which suggest that contemporary formation of siderite concretions in a salt-marsh sediment results from the activity of sulphate-reducing bacteria.

Structural and geochemical studies are of the greatest value in the Northern Highlands.

It is suggested that there is scope for further geophysical and geochemical studies within the Midland Valley region.

Most deep sea research projects did not carry out geochemical and biological studies at the same lcoations.

Biological and geochemical studies were mostly carried out separately which seems to be a systematic, scientific pattern and poses a problem in deep sea research.

Complementary geochemical studies are under way.

The conservation area contains Crawford Lake, a meromictic lake, which makes the lake a prime site for archeological and geochemical studies.

The title of his thesis was "Petrological and geochemical studies in the Coronaca area, Greenwood County, South Carolina".

Diagenetic and geochemical studies are enhanced by the very fine CL resolution of growth histories in crystals (Fig. 6.4).
