Preparation and method of study of fossil diatoms
Abstract
Two methods of chemical concentration of diatoms occurring in fresh-water sediments, and one chemico-mechanical method of concentration for diatoms occurring in marine sediments are outlined, with emphasis on the extreme care that needs to be exercised during the preparation of the samples A method for the preparation of strewn slides is then explained A detailed procedure for the study of diatom-strewn slides under the microscope, using the "England finder", is described, and a note on diatom analysis is added
