Microfossil Sample Contamination and Reliability Problems

  • Owen R. Green


There are two aspects of processing micropalaeontological samples that have to be considered when interpreting and evaluating the fauna within the residue. Firstly, the effects of mechanical and chemical techniques employed during collection, disaggregation, maceration and residue dispersal must be eliminated. Secondly, sample reliability in reflecting a fauna contemporaneous with the time of deposition must be assessed. Discussions of the effects of sample processing can be found in other sections (see sections 14 DISAGGREGATION AND DISPERSAL OF PARTIALLY CONSOLIDATED AND UNCONSOLIDATED SEDIMENTS, 16 WASHING AND SIEVING TECHNIQUES USED IN MICROPALAEONTOLOGY and 17 CENTRIFUGE TECHNIQUES USED IN MICROPALAEONTOLOGY), and will only briefly be outlined here.
