The details of the physical characteristics will have relevance when correlated with the pollen and microfossil analysis.
Not all lakes possess sediment records that lend themselves to isotopic study using oxygen isotope ratios in carbonate microfossils.
The growing importance of microfossils for biosteering horizontal wells is not mentioned; however, this contribution is helpful as a teaching aid.
The authors have succeeded in this as the book presents numerous case studies, which clearly demonstrate the unique applicability of these microfossils.
This allowed observation of opaque (carbonized) microfossils, and also assessment of the fossil nature of the isolated microstructures.
However, it is still unclear how these processes affect the internal microstructure of such remains, or even how to recognize bona fide preserved microfossils.
In petrographic thin sections cut perpendicular to the bedding, the microfossils appear only as very thin, dark streaks.
After having read the book, nobody can doubt that microfossils should become a standard tool in future environmental studies.
