Foraminiferal and Calcareous Nannoplankton Analyses 

It is important to date a Micropalaeontological assemblage in terms of standard Biozonation and necessary to recognize stratigraphically significant rock units based on their assemblage for inter well correlation.
Micropalaeontological assemblages can also be used to assess the depositional environment since different micro fauna are found associated with different water depths and also the planktonic benthonic ratio has a valuable indication.
This data is of fruitful value for geological and reservoir modeling since the depositional environment dictates the likely sand geometry, continuity and reservoir quality.
Similarly in carbonate environments the recognition of fore-reef, back-reef, or lagoonal facies is important for predicting the most likely location for the reef.
Semi-quantitative analysis refers to visually estimated abundances and is recommended for basic interpretation of age and depositional environment. Quantitative analysis provides absolute counts and is particularly useful for detailed, high resolution biostratigraphic studies in a sequence stratigraphic framework.

Palynofacies Analysis

Palynofacies analysis involves the identification of individual palynomorph, plant debris, and amorphous components, their absolute and relative proportions, size spectra, and preservation states. Spore coloration and visual kerogen analysis are used to assess the thermal maturation and source rock potentiality.
Detailed palynofacies analysis can be a great value for correlation and assist in defining sequence stratigraphic events by putting the relatively few taxonomically based palynological marker events in the correct stratigraphic context.
