Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them. The primary objective of biostratigraphy is correlation, demonstrating that a particular horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local v… Web11 Apr 2024 · Despite the lateral variation, a stratigraphic way-up criteria was discerned by Crookshank (1963) where quartzite rocks occupy the lowest stratigraphic level, followed by banded magnetite quartzite (BMQ), andalusite schist, basalts and tuff, sericite schist and quartzite, in an ascending order.
