Stratigraphy of Ototoka Beach, Whanganui Abstract This report aims to give an insight into the Stratigraphic history of the formations observed at Ototoka beach, Whanganui and to apply the use of various geological methods in examining individual sedimentary units in order to work out the environment that would have existed at the time of their deposition millions of years ago, and therefore we have constructed a history of environmental changes for the area over a large scale of time, such as the rise and fall of sea level and the co-occurring increase and decrease of temperatures as a result, which has given us a better understanding of how the planet’s environments change over time and how ours is changing at the present day. Introduction/Background We conducted our study at Ototoka Beach in Whanganui (Figure 5). The aim of our project was to work in groups to measure a section along the beach using pace and compass techniques whilst describing sediments, and collecting Micro and Macro paleontology samples for further study. We combined the data we collected on the fieldtrip with data we were given along with published literature to form an understanding of the stratigraphic record of Ototoka Beach. Regional Formations at Ototoka Beach (In Order): Lower Okehu Siltstone, Butler’s Shell Conglomerate, Upper Maxwell Formation, Mangahou Siltstone, Middle Maxwell Formation, Pukekiwi Shell Sand, Lower Maxwell Formation Aswell as conducting our own personal research at Ototoka
