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
Approximately 17 meters thick, Unit A defines the lowest third of the Juniata Formation. Fragments of marine fossils, including bryozoans, brachiopods, and gastropods, are commonly found in the bottom-most portion of this unit of structureless mudstone and quartz arenite. Quartz grains in the sandstone beds of Unit A are typically immature and fine-grained, though the sandstone packages tend to coarsen upwards. Though typically structureless, intermittent bedding of the sandstone and shale packages is observed in this unit, and some areas display
Ziggy Marley is the son of the late Reggae great Bob Marley, in 2012 he wrote a song called, “Beach in Hawaii.” Though the title is upbeat, Ziggy talks about loneliness and how he wants to be with a certain person on the beach in Hawaii. Throughout the song, Ziggy uses repetition, imagery, metaphors and similes to drive the point that he is lonely in paradise.
In simple terms, the windward side of the island is where most precipitation takes place and the leeward side is the drier side of the island. Kauai is positioned in the track of the east-northeasterly trade winds, thus producing wakes in the lee. The leeside of Kauai seems to be of major interest in terms of studies of the wakes. Evidence of Kauai’s trade winds largely contributes to Kauai’s weather patterns. Particularly, weather patterns and environmental observations have geologically changed the wake of Kauai. Observations of the wake of Kauai have been of interests in geological studies because of changing factors connected to wind flow in terms of trade winds, erosion, changes in island temperature, cloud trails, and island-scale circulations in relation to both the leeward and windward sides of Kauai.
Sims et al. (1989) synthesized U-Pb zircon ages for the Pembine-Wausau terrane. Sims concluded that the volcanic rocks were generated from around 1889 to 1860 Ma as island arcs and closed back-arc basins above the south-dipping subduction zone (Niagara fault zone). Granitoid rocks in the terrane, emplaced from around 1870 to 1760 Ma, are mainly granodiorite and tonalite but include gabbro, diorite, and granite. These developed as island arcs above the Eau Pleine shear zone. The Niagara fault zone contains a relict ophiolite, suggesting that the rocks in the Pembine-Wausau terrane probably accumulated on
In recent years, ancient burial grounds have been frequently disturbed due to increasing surveillance by anthropologists and constructed on by state-of-the-art technology and are more critically protected than ever before. Understanding the importance of burial grounds gives an insight on the rich history of ancient Hawaii. They have influenced the burials performed, ancestors and their modern inhabitants, and how they have impacted modern Hawaii. Burial methods will range from the tallest peaks on land to burying those in the ocean. Ancestors influence these methods depending on their rank and actions, having their modern descendants have a choice to inherit these arrangements and protect their ancestors.
The sandy shores of beaches can be considered as a very harsh environment to live in (Ted Klenk, 1999). Survival in such a habitat requires an organism to withstand strong wave and current action, tidal rise and fall, unstable substrate, heavy predation and wide variations in salinity and temperature (The Otter Island Project). Any organism found in this type of harsh environment is specialized and highly adapted (The Otter Island Project).
Schulz’s article is split into five sections. The first section introduces the readers to Chris Goldfinger, a paleoseismologist at Oregon State University. Goldfinger was at a seismology conference in Kashiwa, Japan when the 2011 Tohoku
The study is carried out in Bicentennial Park to investigate and analyse the local area and expand on the understanding of geological and climatic concepts that can be identified through careful analysis of the area.
Sedimentary rocks interpret dinosaur habitats through encased environmental structures of the past. Through sedimentary rocks, paleoecologists’ can examine the arranged formation of sedimentary structures to specify what type of environment the dinosaurs’ lived in. An example of a specific sedimentary rock structure can be seen through formed weathering and ripple marks by how wind and sand formed distinct patterns in the past layered sediment. These arrangements provide interpretations on the structure of the sediment and the habitat of encased fossils, through modern day comparisons
Next, he offers information on the geologic setting, along with his associated methods and site information for the Copalis River and Nawiakum River. This information is then supported by a detailed discussion of their findings of charcoal, bones, shell and broken cobbles within their results section. Finally, Cole and associates conclude their research, assessing the implications of their findings and suggestions for future research. A list of references is attached to support the research cited throughout the
Kathleen’s first archaeological experience was in the Great Zimbabwe in Southern Rhodesia as a photographer where she was joined by Gertrude Caton-Thomson. This expedition had been made possible by her father’s facilitation and connections along with Margaret Fry’s persuasion. As she would prove useful on this excavation, being both industrious and reliable, her duties would expand beyond taking pictures to overseeing the workers assisting at the site. After she returned to England, at the completion of the Zimbabwe expedition, Kathleen joined Sir Mortimer Wheeler’s staff at his excavation at Roman Verulamiun (St. Albans), north of London. While there she would study Wheeler’s method of stratigraphic excavation. Wheeler’s findings were based on the concept developed by geologist William Smith where materials accumulate on a site through a sequence of layers that explain the historical timeline
By testing sediment and recording whether it was deposited under conditions of normal polarity and then measuring successive layers, we can build a time chart. By matching different charts from different areas with similar fossils, a more global correlation can be made.
This review is on the scientific paper ‘Architecture of an active mud-rich turbidite system: The Zaire Fan’ by Droz et al [2] published in 2003. The main purpose of this article was to take the seismic results from the ZaïAngo program, acoustic imagery and bathymetry information and present the architecture of the Zaire Fan.
The aim of this investigation is to look at the distribution of the ornate limpet, (Cellana Ornata) and the radiate limpet (Cellana Radians) on the rocky shore. We went to the rocky shore of Sirens rocks between Island Bay and Owhiro Bay, on Wellington’s South Coast. We are studying how our chosen organisms affect each other’s distribution patterns. We sampled in the low tide zone, mid tide zone, and high tide zone. The rocky shore we explored was 80 metre long, rocky terrain, bare rock platforms with rock gulley’s.
On the 9th of March, I went to Siren’s Rocks to investigate the community pattern, also called zonation, within the bounds of Island Bay’s Wellington Ecological Marine Reserve. The ecosystem of Taputeranga Marine Reserve takes the full impact of the Southern ocean swells. This Reserve is influenced by three different oceanic currents. This is an abiotic factor. The currents impact helps shape the rocky shoreline into the ecological community of different species of shore life into a pattern of different zones (zonation).
