    Three individual stratigraphic units are drawn on the left side of the diagram. Each unit is found in isolation from the other units. On the right hand side of the diagram is drawn a larger stratigraphic sequence that contains volcanic members that have been dated by the potassium-argon method. The ages in millions of years are indicated for each such unit in the sequence on the left side of the diagram. On the right side for all of the stratigraphic units the paleomagnetic data is indicated with an “N” for normal polarity and “R” for reversed polarity. In each of the three left hand sites a fossil hominid has been discovered among the sediments and is indicated by a (*).…

    Zircon Essay

    Depositional environment and the degree of homogenization of detrital zircon is directly related, where abrupt lateral and vertical variations in detrital zircon composition may record tectonic events in the source region. For example, the nonsystematic variations in the Winthrop Formation detrital zircon age signature suggest that these strata accumulated in a depositional setting characterized by abrupt changes in detrital input. This abrupt change could have been caused by a combination of active tectonism, heterogeneous source region, or limited mixing of a sediment derived from different areas within the source region. One downfall that accompanies zircon dating is the larger the heterogeneity of the zircon composition, the larger the uncertainty for determining accurate fine-scale characterization of the evolution of source regions. Grain structure of zircons also provides valuable information such that large grains that show no visual evidence of older cores but show well developed oscillatory zoning are characteristic of magmatic growth. Overall, one of the major benefits of analyzing the population of detrital zircon is the ability to link the basin to its source…

    The last great episode of the mountain building uplifted the entire Appalachian mountain chain from Newfoundland, Canada to Alabama. The mountains then were much higher than they are today. As the African tectonic plate gradually pushed against the edge of the North American plate, the original layers of the rocks were bent, broken and folded by faults. Huge masses of older, deeply buried rock were pushed up and over younger rocks. This is known as the Great Smoky Fault.…

    Next comes Hermit shale whose fern and conifer fossils as well as reptile and amphibian fossils indicate a coastal plain with many streams. Then comes the Coconino sandstone which is mostly quarts sand with vertebrate animal fossils indicating a dry desert environment in the area. Finally we come to the youngest layer of the Grand Canyon, the Kalibab limestone which has many marine fossils which indicate that the area was again under a shallow sea with clear water and a sandy bottom.…

    Plate Tectonics Theory

    Continental Collisions would be a possibility as this would birth mountain building. It is a theory that Europe and Asia collided millions of years ago. Marine life would have existed in the ocean basin between the land masses. As the continents approached, waters would recede from between them through subduction. This is caused by a later displacement of large blocks of the Asian crust by the mechanism continental escape. This developed the compressional mountains that led to the creation of the Urals. In addition to the creation of the mountains, the crust…

    Sequence Stratigraphy

    • 10 Pages

    Sequence stratigraphy is a method of stratigraphic interpretation that combines the chronological order of the accumulation of sediments, their stratal architecture and the geometric relationships of their facies to determine depositional setting and predict stratal continuity. The workflow of sequence stratigraphic analysis first identifies the genetic units and bounding surfaces that compose the stratigraphic section in outcrop, core, well-log and seismic data. The framework formed by the genetic units and bounding surfaces is tied depositional models that explain the recurring character of sequence stratigraphic units and surfaces and provides a common terminology for each of these models, whatever the tectonic setting, depositional setting, sediment types (siliciclastics, carbonates, evaporites) data set that is available for analysis (e.g., seismic data versus well logs or outcrop). It is generally assumed that many of the strata and surfaces are related to changes in base level driven by eustasy.…

    The Barberton greenstone belt in South Africa represents one of the best preserved successions of Archaean rocks. The rock sequences have experienced low grade metamorphism, which makes them ideal to study because the effects of alteration and secondary minerals are relatively small. The sedimentary rocks of the Fig Tree Group obtained through the drilling project “Peering into the cradle of life” are analysed for their geochemical composition . This paper deals with previous research into the geochemical composition of the rocks which can indicate what the environment of deposition may have been. Thin sections of the rock samples have been analysed to define the rock types and mineral phases present. Janet van der Brug – 3665542 Undergraduate Honours Research Project 07-06-2013 The main goal of the research is to establish the environment of deposition using the geochemistry and petrology of the samples as an indication of the processes and conditions. This question leads to other, more detailed questions: is there any chemical trace of early life; what redox processes were going on in original rocks; are sediments affected by hydrothermal overprinting? To answer those questions, the following questions give the data for interpretation: what are the major and trace elements of the rock; what are the main minerals? In this paper, the background of the research and known environmental conditions will be discussed, along with research into the petrology of some thin sections taken from the cores. Some preliminary results from the geochemical analysis are included but will not be discussed. In the discussion tentative interpretations of the literature and results will be taken together.…
