1 Welcome 1 This is a document to explains the chosen concept to the animator. This will take you through a 5 section process to provide the necessary details to the animator before starting the animation. The legend on the left will indicate the current status of the document. The big Black coloured number will denote the current section, the Grey color would denote the completed sections, and the Turquoise color would denote the remaining sections. The slides having yellow background (like this one) are the 'Instruction slides' 2 3 4 5

2 Determination of relative timing between tectonics and sedimentation
Tectonic movements and sedimentary processes can interact in three ways. These are used to distinguish various types of sedimentary basins like pre depositional basin, post depositional, syn depositional basin. Related LOs: > Prior Viewing: Plate tectonics/Movement and sedimentary processes > Future Viewing : Course Name: Plate Tectonics Level: Post graduation Author: Arpita Roy Mentor: Prof. Soumyajit Mukherjee Title of the concept *The contents in this ppt are licensed under Creative Commons Attribution-NonCommercial-ShareAlike 2.5 India license

3 Learning objectives 1 After interacting with this Learning Object, the learner will be able to: Describe the relative timing of tectonic deformation and sedimentation 2 3 4 5

4 Key words 1 Pre-depositional basins: Due to tectonic activity, basin forms and later filled by depositional elements Syn-depositional basins: Sediment accumulation is affected by syn-depositional tectonic movements, e.g., differential subsidence, faulting, etc. Post-depositional basins: Basins are created by tectonic activity after the deposition of fluvial and lake deposits etc. Flow of Fluvial: The processes associated with rivers and streams Paleocurrent direction: Fluvial direction of ancient times Facies: Facies implies particular characteristics in particular environments Fault: Relative movement between the two blocks Synsedimentary fault: Fault develops during sedimentation process Reef: Reef is a kind of rock or highly topographic area that lies under the water 2 3 4 5

5 1 Master layout or diagram 2 3 4 5
Make a schematic diagram of the concept Explain the animator about the beginning and ending of the process. Draw image big enough for explaining. In the image, identify and label different components of the process/phenomenon. (These are like characters in a film)‏ Illustrate the basic flow of action by using arrows. Use BOLD lines in the diagram (minimum 2pts.)‏ In the slide after that, provide the definitions of ALL the labels used in the diagram You may have multiple master layouts. In this case, number the master layout. (e.g. Master layout 1, 2, 3…)‏ 2 3 4 5

6 1 Master layout 2 3 4 5 Animator should redraw diagrams
Text written in blue colour are instruction for animator, these would not appear in the final animation Text labeled in black colour would popup in animation Green arrows indicate the flow of the phenomenon/process Black arrows have to indicate labeling 2 3 4 5

7 1 Master layout:1 2 3 4 5 Reef Distinct Paleo-slope Shallowing Upward
Fig. 1 4 Pre-depositional basin: Due to tectonic activity, basin forms and later filled by depositional elements. The water depth in the basin decreases with time. Here, basin formed first due to some fast tectonic movement, then layer A deposits followed by layer B then layer C. The filling of basin causes the swallowing. 5

Q Syn-Depositional Basin R 2A 2B 2 3 4 Fig. 2 Syn-depositional basin: Tectonic movements control varying thickness of fluvial- and shallow marine sediments, and generate a basin fill structure, although a morphological basin barely exited. In the above figure, at first, layer A of varying thickness existed, a fault P developed that helped in subsidence of this layer and another layer Q is deposited above it. Another syn-sedimentary fault Q and sediment distribution has helped in differential subsidence and compaction of layer A as well as of layer B. This processes continues with addition of layer C above layer B. 5

9 1 Master layout:3 2 3 4 5 3 A 3 B 3 C Post-Depositional Basin Fig. 3
Post-depositional basin: These are created by tectonic movements after the deposition of sheet-like fluvial- and lake sediments, and some part of basin fill is removed by subsequent erosion. In Fig. 3A, sheet like sediments are deposited, then due to some tectonic movements, e.g. folding and faulting, the sheets get pulled down and form a basin like structure (Fig. 3B). Later, some part get eroded and giving it a shape of a morphological basin (Fig. 3C). 5

10 3 Stepwise description of process 1 2 4 5
The goal of the document is to provide instructions to an animator who is not a expert. You have to describe what steps the animator should take to make your concept come alive as a moving visualization. Use one slide per step. This will ensure clarity of the explanation. Add a image of the step in the box, and the details in the table below the box. You can use any images for reference, but mention about it's copyright status The animator will have to re-draw / re-create the drawings Add more slides as per the requirement of the animation 2 3 4 5

Shallowing Upward Distinct Paleo-slope 2 Fig. 1 Description of the action Audio narration Text to be displayed 1) Show Fig. 1 will appear on the screen with blue outline and label of Pre- depositional basin only. As the user clicks the diagram, layer A appears with label. Then after 5 seconds, layer B will gradually appear followed by layer C after another 5 seconds. [The animation should stop after the appearance of layer C with all labels on the screen.] Gradually the layers named A, B, C will appear. Rapid tectonic movements predate significant sediment accumulation and create a morphological basin, which is filled later by post-tectonic sediments. The water depth in the basin decreases with time. 3 4 5

Refer master layout-3 Description of the action Audio narration Text to be displayed 1) First show three different horizontal layers (as shown in Fig. 3A) 2) Then show the sagging down (basin is lowering down) of the three layers with a displacement on the right part of the Fig. 3B. This displacement has termed in this diagram as Fault 3) Sagging (basin is lowering down) will be continued in Fig. 3C. One horizontal layer should be marked with red colour here that indicates the eroded part of the Fig. 3C. Show this eroded part (affected by weathering agent) with dash black lines. Time gap between the appearance of each Figure should be around 15 seconds. Green arrows indicate the gradual appearances of the Figs. over here These basins are created by tectonic movements after the deposition of sheet like fluvial- and lake sediments and some part of basin fill is removed by subsequent erosion. 2 3 4 5

20 Self- Assessment Questionnaire for Learners
APPENDIX 1 Self- Assessment Questionnaire for Learners Please provide a set of questions that a user can answer based on the LO. They can be of the following types: These questions should be 5 in number and can be of objective type (like MCQ, Match the columns, Yes or No, Sequencing, Odd One Out). The questions can also be open-ended. The user would be asked to think about the question. The author is requested to provide hints if possible, but a full answer is not necessary. One can include questions, for which the user will need to interact with the LO (with certain parameters) in order to answer it. It is better to avoid questions based purely on recall.

21 Questionnaire: 1) What is paleoslope?
a) The direction of initial dip of an ancient land surface b) The direction of final dip of a present land surface c) The difference between the dip direction of initial and final points joining in a ancient land surface d) The slope along which fluvial sediments flow 2) What is meant by palaeocurrent direction? a) Paleocurrent direction is the direction of flow of water b) Paleocurrent direction is the direction of flow of water in ancient time c) palaeocurrent direction is related with fluvial direction of present days d) None of these

22 Questionnaire: APPENDIX 1
3) What is the utility ( in case of geological sciences) of relative timing between tectonic activity and sedimentation? Hint: [ It helps us to determine Paleocurrent direction, different characteristic features during facies change throughout the phenomenon] a) It helps us to determine palaeoenvironment b) Helps us to determine palaeocurrent direction c) Helps us to determine the exact time of sedimentation during tectonics 4) What is the reason of facies change in this (determination of relative timing between tectonics and sedimentation) phenomenon? a) Due to deposition of fluvial material b) Facies change is not related with this event c) Tectonic activity only the reason d) Tectonic activity as well as deposition of different sedimentary materials during different time of the event
