Help Drawing a Quaternary Deposits' Profile in Uppland, Sweden

Click For Summary

Discussion Overview

The discussion revolves around the task of drawing a Quaternary deposits' profile in Uppland, Sweden. Participants are seeking guidance on how to interpret surface data and represent it in a 3-dimensional stratigraphic profile, focusing on the arrangement and characteristics of various Quaternary deposits based on provided figures and contour lines.

Discussion Character

  • Homework-related
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant suggests starting with the altitude information to create a surface profile along line AB and then adding deposits in chronological order based on their age.
  • Another participant expresses uncertainty about how to determine the shape and length of the profile, indicating a need for clearer guidance.
  • There are questions about how to connect different deposits and whether to assume equal height intervals for contour lines, with one participant suggesting that closed loop contours indicate hills.
  • A detailed description of the stratigraphy in the region is provided, outlining the types of deposits and their formation processes, including glacial clay, postglacial clay, and various organic materials.
  • One participant emphasizes the need to show attempts at the homework and ask specific questions, reminding others of forum rules against completing assignments for others.
  • Another participant attempts to guide a peer through an example, explaining how to interpret contour lines and sketch the profile based on height values.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to approach the drawing of the profile, with multiple viewpoints and uncertainties expressed regarding the interpretation of the data and the representation of the deposits.

Contextual Notes

Participants note that the figures provided are not very clear, leading to difficulties in interpreting contour heights and determining the correct connections between deposits. There is also mention of the need for specific questions to facilitate better assistance.

I can’t see Any? I am sorry I’m really bad at this! Its a onlinevourse I’m taking that I just need to pass to keep my spot at another
You can't see the image in post #29?

This is strange... your post is identical to post #24 of nearly a week ago, down to the typos.

That is so strange, I did not write that now haha? What I wanted to say is that I still don’t know how to draw the curve according to the task

Draw an xy grid just like the one in the graph in post #29.
Measure along the AB line in the map you were given to the places where it crosses the contour lines.
Find the corresponding points along the x-axis in your graph, and along the AB line in the graph
In post #29. You should find that the heights in post #29 are close to multiples of 5m. If so, mark at that height on the graph you are making. Where possible, check that the height matches that in the map you were given.

Thread closed. The OP has been given a lot of good suggestions, but has failed to act on them.
