How to make the geological model more natural along a reverse fault

[Changwan-planet]

Hello,

Thank you for opening this nice program.
I am making a geological model by using information obtained from multiple trench sections across a fault.

This question is related to the previous post: #814.
In the post, @AlexanderJuestel Ask me "is it necessary to distinguish them?"
Then, I didn't follow.
My bad... Now, I do not distinguish the two basements on both side of the fault.

The model has an interface between soft sediment and basement.
The geological structure has a reverse fault, and the interface also reflects the reverse deformation. The vertical displacement is changing along the fault.

I think I am almost done with making model, but it looks strange in the part of the reverse fault.

I uploaded two image of my recent geological model. The red line, which I drew, is the fault in both images. I think the model along the strike of the fault looks unnatural, specially inside of the green circle in the second image.

I think I am missing something. What is the problem? and how to look better? Which factor do I have to change?

I attached Points, Orientation, and Jupyter notebook (need to unzip the file for use). .

Miho_Points.csv
Miho_Orientations.csv
Miho_3D_modeling_integrate.zip

If you need more info, feel free to ask me.
Thanks

Hi,
can you explain why you are not adding the fault as a fault to the model? I do believe that would improve your result.

Hi,
looking at your data it seems that all your orientations are still labelled "SOFT", while the ones corresponding to the fault should be "FAULT".

@javoha Thank you so much!
I improved my model from your help!!
My next question is, How to change the color of the basement?
I was able to change the colors of other elements.
Most examples in the document show the color of the basement is mustard like my model.

I uploaded again my code and dataset.

*Another question @javoha
In the example, the points of the fault are mainly located under the element 250 (color magenta). But the final model shows that the fault model is extended to the element 0 (color blue).
If I would like the fault model to generate below the element 250, Which factor do I have to control?

Based on your comment, I hope to apply the knowledge in my model to limit the size of the fault model.

Hi,
I think not being able to change the color of the basement is a bug at the moment - I had the same issue. It will hopefully be fixed in the future (or you can of course contribute yourself and fix it for everyone).
Regarding the second question: You probably need to read a little more into the underlying structure of gempy. Which units are offset by a fault depends on timing/age relation. Still faults will always be displayed as continious over the model, as a visualization artefact, even if they do not affect all units.

@javoha
Thank you, Thank you so much.
Your answer is greatly helpful for me with quick response.
I will read more about gempy!
