In the processing Toolbox there is a tool called Variable Distance Buffer.
If you add a field to your data giving each type a width (field called
bufferwidth and it is 10, 20, 30 , 40 meters for each type) - you can
use that tool to automatically buffer each fault accordingly.
Good Luck!

Dear all,
I have a shape file with a field called “type”. In the “type” field
I have 4 kinds of samples ( 19 records).
See in the attachment.
The 4 samples are: normal fault, inverse fault, overthrust, syncline.
I would like to create a buffer with different distance for each
sample (the best it would be to obtain a shape with 5 different buffer
distances).
For example the buffer distance for the sample “ normal fault” is 30
m, for the “inverse fault “ is 20 m, for the “overthrust” is 50 m and
for the “syncline” is 20 m.
How I can do this kind of buffer??
Thanks A.L.
