how can I get well defined youngest lithology on top

I can't get a well-defined lithology (the youngest-on top in blue-green colour). I assigned it within topography and inside polylines.

The contact looks good because it is following the polyline but the volume created is not complete. The output volume is smaller than I wanted to (which is within the polyline) and is patchy inside the polyline (contact between the younger and older lithology). This lithology is set as Erosion and offset limits as 'None'.

I tried to extent the ellipsoid ratios to Max: 50, Interm: 50 and Minim: 1.

Can you please advise if there is a work-around or if I am missing anything?

    Hi Maria,

    Try creating a new surface chronology as a deposit, using the same lithologies as your erosional chronology. Sometimes Leapfrog is too strict, and you need to choose the type of surface chronology to use depending on the result you want to achieve.

    I have even sometimes had to model sedimentary units as intrusive simply because, in my tectonic context, Leapfrog was unable to reproduce the correct geometry using erosional or depositional models.

    I hope it will help you.

    Cheers,

    François
