Lluís,

   Your description looks similar to what mining geologists do to provide an
estimate of ore by grade and location; a 3D model of the ore body based on
core (or bulk) samples.

   A less expensive approach than using a LiDAR-equiped drone would be to
take depth measurements at points on a defined grid and use geostatistical
models to interpoate between unmeasured points. If you need to only map
strata, grass has capabilities for producing 3D models of geology but I've
not used them because I'm not a geologist.

   Something to consider while others provide more explicit ideas.

Regards,

Rich
