I´m going to build a model in quartenary sediments. Is there a efficient way to model e.g. sand -lenses in gravel deposits.
This is a great question. Sand lenses can be generated in multiple of ways but my favorite is to use the Intrusion tool, this means you dont have to define your sand intervals as separate lithology codes, when you have more than one in a borehole.
We can set the sand Lense as the primary lithology in the intrusion tool and then apply a trend to the intrusion. The trend can then follow a specific structure, like the route of a river valley or generate ellipsoid style shapes on the horizontal. Whatever fits your depositional environment.
The help around intrusions is really useful: Intrusions (seequent.com)
I created a video on LinkedIn here about this topic: https://www.linkedin.com/posts/richard-lowries-43568b7b_seequent-leapfrog-3dmodelling-activity-7021288717440995328-6b77?utm_source=share&utm_medium=member_desktop
