1. A digital elevation model was created for the Las Mingachas outcrop area using aerial imagery and stratigraphic well data. Major flooding surfaces and sequential surfaces were reconstructed from digitized geological traces and well data. 2. A 3D volume model was constructed between the reconstructed sequential surfaces using gridded cells oriented in the paleoflow direction. Facies models were defined for each sequence set based on outcrop and well data.

1. Las Mingachas 3D outcrop model
1-. Digital Elevation Model (DEM) delimitation and drapping with the ortophotomaps of the
area (PNOA from IGN: Instituto Geografico Nacional), digital cartography of sequential traces,
stratigraphyc wells.
2-. Surface reconstruction from digitized traces & well tops.
a) Reconstructed sequential surfaces. M.F.S. of DSA. shows the surface grid lines.

2. b) Cross-view of sequential surfaces intersecting the DEM.
3-. 3D volume reconstruction between surfaces with “Cells”
The shape of the cells in plan view is oriented following the main paleoflow direction (towards
South-West) while the Layering (which represents the stratigraphy) is dependent of each
Sequence Set:

nature within each Sequence Set.
