__NOTOC__
{{OR/14/050}}
Borehole, well, seismic, mining, outcrop and selected parts of previous modelled data were combined to a single data file for each stratigraphic horizon (Table 4). Prior to that combination, each dataset was visually compared in GOCAD<sup>®</sup> and erroneous data or inconsistencies were identified and resolved. The main inconsistency resulted from the seismic depth conversion compared to well/borehole picks and mining information (the method of resolution is described in [[OR/14/050 Model datasets #Seismic data |Seismic data]]).
