Extract Item-Values to seperate Text and give it spatial value

Hallo all together, I am working on a studyproject an i try to work with Gis-Data of a swamp to bring it in a spatial context. So i want to visualize different earth-layer. For that i have a lot of informations like the use of the area or the substrate. The question is: Would it be possible to seperate item-valus and bring it in a spatial context. So for example i have {0;456}: og-Hn//s, doble dash means sand-substrate begins 2 meters below peat-substrate. So i want seperate the data and bring it in a vertical volume. Is that possible ?
