High-res o lu tion 3D geo log i cal model of the baux ite-bear ing area Crvene Stijene (Jajce, Bosnia and Herzegovina) and its ap pli ca tion in on go ing re search and min ing. Geo log i cal Quar terly, 62 (1): 100-119, doi: 10.7306/gq.1396Three-di men sional (3D) geo log i cal mod els are use ful tools in var i ous geo log i cal, min ing and other en gi neer ing ac tiv i ties.Geo log i cal model shows strati graphic, struc tural and lith o logic set tings of the study area in 3D space, and serves as a 3D geodatabase for a va ri ety of in put data. The study area is one of the baux ite-bear ing sites, Crvene Stijene, near Jajce (Bosnia and Herzegovina). Dur ing the last de cades, a num ber of geo log i cal, geo detic, min ing and other data were col lected through in ten sive geo log i cal re search and min ing (ex plo ra tion), with the aim of find ing and ex ploit ing baux ite de pos its. There fore, se lected area is a great poly gon for the im ple ment ing and test ing of workflow for the con struc tion of a 3D geo log ical model of baux ite-bear ing field and its ap pli ca tion in cur rent and fu ture re search and min ing. Pre sented workflow in cludes col lec tion, dig i ta li za tion, or ga ni za tion and vi su al iza tion for dif fer ent types of ex ist ing and new data (600 bore holes, geo log ical maps and cross-sec tions, DEM, struc tural mea sure ments from the sur face, as well as in tun nels and adits) in 3D geo log ical da ta base. For this study, dif fer ent types of geo log i cal ob jects, fault planes and geo log i cal sur faces were mod elled with dif fer ent in ter po la tion al go rithms. The con structed model is in ter ac tive and it can be eas ily up dated by new in put data from cur rent re search and ex ploi ta tion ac tiv i ties: bore holes, un der ground min ing ob jects, etc. The 3D geo log i cal model rep resents a rel e vant foun da tion for plan ning new re search and min ing ac tiv i ties. Fur ther more, newly found de pos its and their volumes can be quickly mod elled, con toured and cal cu lated. Pre sented mod el ling workflow is ap pli ca ble to other ar eas and other min eral re sources.
