Abstract

Razdiobe dubina neogensko-kvartarnih formacija bjelovarske subdepresije analizirane su i kartirane geostatističkim metodama. Bjelovarska subdepresija sastavni je dio Dravske depresije. Reper „Tg“ ili „Pt“ i EK-markeri „Rs7“, „Rs5“, „Z'“, „Δ“ i „D'“ predstavljaju granice između pojedinačnih formacija unutar Dravske depresije. Ulazni podatci predstavljaju dubine do svakog EK markera i EK granice. Izmjerene dubine za svaki od markera i granice dobivene su pretežito iz seizmičkih profila. Metode kojima su ti podatci obrađeni su variogram, eksperimentalni semivariogram, histogram, F-test i t-test. Hipoteza o nasljednosti struktura na pojedinim EK-markerima i reperu „Tg“ ili „Pt“ Bjelovarske subdepresije ispitana je F-testom i t-testom. Nakon obrade ulaznih podataka pomoću softverskog paketa Surfer 8, konstruirane su strukturne karte repera "Tg" ili "Pt" kao i karte svih EK-markera. Metode korištene za izradu karata su kriging i metoda inverzne udaljenosti. Krosvalidacija korištena je kao numerički pokazatelj ispravnosti karata. Karte dobivene različitim metodama uspoređene su i opisane.

Abstract (english)

The depth distributions of Neogene-Quaternary formations of the Bjelovar subdepression were analysed and mapped by geostatistical methods. The Bjelovar supdepression is an integral part of the Drava depression. Electrologging boundary “Tg” or “Pt” and Electrologging markers “Rs7”, “Rs5”, “Z'“,„Δ“ and “D'“ represent the boundaries between individiual formations within Drava depression. The input data represents the drilled depths of each Electrologging marker and boundary. The measured depths for each marker and boundary were obtained from mesh of maps. The methods by which these data were processed are variogram, experimental semivariogram, histogram, F-test and t-test. The hypothesis of heredity of Electrologging markers and Electrologging boundary was tested by F-test and t-test. After processing the input data using the software package Surfer 8, maps of “Tg” or “Pt” Electrologging boundary and all the other Electrologging markers were constructed. The methods used to make the maps are kriging and inverse distance method. Cross-validation was also used as a numerical indicator of map correctness. Maps obtained by different methods were compared and described.
