Abstract

Statistical analysis of the Late Miocene sequences on the southeastern Danube Basin margin based on borehole data

Highlights

Subsequent regression of the Lake Pannon took place through mentioned deltaic systems prograding from the north
The used database contains more than 700 boreholes reaching average depth of 300 m, which lithological logs were digitalized according to main grain size in each described stratum and considering the origin of the layer
The shelf slope prograded to studied area across the basin floor environment of the central depression at ~9.0 Ma

Summary

Introduction

Subsequent regression of the Lake Pannon took place through mentioned deltaic systems prograding from the north. The used database contains more than 700 boreholes reaching average depth of 300 m, which lithological logs were digitalized according to main grain size in each described stratum and considering the origin of the layer. For purposes of the statistical analysis were created (1) pie charts of percentual share of each described lithotype (clays, fine sands, medium and coarse sands, gravels) for individual stratigraphic unit; (2) histograms of the percentual content of coarse (medium to coarse sandy and gravely) layers in a lithological column for each stratigraphic unit; (3) histograms of single unit/stratum thickness for each lithotype in each stratigraphic unit; and (4) interpolated maps of spatial distribution of coarse layers (percentual content) in each stratigraphic unit.
