Abstract

: This paper presents a petrographic study of the Upper Miocene sandstones from exploration wells in the Sava and Drava Depressions in the North Croatian Basin (SW of the Pannonian Basin System), Central Europe. These sandstones represent the most important reservoir rocks for oil and gas in Croatia. A total of 130 core samples from depths of more than 3000 m were examined. The sandstones generally have a feldspatho–litho–quartzose (fLQ) composition. The modal composition of samples from the Sava Depression is Q 39.2–61.0 F 8.9–26.0 L 26.1–42.3 , and Q 40.6–63.5 F 6.6–23.3 L 20.9–42.3

北克罗埃西亚盆地上中新世砂岩的岩石学:了解潘诺尼亚盆地体系西南部最大储层的成因

本文对中欧北克罗埃西亚盆地(潘诺尼亚盆地系西南)萨瓦和德拉瓦坳陷探井的上中新世砂岩进行了岩石学研究。这些砂岩是克罗地亚最重要的油气储层。总共检查了130个岩心样本，这些样本来自3000米以上的深度。砂岩一般具有长石-岩-石英(fLQ)组成。萨瓦坳陷样品的模态组成为Q 39.2 ~ 61.0 F 8.9 ~ 26.0 L 26.1 ~ 42.3, Q 40.6 ~ 63.5 F 6.6 ~ 23.3 L 20.9 ~ 42.3

期刊介绍： GEOLOGICA CARPATHICA covers a wide spectrum of geological disciplines including geodynamics, tectonics and structural geology, volcanology, stratigraphy, geochronology and isotopic geology, karstology, geochemistry, mineralogy, petrology, lithology and sedimentology, paleogeography, paleoecology, paleobiology and paleontology, paleomagnetism, magnetostratigraphy and other branches of applied geophysics, economic and environmental geology, experimental and theoretical geoscientific studies. Geologica Carpathica , with its 60 year old tradition, presents high-quality research papers devoted to all aspects not only of the Alpine-Carpathian-Balkanian geoscience but also with adjacent regions originated from the Mediterranean Tethys and its continental foreland. Geologica Carpathica is an Official Journal of the Carpathian-Balkan Geological Association.
