The modes of formation clastic rocks result in a wide variety microstructures, from poorly-sorted heterogeneous to well-sorted and nominally homogeneous rocks. mechanical behavior failure mode is known vary with microstructural attributes such as porosity grain size. However, the influence size distribution, particular degree polydispersivity or modality not yet fully understood, because it dif...

During the late Oligocene to early Miocene residual Magura Basin was located along front of Pieniny Klippen Belt (PKB). This basin supplied with clastic material derived from a south-eastern direction. In Male (Little) Mts. in Poland, Oligocene/ Kremna Fm. Nappe (Krynica subunit) occurs both PKB as well tectonic windows within PKB. Lenses exotic conglomerates contain frequent clasts Mesozoic li...

The Mesoproterozoic Gaoyuzhuang and Wumishan Formations are major geothermal reservoirs in the Hebei Province, North China. Compared to exploration of resources heat-controlling structures, carbon oxygen isotopic records two formations limited. Here, we present integrated field, petrological, geochemical, carbon, data carbonate rocks from Formations. Formation is characterized by higher CaO MgO...

The collaborative federal–provincial Southern Indian Lake project in north-central Manitoba covered an area of more than 3500 km 2 the Trans-Hudson orogen. Regional-scale geological mapping, sampling, and lithogeochemical, isotopic, geochronological studies resulted identification distinct assemblages supracrustal rocks varied episodes plutonism. A granodiorite gneiss dated at ca. 2520 Ma is in...

The rock composition of thick-layer, coarse-grained clastic reservoirs is complex. There are large variations in granularity and poor selectivity. Reservoirs rocks extremely heterogeneous. Current conventional parameters for quantitative characterization reservoir heterogeneity, such as the calculation values permeability variation coefficient, rush contrast, unbounded, have different represent...
