The objective of this study is to demonstrate the power of integrating rock physics theory, measurement and simulation to improve facies prediction in an unconventional limestone and shale reservoir. Reliable facies prediction is a challenge in unconventional reservoir characterization because of complex geological heterogeneities. Both deterministic and probabilistic approaches are commonly us...

We discuss the assembly and tectonochronology of Cycladic Blueschist Unit (CBU) in central Aegean Sea region, Greece, as a composite, subduction-related, high-pressure (blueschist to eclogite facies) stack nappes. Our work is based on review geochronologic data from islands Tinos, Syros Sifnos. In addition, we present large set 34 new, internally consistent Rb-Sr multimineral isochron age these...

Abstract The Algyő High (AH) is an elevated crystalline block in southeastern Hungary covered by thick Neogene sediments. Although productive hydrocarbon reservoirs are found these sequences, numerous fractured also occur the pre-Neogene basement of Pannonian Basin. Based on analogies, rock body AH might play a key role fluid storage and migration; however, its structure therefore reservoir pot...

Abstract This contribution provides insights into ocean-floor hydrothermal metamorphism of the fast-evolving Dinaridic Neotethys. Mineralogical, geochemical and Sr isotope data collected from altered ophiolites non-ophiolite basalts/andesites tuffs active continental margin are consistent with alteration trajectories that reflect host-rock composition. suggests fluxes were restricted within a s...

The Ciletuh Mélange Complex in West Java, Indonesia, provides evidence of early Cenozoic subduction. This study aims to investigate the stratigraphic position, geological structure, metamorphic facies, and protoliths rock units. research methods employed mapping, petrology, geochemical analysis. samples collected exhibit different including zeolites, greenschist, epidote amphibolite. Protoliths...

Transmission electron microscopy and 3D focused ion beam/scanning microscope nanotomography are applied to grain phase boundaries between quartz, plagioclase, K-feldspar, clinopyroxene, amphibole, calcite. The samples come from metamorphic, plutonic volcanic rocks, hydrothermal experienced cooling decompression after highly variable P–T peak conditions. Most of the partially open in range up se...

Aquifer systems are considered in which measurements of logpermeability (Y) at a 1E-2 m support scale are unimodally distributed as taken within the 1E0 to 1E1 m scale of individual sand and gravel (sg) lithofacies, are weakly multimodal at the 1E1 to 1E2 m scale of assemblages of these facies, and are strongly multimodal at the 1E3 m scale of complexes of sg facies assemblages juxtaposed with ...

in order to investigate deformation history preserved in the calcite twins in the hinterland of zagros, several samples have been collected from calcschists of the paleozoic sargaz complex in the faryab area, se iran. these samples are related to f1-recumbent folding and thrust shear zones. the twin width is about 1 and 3.8 µm (thin-twin regime); the twin strain amounts 5 and 10%; twin intensit...

New U-Pb monazite ages from amphibolite-facies metasedimentary rocks the Tennant Region, Murphy Inlier and intervening East area, together with existing data, reveal presence of an 1860–1840 Ma tectono-magmatic domain over 600 km long towards centre North Australian Craton. In-situ ion probe dating biotite-hosted in schist Region yielded age 1858 ± 7 Ma, which is attributed to north–south short...
