the study area is located south of ghonabad in eastern iran. this area is situated between two major faults, darouneh to the north and dashtbyaz to the south. the movements of these faults cased major dislocation of this block. najmabad granodiorite to granite batholith is elongated trending east-west 2×8 km2. mineralization is associated with granite and monzonite. alteration zones are: propyl...

A new ichnogenus and ichnospecies of burrow, Katbergia carltonichnus, are described from Upper Permian and Lower Triassic rocks of the Karoo Basin, South Africa, where they are preserved in pedogenically modified overbank deposits that are interpreted as inceptisols subsequently gleysol overprinted. Sigmoidal burrows consist of a long (‡0.5 m) cylindrical tube, ranging from 1–2 cm in diameter, ...

A total of 17 sphene and 45 zircon fission track ages (FTA) are reported from the Piedmont Province of Pennsylvania, Delaware, and Maryland, the Reading Prong of New Jersey, and the Newark Basin of Pennsylvania. With the exception of one sphene sample, FTA fall within a relatively restricted age range: sphene 190-217 Ma (average 199 Ma) and zircon 143-218 Ma (average 184 Ma). Near concordance o...

In this study, a variety of test and analysis methods, such as cast thin sections, fluorescent scanning electron microscopy, fluid inclusions, etc., were comprehensively used combined with logging data, sedimentary systems, burial history other research results, to systematically study the diagenesis characteristics Middle Permian Lower Wuerhe formation–Lower Triassic Baikouquan formation reser...

Hydrocarbon generation in the Zechstein Main Dolomite and Upper Triassic potential source rocks of Polish Basin was investigated by 1-D thermal maturity modelling 90 boreholes across basin. This identified major zones potentially worthy further exploration efforts. The maximum burial depth reached >5 km during Late Cretaceous leading to organic matter. development reveals considerable differ...

Abstract Numerical 3D basin modeling is used to reconstruct the burial and temperature histories in onshore northeastern Netherlands, incorporating four main geological structural elements Groningen Platform, Lauwerszee Trough, Friesland Lower Saxony Basin. The framework based on recently published open access depth surface data; public vitrinite reflectance data from 28 wells are evaluate hist...

Carbonatites, usually occurring within intra-continental rift-related settings, have strong light rare earth element (LREE) enrichment; they rarely contain economic heavy REE (HREE). Here, we report the identification of Late Triassic HREE-Mo-rich carbonatites in the northernmost Qinling orogen. The rocks contain abundant primary HREE minerals and molybdenite. Calcite-hosted fluid inclusions, i...

Ornithischian dinosaurs are one of the most taxonomically diverse dinosaur clades during the Mesozoic, yet their origin and early diversification remain virtually unknown. In recent years, several new Triassic ornithischian taxa have been proposed, mostly based upon isolated teeth. New discoveries of skeletal material of some of these tooth taxa indicate that these teeth can no longer be assign...
