The accretionary processes and the continental growth of Altaids are still controversial. Beishan orogen is situated in southernmost an ideal tectonic site to address these issues. In this study, we report results new field-based lithological mapping structural analysis on Huaniushan complex orogen, which composed blocks serpentinized ultramafic, gabbro, basalt, chert, limestone, other rocks wi...

Deep-water sandstones of the Delaware Mountain Group in west Texas and southeast New Mexico contained an estimated 1.8 billion bbl of original oil in place, but primary recovery from these fields is commonly less than 20%. East Ford field in Reeves County, Texas, which produces from the Ramsey sandstone in the upper Bell Canyon Formation, went directly from primary production to tertiary recove...

In this work, we report the first palynological age for base strata of Silves Sandstones Group in Algarve Basin, located Southern Portugal. The group is oldest sedimentary unit Basin and was deposited unconformably over late Pennsylvanian turbidites Mira Formation, which were folded faulted during Variscan Orogeny. comprises a detrital red bed succession, representing earliest phase sedimentati...

The Kopet Dagh mountains in NE Iran exhibit a 7-km-thick continuous sedimentary sequence recording detritus from exposed surrounding terranes the last 175 Ma. This work presents multi-disciplinary geochronologic and provenance analysis an attempt to identify date major geologic events along northern segment of Tethys reconstruct regional tectonic history Gondwana-related rifting until Alpine or...

Pseudorutile and kleberite are intermediate minerals formed during alteration of ilmenite to rutile. They difficult identify, as both have a range chemical composition occur small crystals commonly mixed with other minerals. Reference samples large pseudorutile kleberite, published X-ray diffraction analyses, were analysed establish characteristic Raman spectra. produced goethite-like spectrum ...

Results of U-Pb dating zircons from the Middle Devonian sandstones Mykolaivka Suite, taken junction zone between Azov Domain Ukrainian Shield and Donets basin, are reported. The rocks a drill core they occur beneath 210 m sequence mafic ultramafic volcanic that belong to Antonivka (D2-3) (D2) suites. In total, 28 isotope analyses were performed. predominant population (18 grains) yielded concor...

9 We report oxygen and carbon isotope results of bulk and detrital carbonate grains 10 from the last glaciation at IODP Site U1308 (re-occupation of DSDP Site 609). Oxygen 11 isotopic values of individual detrital carbonate grains from Heinrich events average 12 -5.4‰±1.3‰, presumably reflecting values of limestone and dolomite derived from 13 lower Paleozoic basins in northern Canada and north...

The character and distribution of cooling ages in modern river sediment provide useful constraints on rates and patterns of uplift and erosion within actively deforming mountain ranges. Such sediment effectively samples all locations within the catchment area, irrespective of remoteness. We evaluate how successfully detrital cooling ages may be used to constrain hinterland erosion rates by exam...
