Baseflow is an important component of river or streamflow.It plays a vital role in water utilization and management.An improved Eckhardt recursive digital filter (IERDF) is proposed in this study.The key filter parameter and maximum baseflow index (BFIrna
This article explored China\'s urban employment dynamics with particular focus on the city size effect.Big data derived from the largest recruitment website were used to ex-amine the direct and indirect impacts of city size on employment demand by using
The article considers the long-term (1941-2018) transformation of the Krasnodar valley reservoir,the largest in the North Caucasus.The main functions of the Krasnodar res-ervoir are irrigation of rice systems and flood protection of land in the Krasnodar
Post-collisional settings have long been discussed, both in the aspect of nomenclature, tectonic significance, sources of magmatism, and their relations to pre-collisional and intraplate settings. To many authors, it should be synonymous with late-orogeni

The rare earth elements (REE) are critical raw materials for much of modern technology, particularly renewable energy infrastructure and electric vehicles that are vital for the energy transition. Many of the world\'s largest REE deposits occur in alkal
The origin of low δ18O signals in zircons from the Early Cretaceous A-type granites in east- ern China has long been disputed. It is uncertain whether the 18O-depleted features were inherited from high-temperature hydrothermal altered source rock or resul
Dehydration melting of metasupracrustal rocks at mid- to deep-crustal levels can gener-ate water undersaturated granitic melt. In this study, we evaluate the potential of ～1.89–1.88 Ga me-tasupracrustal rocks of the Precambrian of southern Finland as sour
Whole rock elemental and Sr-Nd isotope geochemistry and in situ zircon Hf isotope geo-chemistry were used to identify the sources of the Neoproterozoic granites from the Socorro batholith, Socorro-Guaxupé Nappe (SGN), South Brasilia Orogen, Brazil. Zircon
Fractional crystallization of parental magmas of shoshonitic or silica-saturated, ultrapotas- sic affinity, with variable amount of concurrent crustal assimilation, may result in granitic and syenitic rocks. Typical plutonic members of the shoshonitic ser
