... are no data between 900Ma and 1700Ma. Figure 2 presents angular velocity ω of the Earth's rotation. Data are approximated by polynomial equation of second power: (1) ω = -7,715E-12t 2 + 2,329E-08t + 7,190E-05 , where L is a total angular momentum of the Earth-Moon system, I + is inertial momentum of the Earth in respect of it polar axis, R is the Earth-Moon distance. ...

Mesozoic and Cenozoic granites are widely distributed in the South Lhasa terrane of southern Tibet and record information about subduction of the Tethys oceanic plate and the India–Eurasia collision. This paper presents petrological, geochemical, zircon U–Pb and Hf isotopic characteristics of Cenozoic intrusive rocks in the Luocang area, South Lhas...

Convergent continental margins are the major sites for the formation, differentiation, preservation, and destruction of continental crust. This article focuses on the Mesozoic crustal modification history of northeastern China from a magmatic perspective. During Mesozoic times, NE China was influenced by three convergent systems, namely the Paleo-A...

Generation of continental crust in collision zones reflect the interplay between oceanic subduction and continental collision. The Gangdese continental crust in southern Tibet developed during subduction of the Neo-Tethyan oceanic slab in the Mesozoic prior to reworking during the India-Asia collision in the Cenozoic. Here we show that continental...

The rock record present along the southeastern border of the Central Finland Granitoid Complex provides evidence for the geological evolution of the Paleoproterozoic Svecofennian orogeny from the magmatism of the Savo arc through paragneisses deposited in a passive margin setting to arc volcanism and the collisional final phases. The older Svecofen...

Active continental margins are shaped by subduction-related magmatism, and the Central Andes of South America are a prime example. The Central Andean orogen has evolved over the past 25 My via magmas ascending from the mantle and interacting with increasingly thickened continental crust. This process is reflected in the volumes and compositional va...
