  • The reasons for the initiation of many landforms can in many instances be traced to various magmatic, thermal, tectonic, and sedimentological events, some of which took place in distant geological time. Many landforms are in reality multistage
  • Magmatic and metamorphic events, imprinted in the crystalline rocks of the so-called core mountains inside the Alpine structure of the Inner Carpathians, allow the re-construction of the history of the Rheic Ocean opening, its development and its
  • final closure. All magmatic suites, mafic and felsic, present in the Carpathians core mountains, show similarities to those found in the European Variscan Belt. All described- and dated metamorphic and magmatic events also have equivalents

  • The Pan-African (800-500 Ma) Older Granite suite of Nigeria is dominated by calc-alkaline, I-type magmatism and is a product of subduction processes at the eastern margin of the West African craton. The Kanoma and Sabon Gida composite plutons of NW
  • The granitoides of the southern part of the GDR may be considered as crustal anatexites generated in connection with the posttectogenic tectono-magmatic activation together with a regional metamorphism and postmagmatic ore deposits. The supply
  • On the basis of the petrologic characteristics and the lithostratigraphy of the Precambrian-Lower Palaeozoic metamorphites of the Ore Mountains the development of sedimentation areas and the chronological and regional course of tectonic, magmatic
  • The AA. report tectonic settings and geological features of Patagonia briefly and discuss some structural and geomorphological aspects that could be used to infer directions of magmatic flow of nearly horizontal lavas and to test stability of rock
  • . These ideas are supported by the magmatic development in this region. The ascertained processes of the structural development in this region. The ascertained processes of the structural development are well fitting into the Lower Permian picture of movements

  • seems to be controlled by magmatic influences as well as by the effect of temperature on groundwaters.

  • the magmatic plumbing system from the upper mantle to the crust of the Northeast Honshu arc.
  • The Sila Massif (Calabria, southern Italy) is a high-standing plateau with a rolling upland surface lying between 1000 and 1900 m. It is underlain by magmatic and metamorphic rocks thrusted over Mesozoic carbonate and terrigenous units. The Sila
  • glacial erratics from neighbouring fields above all representative of the magmatic and metamorphic genetic groups of rock. It is with a view to describing the cognitive, educational and geotouristic role this new object is playing that the present article
