In the present study, we unveil real significance of mylonitic reworking polymetamorphic crystalline basement in Serre Massif Calabria (Southern Italy). We use a multidisciplinary approach to comprehend structural, microstructural and petrologic changes that occurred along a, so far, not much considered shear zone affecting Variscan lower crustal rocks. It was never before studied detail, altho...

We analyzed the tectonics and stratigraphy of Southern Great Tarakan Basin to determine its tectonic evolution during Mesozoic-Cenozoic Eras, basin geometry, potential hydrocarbon using integrated surface subsurface data. can be divided into three sub-basins, Berau, Muara, South Tarakan. They comprise deposits Jurassic Quaternary age, which assigned five mega sequences based on their lithologic...

The Earth is composed of layers of different composition and physical properties, principally the solid central core, the fluid peripheral core, the viscous mantle, and the solid lithosphere. The lithosphere is comprised of the upper mantle and the crust, the outer shell of the Earth. There are two types of lithosphere, according to the crust resting on the solid mantle lithosphere (lithospheri...

Within Eastern Ukraine, in the course of previous studies, neotectonic movements were established, caused by both salt tectonics and Attic (post-Miocene - pre-Pliocene) thrust dislocations northeastern vergence. They are partially displayed modern relief. The aim study was to reveal structural results interaction post-Pliocene fold-thrust deformations Ukraine. Research methodology. base Cenozoi...

This paper looks at the challenges confronting plate tectonics— the ruling paradigm in the earth sciences. The classical model of thin lithospheric plates moving over a global asthenosphere is shown to be implausible. Evidence is presented that appears to contradict continental drift, seafloor spreading, and subduction, as well as the claim that the oceanic crust is relatively young. The proble...

Continental drift is the movement of the Earth's continents relative to each other. The hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s, that a sufficient geological explanation of that movement was understood. (This arti...

Introduction. The once popular idea that changes in planetary volume play an important role in terrestrial orogeny and tectonics [ I ,2] was generally discarded with the acceptance of plate tectonics. It is nonetheless likely that the Earth has been steadily cooling over the last 3-4 billion years [e.g., 3,4], and the global contraction that accompanied such cooling would have led to a secular ...

The Precambrian metamorphic rocks in the southern region of Espírito Santo State(southeastern Brazil) is intercepted by ductile and brittle/ductile shear zones over which towns like Guaçuí, Marechal Floriano Domingos Martins were established. In years 2014 to 2016 State faced worst drought past 80 years. situations that, only source fresh water available underground. Therefore, purpose this stu...
