Tectonic Framework of Sanjiang Tethyan Metallogenic Domain

analogous tectonic evolution of the tethyan and se asian regions*

the study of tectonic evolution of the tethyan and se asian regions indicates that these tworegions have each passed through southwardly progressing sequences of similar tectonic events. both regionshave experienced a southward island-arc subduction and back-arc spreading leading to continentaldetachment from gondwanaland, with an earlier southward island arc subduction of palaeotethys (tethyan...

Tectonic and Topographic Framework of Political Division1

Boundaries between the various topographic, geologic, and socio-political entities that span the Earth’s continental surfaces are determined by a myriad of complexly interrelated natural and/or cultural factors. Areas of large river basins, of lithologic units on geologic maps, and of nations exhibit size frequency distributions that are closely approximated by density functions in which diamet...

Petrogenesis of Negene basaltic volcanism associated with the Lut block, eastern Iran: implication for tectonic and metallogenic evolution

Tectonic Setting of Metabasites of the Neo-Tethyan Oceanic Remains in Sanandaj-Sirjan Structural Zone West of Isfahan, Central Iran

The study area is located in the western portion of Isfahan, in Shahrekord-Dehsard Terrene. This area is part of the Sanandaj- Sirjan structural Zone. In this area, metamorphosed igneous outcrops contain greenschist and metabasite rocks. These rocks have metamorphed into greenschist facies and belong to the Triassic-Jurassic age. The etabasite is mainly composed of plagioclase, amphibole, epido...
