the metamorphic complexes of south iran (namely sirdjan, hadji-abad and dolat-abad) are conspicuously related to two different cycles of orogeny and metamorphism . these two cycles are distinctly separate and have been mapped as such throughout the hadji - abad area . the older phase is definitely pre-cambrin, whereas the younger is considered to be early - kimmerian .

In recent years, a rapidly expanding database, especially in sensitive high-resolution ion microprobe (SHRIMP) geochronology, has led to signifi cant advances in understanding of the Precambrian tectonic evolution of the Grenville Province, including its Adirondack outlier, and the Mesoproterozoic inliers of the Appalachians. Based upon this information, we review the geochronology and tectonic...

this paper presents evidence on mesozoic inversion of basin bounding faults within the taleqan-gajereh-lar paleograben (tglp) in central alborz range. for this purpose, well documented stratigraphy data across the tglp together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. the tglp has evolved through the early and mi...

A common hypothesis for the rich biodiversity found in mountains is uplift-driven diversification-that orogeny creates conditions favoring rapid in situ speciation of resident lineages. We tested this hypothesis in the context of the Qinghai-Tibetan Plateau (QTP) and adjoining mountain ranges, using the phylogenetic and geographic histories of multiple groups of plants to infer the tempo (rate)...

A long-standing challenge in tectonics is to evaluate the role of inheritance and define initial conditions a geodynamic system, which are prerequisites understand model its evolution with some accuracy. Here we revisit concept “inheritance” by distinguishing “interface shape inheritance”, includes transient thermal state gravitational potential energy, “persisting encompasses long-lasting stru...
