Tectonic geomorphology is part of Earth Sciences, which deal with study of the interaction of tectonic and geomorphology. In other words it studies the effective tectonic processes in forming and changing the landforms. Geomorphic and morphometric indicators are suitable tools to the morphotectonic analysis for different areas. These indicators are used as the base tool to identify and recognit...

Despite intensive research into the coupling between tectonics and surface processes, our ability to obtain quantitative information on the rates of tectonic processes from topography remains limited due primarily to a dearth of data with which to test and calibrate process rate laws. Here we develop a simple theory for the impact of spatially variable rock-uplift rate on the concavity of bedro...

Abstract The Banchetta-Rognosa tectonic unit (BRU), covering an area of 10 km 2 in the upper Chisone valley, consists two successions referred to a continental margin (Monte Banchetta succession) and proximal oceanic domain (Punta Rognosa respectively. In both successions, Mesozoic meta-sedimentary covers discordantly lie on their basement. This paper presents new data lithostratigraphy metamor...

The population of Rudbar in northern Iran, is due to Steep slopes of topography, Sloping Loose Materials, active tectonic phases, Construction of roads and railways, from areas prone to landslide events .In this reaserch, in the first phase, based on ground surveys, a geologic map of 1: 25,000, satellite images and  other data of Rudbar region, range and status of landslides of the region were ...

در این پژوهش از روش آماری سطح پاسخ جهت بهینه سازی شرایط فرآیند هیدرولیز پروتئین روده و معده ی گوسفند با استفاده از آنزیم آلکالاز (2.4l)، استفاده شد. فاکتورهای مورد بررسی در این تحقیق دما، زمان و نسبت آنزیم به سوبسترا بودند که برای رسیدن به بیشترین میزان درجه هیدرولیز و بازیافت نیتروژن این متغییرها در محدوده ی دمای 52-43 درجه سانتیگراد، زمان 190-65 دقیقه و مقدار آنزیم 95-50 (anson unit/kg protei...

The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...

Basalts in the Gasht-Masuleh area crop out in the SW Fuman, Gilan Province, and are exposed in the Jurassic and Late Cretaceous units in this area. Whole rock chemistry shows that the rock samples have Mg numbers between 30 and 31.7. Rare earth element patterns (REE) indicate light REE (LREE) enrichment and heavy REE (HREE) depletion (LaN/YbN= 7.7-9.8). Nb, Ta and Ti negative anomalies in primi...

ghalajeh synclinal is extended on the south of kermanshah province from northwest to southeast. considering the permanent tectonic movements in quaternary and current age in studied region, the alluvial fans of the region is a good reason for evaluation of such movements. the morphology and morphometry properties of alluvial fans are severely under the effect of the tectonic activities. the aim...
