The basic friction angle (φb) tests are a common and practical method used to determine the shear strength of discontinuities. Tilt device is generally in experiments. In this study, effects anisotropy properties green mica schist rocks taken from copper mine site Kastamonu Hanönü district on residual angles were investigated. For purpose, experiments with specially designed tilt conducted drie...

Landscapes are subjected to surface denudation during their complex and non-linear evolution. In order quantify the in situ lowering and, thus, or soil erosion rates, new, multi-millennia archives needed must be rigorously tested. Large residual rocks, tors, basis for Tor Exhumation Approach. Here we present novel results on meta-sedimentary (schist) rock tors using this approach, which previou...

The anisotropy of deformation and strength behavior in quartz mica schist is fundamental to rock mechanics. Here, we concentrated on the practical application numerical simulation rock. First, existence engineering was reported, tested situ, analyzed. Then, a set specially designed multi-angle uniaxial compression tests conducted. Based these, two methods (explicit implicit) for were demonstrat...

Soil conservation and control of erosion is a basic problem in all countries. The goal of this research is to estimate erosion and sediment yield in Ekbatan Dam drainage basin by Erosion Potential Method (EPM), using Geographic Information System (GIS). The basin is located in Hamedan Province, west of Iran, in a cold and semi- arid region, with an average annual rainfall of 334mm. The study ar...

Semi-pelitic rocks ranging in grade from the prehnite–pumpellyite to the greenschist facies from southeastern Otago, New Zealand, have been investigated in order to evaluate the reactions leading to formation and breakdown of stilpnomelane. Detrital grains of mica and chlorite along with fine-grained authigenic illite and chlorite occur in lower-grade rocks with compactional fabric parallel to ...
