Two large-scale north-dipping, low-angle normal faults cut the Everest massif at the top of the High Himalayan slab in Nepal. The upper fault the Qomolangma Detachment, follows the north slope of Everest from above the ‘Yellow Band’ at c. 8500 m on the Southwest Face down to the Rongbuk glacier. On the south side of Everest this fault places unmetamorphosed Ordovician mudstones and limestones a...

Abstract Granite is fractured according to the stress state during cooling stage, providing predispositions for later topographic evolution. This study clarified that triangular mesh‐like joints can be made granite and they become structural causes formation of rock towers corestones on ground. Tengu rock, which consists in Hiroshima, was investigated using an unmanned air vehicle. The were sha...

Abstract Granite rocks are currently one of the foremost raw materials that can be used for various economic purposes such as ornamentation and building materials, because they do not possess radioactive concentrations have good physical mechanical properties. The granite north Um Taghir connected to neoproterozoic integrated Arabian-Nubian Shield (ANS), which lies in Northeast Africa. Inductiv...

Microscopical studies were carried out, in addition to physico-chemical and mineralogical analysis, in order to evaluate the effect of parent material and weathering on soil genesis in forest regions of Lahijan. Two representative soil pedons in mountain landform developed on granite and andesitic basalt located about 8 km southeast of Lahijan were selected and sampling were taken from each hor...

Abstract In recent times, sustainable production of concrete is now considered a major issue due to continuous depletion raw resources. Thus, this current study investigates the physical and strength performance eco-friendly produced with combination periwinkle (PWS) palm kernel shells (PKS) used as an alternative for granite. Two mix ratios 1:2:4 1:1.5:3 (cement: sand: granite) were 28-day tar...
