ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...

Main features of mudslides in tectonised highly fissured clay shales

Mudslides are widespread in the world, especially in areas occupied by highly-fissured plastic stiff clays. Despite their strong impact on structures, infrastructures and, in general, human activity, the knowledge concerning the causes and mechanisms of mudslides is still rather limited. The paper reports some results of long-term research on mudslides in tectonised highlyfissured plastic clay ...

Mineralogy and Petrology of the Krishna Godavari Basin on Shore Area, East Coast of India

Shales are defined as fine-grained terrigenous sediments and rocks that contain 50% or more of terrigenous, and generally argillaceous, clastic components less than 0.062 mm in size. In the shales, clay-size components often dominate their rock properties, such as density, plasticity, parting, compatibility and swelling. Generally the size boundary between clay and silt is 4μm, but most clay mi...

Petrography, Mineralogy and Geochemistry of Kuhkamar Shale in the Roum section (South of Qayen): Application for Provenance and Tectonic setting

The Kuhkamar shale with a thickness of 354 m is composed of siliciclastic rocks (sandstone and shale). Petrography studies of the sandstones in this area show two petrofacies including arkose and sub-arkose. These sandstones composed of sub rounded to moderately sorted; therefore, compositionaly to texturaly, they are immature to submature with mono and polycrystalline quartz and k-feldespar. I...
