| Abstract | ||||
| Basalt rocks are found in limited locations in Egypt, including basalt in Bahariya Depression. The study area has not received a geomorphological study of basalt rocks in particular. Therefore, the importance of research in studying basalt rocks in Bahariya Depression was a study in applied geomorphology due to its practical importance in the field of industry and multiple fields in line with the state’s interest in the process of sustainable development. Bahariya oasis is located in the western desert of Egypt at about 160 km west of Minya city. It has Elongated shape, was affected by tectonic activity, its exposed thick succession ranging from upper Cretaceous to Miocene in age. The depression is characterized by its flatness except for several isolated hills. These hills are Al-Hafuf, mount Hamada, and Matila Radwan in the southwest, and mount Al-mu'aysira and Mandisha in the north, where the Edges extend around the depression and affect the direction of wind movement. Main locations of Basalt rocks are in: Gebel El Hefhuf, Mandisha occurrence, El-agoz hill, Mayesra occurrence and Basalt hill occurrence. There are many associated landforms to Basalt rocks: sills, Doming in the upper sill, flows in el-hefhuf and Dykes Mineralogical and Geochemical discrepancies between the two batches could have originated from various petrogenetic processes including one or more of the following in the study. we propose that these chemical variations are linked to a mixture of superimposed processes involving mantle source, partial melting, and fractionation path. Significance of Basalt Fiber: known as “the green industrial material of the XXI-century”, combines ecological safety, natural longevity and many other properties. Its applications are surely innovative in many industrial and economic fields, from building and construction to energy efficiency, from automotive to aeronautic, its good mechanical and chemical performances. Hence Basalt Fiber has gained increasing attention as a reinforcing material especially compared to traditional glass and carbon fibers, and significance of Basalt fiber as a new reinforcing material. | ||||
