Petrographic and Mechanical Analysis of Grano-Diorite Deposits in the Qala Region, Dikundi Province, Afghanistan

Abstract

This research paper offers a detailed investigation into the petrographic composition and physical-mechanical properties of granodiorites in the Qala area of Dikundi Province. It starts with a geological overview of the region. It examines macroscopic and microscopic petrographic characteristics, paragenetic mineral composition, and critical physical-mechanical properties such as bulk density, water absorption, and uniaxial compressive strength. XRF analysis was also employed for accuracy. The research approach is purely investigative, with samples collected from the Qala area and tests conducted by international standards. These granodiorites' uniaxial compressive strength was approximately 94.02 Mega Pascals, signifying their exceptional structural durability. Additionally, these granodiorites exhibit a specific gravity of 2.57, considered high, and a water absorption rate of about 0.29%, making them highly suitable for construction. In summary, this academic research comprehensively analyses granodiorites within the Qala region, Dikundi Province. These findings are essential for evaluating the suitability of these granodiorites for various applications, particularly in the construction industry, contributing significantly to our understanding of this geological resource. The research recommends the need for government investment in the granodiorite mining sector, particularly in the Qala deposit. Detailed geological investigations are imperative to harness the full potential of this resource, generate employment opportunities, reduce dependency on stone imports, and explore international markets.
