Petrological, Geochemical and Mechanical Characteristics of Kooz Kunarr Khewa Calcite Marble Ahmad Faham Bawary α , Safiullah Noorzai σ , Usman Amin ρ , Sohaib Nader Ѡ , Ulfatullah Noori ¥ , Hamid Zaheer § & Abdul Haq Salih χ Abstract- This meth odical investigation's prim ary goal is to ascertain the geological, geochemical, mineralogica l, and mechanical characteristic s of the calcite marble found in Khewa. The article includes all important information about Khewa calcite marble, including its quality, constituent minerals, related elements, and other data. The procedures employed for the precise investigation and evaluation of the mine's characteristics include manipulative field observation, laboratory examination of Khewa calcite marble, and preliminary library studies concerning the research location. The calcite marble library research provided exact and accurate information about the location of the examined area's geology, as well as information about its tectonics and magmatism. In order for the laboratory analysis to determine the true geology of the area under study, including adjacent rocks, and the chemical makeup of the calcite marble, laboratory examination is required. Mica schist is the neighboring rock to calcite marble (a metamorphic rocks). The researcher gathered five random, exact samples of the calcite marble from various locations in the field to acquire this. For the desired outcomes, various techniques were used on the assembled simples. The purpose of XRF, also known as X- Ray fluorescence, is to determine the precise proportion of certain elements and oxides. In addition to the calcite, which is discovered in small amounts in the Mica schist rocks that surround the calcite marble in the XRF results, the percentage of calcite is over 55%. The Mica schist neighboring rocks of the calcite marble also contain a small quantity of uranium. The unique characteristics of calcite marble, such as their hues, structures, and linked minerals, were elaborated by the microscopic analysis. We obtained a range of results from physical and mechanical tests such compressive strength, and unit weigh. Wherever iron, aluminum, and nickel are found, calcite marble is very hard. Overall, Khewa calcite marble is very hard but suitable for construction. Keywords: marble, calcite marble, tectonic, XRF, khewa, nangrhar. I. I ntroduction arble is the product of the recrystallization of limestone or dolomite by contact metamor- phism or regional metamorphism The mineral composition is mainly calcite, which foams when it encounters hydrochloric acid Marble is also a large category of natural architectural decorative stones. Generally, marble cutting machines refer to metamorphic or unclassified carbonate rocks with decorative functions, which can be made into architectural stones or crafts. Marble is commonly used as Building Stone, Countertops and sinks, Floor tiles, Terrazzo - marble chips mixed with concrete to form floors, Tomb Stones construction and dimensional stone in Afghanistan especially in eastern part of Afghanistan Nangrhar province such as Khewa Calcite Marble. There are different varieties of marble in different provinces such as Kunarr, Bamyan, Kabul, Balkh, Kandahar, Herat, Paktia, Parwan, Helmand, Nangrhar, Faryab, Wardak, and Samangan. which are extracting and supplying to different countries and are prized for II. G eology of S tudy A rea It is necessary to consider the geological structure of this Tectonic Zone. The Tectonic zone of Jalalabad is located in eastern part of Afghanistan and the southeastern part of Nuristan zone. For the first time this was separated by Prof. Slavin and Syed Hasham Mirzad in year (1969) and Kalchanof and Sayed and added this zone in to Tectonic map and relate this zone with Alf Core. a) Jalalabad Tectonic Zone (Spinghar Block) The Jalalabad zone is a part of the depth of the past Cambrian which trace minerals lies above the ridges of the past Cambrian that form base of Geosyncline. These ridges appear in the mountain to the surface of the earth. In the eastern part of the Zone and in the southeastern part of Jalalabad city, on the left bank of the Kabul river and on the banks of Kunarr river the upper Paleozoic and lower Mesozoic sediment are visible on the ground and the central part of the Jalalabad zone is covered by Neogene Deposit. In addition, In Jalalabad zone there are sediments ranging from Archean Proterozoic to Quaternary system. The Archean Proterozoic structure are composed of various Gneisses, Quartzite, Amphibolite and crystalline slabs including the white M 1 Year 2022 95 © 2022 Global Journals Global Journal of Science Frontier Research Volume XXII Issue ersion I VII ( G ) Author α σ ρ Ѡ ¥ § χ : e-mails: ahmadfahambawary@gmail.com, safi03173@gmail.com, aminusman.148@gmail.com , babakarkhil1999@gmail.com , ulfatullahnoori2015@gmail.com, hasanhamid309@gmail.com , abdullhaqsalih@gmail.com
