Kwékam","doi":"10.9734/bpi/rtcams/v4/1993c","DOIUrl":"https://doi.org/10.9734/bpi/rtcams/v4/1993c","url":null,"abstract":"Achklun and Amgala are located in the North and South of Abéché, region of Ouaddaï (Eastern Chad). In Achklun and Amgala crop out, granites which are cross cut by diaclases and veins.Petrographic investigation of rocks shows that granites are of two types: (1) fine grains biotite granites constituted of quartz, orthoclase, plagioclase biotite andopaque minerals and (2) coarse grains amphibole biotite-granites made up of quartz, orthoclase, plagioclase biotite amphibole and opaque minerals.Structural feature investigated are diaclases and veins. Diaclases are observed in biotite granite and amplibole biotite-granite. They display NE-SW trend direction. Veins are observed in amplibole biotite-granite. They have granitic composition and pegmatitic texture. Veins display NE-SW dominant trend direction. The NE-SW trend direction suggests that their emplacement benefited from diaclase network.Geotechnical studies indicate that fine grains biotite granite is more resistant than amphibole biotite-granite. The resistant may vary from one station to another in the same rock type. This variation is due to mineral composition grain sizes and the intensity of fractures (diaclases).Base on field observations laboratory investigation the present work permitted to select the granite more adapted for various building. © 2019 Elixir All rights reserved.

Prior to the geotechnical experiments, the samples were crushed and then sieved to obtain 10/14 mm fraction to determine the mechanical characteristics. The LosAngeles trial was performed according to the prescriptions of standard NF P 18-573 (6). Micro Deval test was determined according to standard NF P 18-572 and that of the dynamic fragmentation was carried out according to standard NF P 18574 (7; 8). The specific density is determined according to NF P 18554 and NF P 18-555 by the liquid pycnometer method (9). Results and Discussions Petrographic study Granites petrographic study in the interesting area was carried out on six (6) samples. The granites of two studied sites are exposed in blocks and slabs on the flanks and at the top of hills (Fig 2a). It arises from this description two types of granite: fine-medium-grained granite and medium-grained and coarse-grained granite. From a microscopic point of view, we have biotite granite and biotite and amphibole granite. The percentage estimation was made using the abacus of the relative proportions of minerals in a rock by Michel Levy (1982) (10). The results obtained are shown in Tables 1 and 2. Mineralogical composition and grain size of the studied area play an important role in rock's resistance. The more the rocks are homogeneous (almost the same minerals and","PeriodicalId":20922,"journal":{"name":"Recent Trends in Chemical and Material Sciences Vol. 4","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84820245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
