التكوينات الصخرية الرسوبية في الشريط الساحلي لحضرموت و المهرة و أهميتها في المجالات الإنشائية و الصناعية

الملخص EN

Sedimentary rocky formation in the coastal stripe for Hadramout and Al-Mahra spread widely , thus many quarries of cutting building stones are in coastal Hadramout, especially , in Al-Muklla , Ghail Bawazir , Ash-sheher , Al-Hami , Ad-dees and some regions of Al-Mahra are just a little active.

Many quarries and other facilities as well as cement factory are also engaged in similar activities other factories are under study and building.

.

Stones that are cut by saws classify as following ((Gypsum, Gypsumcarbonate, gypsum-carbonate-mud, gypsum-mud, sand-carbonate, as well as Anaedraat stones)) .The features that makes suitable and practical stones in building is its consistency and easy cutting as well as the purity.

these stones have been used in the process of building since along time ago in the coastal of Hadramout.

The stones are exploited and extracted manually or sometimes by blasting operations .

Nowadays the technical style of cutting stones by saws is used to give the required shapes and sizes , so a natural stone would become appropriate and easy to use it in the building field in different environmental and climatic conditions.Although of the positive aspects that are mentioned above , some concerns that appear from time to time such as the closure of some quarries or disqualification of inappropriate deposition for use because of the lack of required physical and mechanical properties in some unstudied sites.Strategraphic relations study , the measuring sections and the study of compositional structure of different geological unit and metal histological installation have been done during the completion of field work .

Required samples are collected and sent to Canada for analysis in order to evaluate them .

The results of many samples ((limestone, chalk, dolomite, Gypsum, Anaedraat )) gave positive indications Some of them are high-quality .

We should identify and test some of these sites and achieved geological , geochemical , physical and mechanical studies for the final detailed evaluation to determine the possibility of use in the appropriate fields in the structural and industrial side according to the qualities and the physical and chemical characreistics.
