| Abstract | Bore holes were drilled in the Senonian limestone of the Hedils-Jalta area (northern Tunisia) in order to determine their potential as an aquifer. Structural, tectonic and hydrogeologic data compilation shows the discrimination of productive and not productive zones. Differential hydraulic productivity was recognised with four distinct productive geological zones separated by a sterile corridor trending NW–SE. The structure consists of two compressional dihedrons, limited by two conjugate strike-slip faults, trending NNE–SSW and nearly E–W. The reduction of the (1) potential reservoir, (2) the low hydraulic productivity of the central band, (3) the torsion of the fold axis in eccentric arcs on both sides of the compressive relay and (4) the differential hydrogeological zonation are all related to the distribution of stress in the interference zone between conjugate strike-slip faults and to the reorientation of the stress field in their vicinity. This study constitutes a main database in establishing strategies for groundwater exploration in the similar zones.وقع إنجاز العديد من الآبارالعميقة في الأحجارالكلسيّة للعصرالطّباشيري الأعلى بمنطقة هذيل-جالطة الواقعة بشمال البلاد التّونسيّة، قصد تحديد ثرواتها المائيّة الجوفيّة. إنّ نضد التقسيمات البنيويّة و التكتونكيّة مع المعطيات الهيدروجيولوجيّة، تمكّن من تمييز مناطق منتجة وأخرى غير منتجة للمياه الجوفيّة. كما وقع تسجيل إنتاجيّة مائيّة تفاضليّة متكوّنة من أربعة مناطق جيولوجيّة منتجة متباينة يفصل بينها رواق عقيم ذو اتجاه شمال غرب-جنوب شرق. تتكوّن التركيبة البنيويّة من القسمين الضاغطين المحدودين بالفالقين الإنزلاقيّين والمترافقين، والمتجهان على التوالي شمال شمال شرق-جنوب جنوب غرب و قريب من شرق-غرب. إنّ انخفاض قوّة الخزن (1) وضعف الإنتاجيّة المائيّة(2) للشّريط الأوسط، والتواء محاورالجبال بالمناطق المجاورة لتتابع الإنكسارات المضغوطة (3) والتّباين الهيدروجيواوجي(4) جميعهم متّصلون بتوزيع حقل الضغط بمنطقة الإضطراب المتواجدة بين الفالقين الإنزلاقيّين و المترافقين وكذلك بإعادة توجّه حقل الضغط بالمساحات المجاورة للإنكسارات العميقة. إن هذه الدّراسة تشكل قاعدة بيانات وأداة مساعدة على إتّخاذ القرار في تأسيس إستراتجيات لاستكشاف المياه الجوفيّة بمناطق مماثلة. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
