دراسة جيولوجية بتروغرافية -فلزية لصخور البلاجيوغرانيت-أبليت التابعة لأفيوليت البسيط/ شمال غرب سورية
Abstract
أجريت دراسة تفصيلة جيولوجية بتروغرافية فلزية لصخور البلاجيوغرانيت-أبليت التابعة لأفيوليت البسيط في شمال غرب سورية. تظهر هذه الصخور على شكل جيوب مترافقة مع جدد، و عروق الغابرو القاطعة شبه العمودية التي تخترق الصخور البيريدوتيتية. تتكشف كتل صغيرة من هذه الصخور في عدة مواقع إلى الجنوب من قرية الضبعة، مذيه (أم شخرط)،وأم قرط و جبل سيرلانلار، و إلى الشمال الشرقي من قرية العيسوية في عدة مواقع حيث أكبر مساحة لا تتعدى (2هكتار) . كما توجد أحياناً بعض العروق الكوارتزية.
تم تنفيذ عدد من المقاطع الجيولوجية, مما سمح لنا بفهم خصوصية صخور البلاجيوغرانيت-أبليت، وأهميتها البترولوجية. كما نوقشت مميزات هذه الصخور البتروغرافية و الفلزية، وتمت مقارنتها مع مثيلاتها في معقد ترودوس في قبرص حيث اقترحت لها التفسيرات الملائمة.
Detailed Geological, Petrographical and Mineralogical study of Plagiogranite-Aplite from Al- Bassit Ophiolite in N.W. Syria was done. They appear as pockets associated with semi vertical Gabbros dykes and veins which enter the Peridotite rocks. Some small blocks outcrop in several sites; in the South of Mathia (Om shochrot) village, Aldaba and Omqurt, Syrland Mountain, and in the N.W. of Issawiya village in several places and the biggest is about 2 hectare. Some times some Quartz veins are founded.
Some geological sections were executed, which helps in understanding the peculiarity of Plagiogranite-Aplite rocks and their importance, their petrographical and mineralogical properties were discussed and compared with similar rocks from Troodes Ophiolite Complex.
