Abstract
Pliocene volcanic rocks are considered as dominant rocks and form an important part of igneous succession in this region. The architecture type of Pliocene basalt is various as it consists of several diverse lithological formations, which vary from continuous basalts flow to scoria materials. The Pliocene basaltic rocks consist of several lava flows, which are divided into three primary petrographic groups: alkali basalt, augite alkali basalt and the basanite. The three petro-types can be classified geochemically from alkaline to sub-alkaline and termed as alkali olivine basalt. They have similar compositional ranges of major and trace elements. The geochemical composition shows that the basaltic Pliocene rocks consist of both partial melting and crystal fractions signatures. So the geochemical changing components can be considered as a result of crystal fractions that developed after partial melting process.

الملخص
تتكشف تشكيلات البليوسين النارية على مساحات واسعة من جنوب سوريا، وهي تشكل جزء هام من التتابع الناري في المنطقة.تتكون التوضعات البركانية البليوسينية في منطقة شهبا من تشكيلات ليتولوجية مختلفة، تتراوح بين صبات بازلتية دفقية مستمرة الى توضعات خبثية متماسكة سميكة أحيانا،ً تتضمن توضعات بيروكلاستية متنوعة. يُبنى التتابع البليوسيني الناري في منطقة شهبا من عدد متغير من الصبات البازلتية، المكونة بتروغرافيا من ثلاث مجموعات رئيسية هي: البازلت القلوي والبازلت الاوجيتي القلوي والبازانيت. يُظهر التركيب الجيوكيميائي للصخور البليوسينية، أن الصخور البازلتية المدروسة تبدي تغيرات على المحتوى التركيبي، يمكن اعتبارها أنها ناتجة عن عملية تجزؤ بلوري كان قد تطور عن عملية انصهار جزئي.
