تدراسة امكانية صناعة نوع جديد من الطابوق الفخاري من أطيان تكوين الفتحة (المايوسين الاوسط) وتحديد مواصفاتها الهندسية والجيوكيميائية والمعدنية

The results of engineering, geochemical and mineralogical analysis revealed that it is possible to manufacture a new type of pottery blocks with good building properties.This has been achieved by mixing of marl sediments from Fatَha formation (Middle Miocene) and recent clay sediments (from valleys around Mosul city) with different ratios of three types of alluvial river sand normally used for building purposes. More than one hundred cubic samples (10x10x10 cm) are prepared and pottered in a high-temperature (1100-1200C). This was followed by engineering and physical test after which a group of samples with certain good characteristics (here called typical samples) were chosen and further experiments were done on their new size (40x20x15 cm) to reach the best required quality.
