Chapter Two Geology of the study area streams(Tainal and Tilie streams) wherein the grain size becomes smaller when it moves away from the stream channel . These deposits are formed during periods of flooding (Thornbury, 1969; Ritter, 1986). Alluvial fan deposits are found in the lower part of mountain valleys, Fig (2-5), where change in slope occurs, and they are excellent examples of water– spreading wash slopes (Bloom,2002), which consist of large amount of coarse grains plus some fine grains soil. River terrace deposits are observed at higher level from the present base level of erosion of Tainal stream, near New Sola village, Fig(2-6). They represent valley floors abandoned by the rivers as they start to cut down to the new and lower base level (sparks, 1972). Fig (2- 5) Alluvial fan (cone) deposits, at a distance 700m to the southwest of Darband Sutaw village (the trees are 1. 2 – 3.5m high) 16
Chapter Two Geology of the study area Fig (2-6) River terrace deposit of Tainal stream, near New Sola village (the trees are 3 – 4m high) 2-3 Microscopic study For precise description of the rocks, thin sections of various rocks of Sinjar and Kolosh Formations (which are prevalent at the proposed dam site) were made and studied under polarized microscope. In general, the microscopic inspection shows that the Sinjar Formation is composed of limestone rich in fossils and some pebbles, while the Kolosh Formation is composed mainly of clastic rocks with some limestone beds. The carbonate rocks were classified according to Folk(1962) and the clastic rocks according to grain size of rock components. These classifications are suitable in giving value to the material constant (mi) element of Hoek-Brown failure criterion which is used in the determination of the mechanical properties of the rock mass. A precise microscopic study of thin sections revealed the following types, as in table (2-1). 17
