1. Introduction Among sedimentary systems that are rich and poor in terms of sediment load, a different organization of the sand dunes can be seen. Barchan dunes are one of the accumulative landforms of wind that are considered from poor sedimentary systems in desert environments. The dunes are the crescent shape, and have two horns at the end. Along the horns the prevailing wind direction...
one of the most intensive occurrences of magmatism in iran was in the middle jurassic period. among the granitoid intrusions in this period as discrete bodies or complexes can be pointed to aligoodarz, alvand, astaneh, boroujerd, malayer, and chah-dozdan in the sanandaj-sirjan zone; shir-kuh and ayrakan in the central iran zone; shah-kuh, sorkh-kuh and kalateh-ahani in the lut block. these gran...
water distribution method based on the type of water conduits can be divided into two groups, namely, open and closed systems, while on the basis of the energy of the water flow, the two groups are gravity flow and pressurized flow. open channel type conveyance and distribution is achieved by gravity and includes channels made by embankment construction, excavation, or construction of prefabric...
geochemical aspects of na-metasomatism in sargaz granitic intrusion (south of kerman province, iran)
the sargaz granitic intrusion has been emplaced in sargaz ophiolitic suite, south-east of sanandaj-sirjan metamorphic zone, south of kerman province. the central part of the intrusive body contains pinkish coarse-grained granite, but the fractured northern part, neighboring chah-mazraeh fault, has been subjected to pervasive na-metasomatism and related subsolidus reactions. in the northern alte...
Halalan Manganese ore deposit is located in Torud-Chah Shirin volcano-sedimentary band and the northern part of Central Iran structural-sedimentary zone. The outcropped rocks in the area include metamorphic complex with lithology composition of slate, phyllite, schist, marble, limestone, dolomite and slightly metamorphed sandstone with Early Jurassic age. Manganese mineralization has occurred i...
