Zhaheba area of ophiolite belong to Zaheba ophiolite belt a Arman is part of the whole northwest trending

metamorphism widespread

ophiolite output obviously controlled by faults

its internal fault is developed. The ophiolite is only distributed mainly in South West from the dam

ultramafic rocks

magnesium mafic rocks

siliceous rocks. Zaheba ophiolite occurrence has the characteristics of ordered structure and tectonic mélange

the ultramafic rocks are depleted mantle rocks

with cold emplacement intrusive

constitute ophiolite bottom unit in genesis and mafic magma formation. There is no direct relation between the zaheba ophiolite is composed of rocks and complete facilities

although the tectonic melange and disordered fragments stacked but the inside of each cell retains sequence characteristics better

should be ordered according to the combined characteristics of ophiolites

it can be divided into ophiolite melange formation. The era of belonging to the Ordovician Silurian. The mafic rocks formed as a limited basin of olive tholeiitic magma limited separation after crystallization

has the characteristics of low calcium magnesium rich aluminum iron components

in the early stage of differentiation of small ultramafic rocks

provides space for the structure formation related in minerals. The late Caledonian movement

"thein situ" fold of ore-forming elements in place for further activation of migration and enrichment but also provides the conditions. The ultramafic rocks most strongly serpentinized and create favorable geological conditions for the formation of serpentinite ore deposits. At the same time

the Zaheba ophiolite formation reflects oceanic crust the formation of a new mode of transformation between evolution and continental crust growth

provides new information for the formation and evolution of the crust.
