Abstract :

Se_ chahun iron deposit (Anomaly No.10) is located in 30km North-East Choghart iron mine in yazd Province lran.This deposit is in the Central IrarZone in the Volcano- Sedimentary of infracambrian-lowercambrian rocks lr.

this work have been studied Petrography ,Petrology ,mineralography,geochemistry of are ond Country rocks and mainly genesis of ore

On the basis of Petrographic studies and modal ,geochemical anc normative classification ,ingneous rocks are: granite,diorite , gabrodiorite anc Volcano - Sedimentary rocks are consist of : tuff , Porfyrite,Aleurolite anc�limestone .The latter group Particulary those which are country rocks of or

are extremly under The influence of metamorphism and metasomatisrr, .phenomena

01 Using of The discriminate diagrams of I and S types, granites and comparnng Characteristics of These two types , granites of Se-Chahun districi

. are concluded to be from the ! ype

Interpretation the two dimensional Harker and Spider diagrams , it Seems that there is a genetic relationship between diorites and granites, of this regior

via magmatical differentiation .Otherwise There is no relation between igneou5

9 kalkaline but from the Point of tectonical Setting of them ar ا! rocks are extensional and rift ,these matters are due to a crost assimiliation of primary

. alkaline magma with crust rocks of Path

Statistical studies of geochemical data , Show that Fe2o3 have Positive

correlation with Co, cr,v and have a negative correlation with P2o5 ,sio2, A12o3, Na2o ,H2o and REE.Furthermore P2o5 with cao and REE have a high correlation.

Se-Chahum iron deposit (Anomaly No . 10) contain Three ore bodies. Or

6 The Surface of that are Chosen 14 exploration Profiles .They ar approximately vertical on the Length of the masses. On this Profiles have .digged 41 wells , totally 3616 meters excavation

11009000tons.Averag ,content iron is whole anomaly store in three masses equal 51.17 Percent and Phosphorus is 0.09 Percent

A long with magnetite exsists the other minerals , for example martite

9 During Prosses martitizasion) hematite, goethite and low quantity minerals ar( rich titanium , for example ,llmenite titanomagnetite, chalcopyrite , Pyrite ، Nonmetal minerals include chlorite actinolite , teremolite , epidote , feldspar. ... " apatite , talk , esphen , rutile , quartz

The ore deposit is a V-Ti bearing ore that is formed

3 magnetite.Furthermore in the east elevation of ore mass ,mineralization. hematite - specularite in the shape of stratabound and syngenetic Ore genesis of Se-chahun is a submarine volcanic - exhalativewhich havE been under the influence of metamorphism contact and metasomatism anc�have formed magnetite and other metasomatic minerals in this Process.
