Research On Vanadium Titanium Magnetite Ore Forming Geological Conditions And Metallogenic Regularity Of Miyi County Anning Village

The Anning village is locate at the northernmost of Hongge ore fields which is one of the four main vanadium titanium magnetite ore fields in panxi region.This article through to the mining area of regional geology,mining area geology and ore deposit geology and ore features comprehensive account of metallogenic conditions and metallogenic rules of the ore body are simply analyzed.Here are some conclusions:1.The Anning village of vanadium titanium magnetite of ore-bearing bed,for it all in Kangding group metamorphic rock intrusion formed by crystallization differentiation.Its bottom is quartzite,leptynite,marble and amphibolite.The roof for the deposit is amphibolite in lower proterozoic.The time of instruction is early than Emeishan ba-salt,but later than Kangding group.2.The deposit ore central can be divides into two classes for before and latter mineralize.The former is Anninghe fracture and Xigeda fracture.The latter is primary flow structure of the ore bodies and the late formed fracture.3.The structure of the ore mainly includes dissemination structure,dense block structure and the banded structure,etc.The main texture includes granular Mosaic texture,poikilitic texture,intersertal texture,etc.The main metal mineral in the ore is iron titanium oxide,a small amount of sulfide and gangue minerals are mainly silicate minerals,a small amount of phosphate minerals.4.The main cause of deposit is the ore bearing basic-ultrabasic magma began to invading from the Anlinghe fracture and Xigeda fracture formation period,magma crystallization differentiation,faulting controlling the direction of magmatic activity.While magma to capacity expansion of the magma chamber,due to the effects of ambient pressure and temperature of the surrounding rock,forced condensation no longer extension of magma differentiation,the first differentiation of two different basic and Ultra basic,cooling crystallization,silicate minerals are pyroxene,olivine crystals and sinking first stacked,soda-lime silicate surface.The ingredient continuous change with magma crystallization differentiation,the concentration for the different minerals,volatile components increases,apatite floats to gabbros phase.The spaces between the silicate mineral particles are filled by metal components.These actions make the better prosodic structure and different deposits formed.5.The prospecting direction for this area.The anninghe fault zone is a favorable area for mineralization,so affirm the location,nature,the fault zone and the movement,migration,etc in activities of different tectonic is quite important.Secondly,the mainly anomaly of vanadium titanium magnetite is magnetic,so we should pay attention to the aeromagnetic or magnetic anomaly area.The last caught our attention is the baste and ultra basic rock or basic-ultra basic rock which discovered before.We should pay attention to the large scale,good differentiation,vanadium or titanium iron high background values of rock mass.
