摘      要：Hogbomite,a rare exotic mineral,is found to be associated with the vanadiferous-titaniferous （V-Ti） bearing magnetite bands at Bhakatarhalli,Nuggihaifi greenstone belt,western Dharwar Craton,*** report on a second occurrence of hogbomite from the Dharwar craton in Karnataka,which is the sixth documented occurrence of this mineral from *** evaluate the chemical characteristics of hogbomite and associated Fe-Ti-minerals in an attempt to identify its formation as a primary hydrothermal mineral in a metamorphosed magnetite *** report here the presence of hogbomite as a complex oxide of Fe,Mg,Al and Ti with accessory of Zn,V and *** studies suggest the （V-Ti） bearing magnetite （Mt） contain spinel,hogbomite,chlorite,martite,ilmenite （Ⅱ） and minor amounts of *** hogbomite displays euhedral to subhedral textures,and is up to 250 μm along the grain boundaries of magnetite and *** the samples studied,hogbomite is prismatic,irregular and elongated in *** genesis of hogbomite in veins between magnetite and ilmenite implies its precipitation from fluids without involving complicated *** models were proposed for the formation of hogbomite; however,the subject is still debatable.
