Abstract:Laomuzhushi Ta-Nb ore field is located on the north side of the Dabie Mountains, in the core of Qinling-Dabie organic belt where east Qinling fold belt of Qinling fold system extends eastward. Here, a Ta-Nb deposit is found in K-feldspar leucogranulitite of the lower Dahongkou formation . The main Nb-and Ta-bearing minerals are niobite, ilmenorutile and titanium-rich hematite. The Ta-Nb ores there are characterized by fine grains and high level of dispersion. Laomuzhushi Ta-Nb deposit is metamorphic origin . In this paper, our focus is on the deposit geological characteristics and the ore-forming and ore-controlling factors, which are indicative of similar Ta-Nb deposits and other rare metal deposits in South Henan.
