对河南省方城北部正长岩岩体进行稀有金属、稀土元素含矿性研究，采集于岩体中14?件具块状构造的新鲜岩石样品揭示了良好的?Rb、Zr、Nb、LREE（轻稀土）矿化信息。2?件样品的?Rb?含量（532.0×10-6?和?974.9×10-6）高于碱性花岗岩及花岗伟晶岩型Rb矿床边界品位的样品，12?件样品的?Zr?含量（465×10-6～1545×10-6）超过砂矿型Zr矿床边界品位值，11?件样品的?Nb?含量（95.2×10-6～376.7×10-6）高于碱性花岗岩型?Nb、Ta?矿床的边界品位值，11?件样品中?LREEO（轻稀土氧化物）含量（553.6×10-6～920.9×10-6）高于离子吸附型?LREEO（轻稀土氧化物）矿床的边界品位值。这些与正长岩岩体相关的稀有金属、稀土元素矿化信息为进一步的找矿勘探提供了重要线索。
