【摘要】 研究了形成风化型混合粘土矿的原岩、风化壳矿石和提取产品的稀土配分，它们不具有继承性。从１１３个矿样所提取的产品稀土配分相关分析，得出钆断效应和各半正相关性，且主要以轻稀土配分型为主占７７．９％，富钇和富铈配分型很少，分别仅占４．４％和１．８％。重稀土为主且赋存于易风化矿物的原岩易形成富钇配分型稀土矿。更多还原

【Abstract】 The rare earth distribution patterns in the original rock of formative weathering type complex clay ore, weathering ore and extracted product were studied and their distribution patterns don’t have inheritance. A gadolinium broken effect and a half plus relation were obtained through relation analysis of 113 rare earth product distribution patterns, and the light rare earth type distribution patterns are 77. 9%, yttrium rich and cerium rich type distribution patterns are very low, they are 4. 4% and 1. 8% respectively. The original rock of easily weathering minerals that mainly contains heavy rare earth elements easily forms rare earth ore of yttrium rich type distribution pattern.更多还原
