用ICP MS测定了黔西南烂泥沟、丫他卡林型金矿床石英流体包裹体中的稀土元素含量 .研究表明 ,流体包裹体中的∑REE含量 ,以成矿晚期石英 方解石阶段最高 ,为 84 .17× 10 - 6 ;成矿期石英 黄铁矿 毒砂阶段较低 ,为 (2 .6 7～ 13.12 )× 10 - 6 .稀土配分模式显示LREE相对富集 ,HREE亏损 .从成矿期到成矿晚期 ,成矿流体都具有弱Ce负异常 ;Eu异常则不同 ,成矿晚期具有弱Eu负异常 ;而成矿期则显示弱Eu负异常到弱正异常 .
The contents of rare earth elements in the quartz fluid inclusions of the Lannigou and Yatarika gold deposits in southwestern Guizhou Province were measured by ICP MS.The results show that the content of ΣREE in the fluid inclusions reaches the highest in the late stage of mineralization with quartz calcite at 84 .17 × 10 - 6; The quartz pyrite arsenite stage is low (2.67 ~ 13.12) × 10 - 6 in the mineralization stage.The REE distribution pattern shows that the LREE is relatively enriched and the HREE is depleted.From the stage of mineralization In the late stage of metallogenesis, the ore-forming fluids all have the weak negative anomaly of Ce, the Eu anomalies are different, the late stage of metallogenesis has a weak Eu anomaly, and the mineralization stage shows the weak Eu anomaly to the weak positive anomaly.
