摘要
///The Xianghuapu tungsten deposit is the rare fluorite-scheelite-type deposit in southern Hunan Province. In the present contribution, rare earth elements in-situ analyses are performed by LA-ICP-MS on scheelite and calcite samples collected from the Xianghuapu deposit. The studies show that the Xianghuapu deposit is related to magmatic activity in origin, and the ore-forming fluid is transported under reducing conditions, after the crystallization of LREE-rich calcite and scheelite, calcite with flat-type REE patterns were subsequently precipitated. On the other hand, the inhomogeneity may also be affected by later fluid which pollutes the crystal face of some mineral grains.
