利用X射线荧光光谱仪(X-ray fluorescence spectrometer, 简写为XRF)对海南岛昌化江流域土壤样品和昌化江河口与邻近海域沉积物样品中的锆、钛元素进行了测试分析,并计算了样品中的锆、钛品位.研究结果表明,昌化江河口及其邻近海域沉积物中的锆、钛砂矿具有明显的异常富集;昌化江流域表层土壤中Zr和Ti呈含量变化大、高值相对集中分布的特点;主要母岩为大面积分布的花岗岩;炎热潮湿气候和河流的动力条件为母岩风化和含矿碎屑向海搬运的主要地质营力;沿岸显著的波浪和潮流作用及典型的砂砾质海岸为昌化江河口与邻近海域锆、钛砂矿的形成创造了有利条件.根据锆、钛品位计算结果圈定了南、北2个矿化远景区.

This paper analyzes Zr and Ti of the topsoil samples obtained from the drainage of the Changhua River and the sediments collected from the Changhua River Estuary and its adjacent sea area using X-ray Fluorescence Spectrometer (XRF). The grade of Zr and Ti was calculated. The results show that Zr and Ti are enriched distinctly in the sediments of the Changhua River Estuary and its adjacent sea area, and that Zr and Ti in the topsoils of drainage of the river are characterized by large range of content and the relative concentration of high values. The main host rocks are the large-scale distributed granite, whose wheathering and debris transportation to the sea could have been mainly driven by the torridity and humid weather and river conditions. The significant coastal wave and tidal flow and the typical sandy and gravelly coast may have created favorable conditions for the formation of placer of Zr and Ti of the Changhua River estuary and its adjacent waters. The two mineralization prospect areas are confirmed. Further, two mineralization prospect areas are distinguished in terms of the grade of Zr and Ti. It is concluded that the geological conditions such as extensive distribution of granites, the climate of torridity and humidity, river hydraulic forcing, prominent tide and wave and typical gritty coast are in favor of the formation of Zr and Ti placers.
