    摘要:

    本文将我国锆矿划分为碱性花岗岩型、碱性杂岩型、伟晶岩型、风化壳残坡积型、滨海沉积型和河流冲积型,将锆矿预测类型划分为花岗岩型、伟晶岩型、滨海沉积型、河流冲积型、风化壳残坡积型。我国锆矿资源分布在内蒙古、海南、四川、广东等15个省(自治区),这4省(自治区)锆矿保有资源量达到全国总量的93.7%。我国锆矿形成于新元古代、晚古生代、中生代、新生代,主要形成于中生代和新生代。划分了14个锆矿成矿带,厘定出34个与锆矿有关的成矿系列,建立了我国锆矿成矿谱系。东南沿海的滨海沉积型和河流冲积型锆矿是将来锆矿找矿的重点。

    Abstract:

    This article divides China's zirconium deposits into alkaline granite type, alkaline complex type, pegmatite type, weathering crust residual slope deposit type, coastal sedimentary type, and river alluvial type. The predicted types of zirconium deposits are divided into the granite type, pegmatite type, coastal sedimentary type, river alluvial type, weathered crust and residual slope deposit type. China's zirconium ore resources are distributed in 15 provinces (autonomous regions) including Inner Mongolia, Hainan, Sichuan, and Guangdong, with zirconium ore reserves in these four provinces (autonomous regions) accounting for 93.7% of the national total. Based on the statistics, the metallogenic period of zirconium deposits in China is divided into Neoproterozoic, Late Paleozoic, Mesozoic, and Cenozoic. 14 zirconium metallogenic belts are divided. 34 Zirconium-related metallogenic series are determined and the metallogenic pedigree of zirconium deposits in China is established. The coastal sedimentary and river alluvial zirconium deposits along the southeast coast can be used as prospects for zirconium exploration.
