福建上杭盆地中生代火山岩首次发现开来石

Kemmlitzite Discovered First from the Mesozoic Volcanic Rocks in the Shanghang Basin, Fujian Province

在１：５万上杭幅重砂野外调查中，在上杭盆地中生代火山岩河系中首次发现开来石。经中国地质大学Ｘ光单晶粉晶分析、桂林有色金属地质研究所电子探针成分分析结果，均与国外有关文献中的开来石相一致。是我省首次发现的含砷稀土矿物。它为在该区中生代火山岩中寻找稀土资源提供新的线索。此外该矿物常与黄金、辰砂等相伴生，笔者初步认为可以根据伴生金的相关元素Ａｓ开来石组合寻找金，是本区很值得注意的一种寻找金的方法。

The paper reports on the kemmlitzite which was first discovered in the river system of Mesozoic volcanic terrain in the Shanghang Basin of Northern Fujian. The kemmlitzite is one of the arsenic-bearing rare-earth minerals first found in Fujian Province,which is often associated with gold and cinnabarite.However,it is a new clue of prospecting rare-earth mineral resources in the Mesozoic volcanic rock of the region.And according to the mineral association of arsenic and kemmlitzite with gold,it is possible to prospect a gold in the area.
