摘　　要：广绿玉又称为“广东绿”,被誉为“中国五大名石”之一。本文通过在广东广宁县某广绿玉矿的详查工作对广绿玉的地质特征和成矿机理进行了分析。研究认为,广宁县某广绿玉矿主要岩性为绢云母岩、绢英岩两种,属绢云质玉;广绿玉是由糜棱岩化花岗斑岩经过低温热液蚀变而成。Guanglyu jade is also known as"Guangdong green",and is one of the"five famous stones in China".This paper analyzed the geological features and metallogenic mechanism of Guanglyu jade based on the detailed investigation of a Guanglyu jade mine in Guangning County,Guangdong Province.The study showed that the main lithology of a Guanglyu jade mine in Guangning County is sericite chist and sericitolite,which means the mine belongs to sericite jade;Guanglyu jade is formed from mylonitized granite porphyry through low-temperature hydrothermal alteration.
