浙江泰顺洋滨斑岩锡矿成矿母岩为黄玉斑岩类岩脉，长约２ｋｍ，宽２－２０ｍ，岩性可分黄玉钾长花岗斑岩、黄玉二长花岗斑岩和黄英斑岩三种。黄玉含量占１０％－２０％，具火成斑状结构。岩石为强过铝质（Ａ／ＮＫＣ＝１．５７４－１２．９４），高Ｆ／Ｃｌ值（１４６－３０３），高Ｒｂ／Ｓｒ值（５－１２２），高的不相容元素丰度（Ｓｎ＝３１３×１０－６－１０４２×１０－６）而相容元素丰度较低（Ｓｒ＝１０×１０－６－２８×１０－６），稀土配分呈海鸥型，成因上应是Ｓ型含锡斑岩。
Zhejiang Taishun Yangbin porphyry tin ore metallogenic rock is a yellow jade porphyry dyke, about 2km long, 2-20m wide, lithology can be divided into topaz gold granite porphyry, topaz granite porphyry and Huang Ying three kinds of porphyry. Topaz content of 10% -20%, with a fire into a patchy structure. The rocks are stronger than aluminum (A / NKC = 1.574-12.94), high F / Cl (146-303), high Rb / Sr (5-122), high abundance of incompatible elements (Sn = 313 × 10-6-1042 × 10-6) and low abundance of compatible elements (Sr = 10 × 10-6-28 × 10-6). The distribution of rare earth elements is seagull, and the genesis should be S Type containing tin porphyry.
