| 摘 要： | 通过虎林石青山采石场角闪花岗闪长岩的锆石U-Pb LA-ICPMS 年龄测定，确定了虎林岩体形成于118 Ma 的早白垩世晚期。根据该岩体的岩石学和地球化学特征及区域构造演化研究资料，认为虎林岩体的形成与太平洋板块的俯冲作用有关。

| Abstract: | A new zircon LA--ICPMS U--Pb data of hornblende-bearing granodiorite from Shiqingshan quarry in Hulin revealed that the Hulin Pluton was emplaced during Early Cretaceous ( 118 Ma) ． Petrography and geochemistry of the Pluton and geological evidence of regional tectonic evolution suggest that the formation of Hulin Pluton was related to the subduction of the Pacific Plate． |
