Abstract

Abstract: Seismological interpretation revealed that basalts are overlain by rhyolite in the Halahatang area, Northern Tarim, Northwest China. The overlying rhyolite is dated by SIMS zircon U-Pb method, yielding a precise concordia age of 287.3 ±2.0 Ma, which limits the latest eruption age of the underlying basalt and reveals that the eruption age of the main pulse of the Tarim flood basalt is before 287 Ma, not ~275 Ma.

Key words: Tarim, flood basalt, large igneous province (LIP), rhyolite, zircon U-Pb age

摘要： 塔里木北部哈拉哈塘地区存在流纹岩覆盖于玄武岩之上的迭置关系。对上层流纹岩采用SIMS锆石U-Pb 法精确测定其年龄为 287.3 ±2.0 Ma。该年龄限定该区玄武岩的喷发时代不晚于 287 Ma,证明塔里木溢流玄武岩的主喷发期应不晚于 287 Ma,而非前人提出的大约 275 Ma。
