摘      要：正The Late Paleozoic volcanic rocks in western Tianshan Mountains （Central Asia） formed the strata up to 10000m in an area of large than 30000km2. These volcanic rocks distribute in TAS plot continuously from basalt, basaltic trachyandesite, trachyandesite, trachyte, to rhyolite. The zircon SHRIMP dating shows that the zircons from basalts and trachy-andesites vary between 299
