分析了伊宁板块南北缘的沉积（变质）岩钕同位素组成，利用沉积岩中钕同位素模式年龄探讨塔里木板块、伊宁板块和准葛尔板块之间的关系．伊宁板块北缘阿拉套山脉西部沉积物物源区年龄约１．９Ｇａ东部沉积岩钕模式年龄０．９－１．４Ｇａ，表明伊宁板块与准葛尔板块碰撞造山作用，幔源物质的加入有关．伊宁板块南缘的志留系沉积物来自约２．５Ｇａ的物源区．
The neodymium isotopic compositions of sedimentary (metamorphic) rocks in the north and south of the Yining plate are analyzed. The relationship between the Tarim plate, the Yining plate and the Junggar plate is discussed based on the neodymium isotopic age of sedimentary rocks. The sedimentary provenance of the western Alashan Range in the northern margin of the Yining Plateau is about 1.9Ga in age and the neodymium model age of the eastern sedimentary rocks is 0.9-1.4Ga, indicating that the Yining plate collided with the Junggar plate orogeny and that the mantle-derived material Join about. The Silurian sediments on the southern margin of the Yining plate come from provenance areas of about 2.5Ga.
