单矿物分选方法及其在构造地质研究中的意义──以磷灰石和锆石为例

SIGNAL MINERAL SEPARATE METHOD AND ITS SIGNIFICANCE IN GEOTECTONICS ──TAKING APATITE AND ZIRCON AS EXAMPLES

阐述了单矿物分选在构造地质研究中的意义。概述了单矿物分选的一般方法。重点研究了从盆地沉积岩中分离磷灰石和锆石的方法和技术。探讨了磷灰石在裂变径迹年龄测试中的重要性。

This paper is studying the method and the significance of separating signal mineral fromrock in tectonic-thermal evolution; and the authors discuss the method and techniques ofseparating apatite and zircon from rock, and the significance of fission-track dating of apatiteis discussed.
