摘要
地质作用过程持续时间的确定具有重要意义。前人已建立的地质定年方法 (同位素法、古生物法和古地磁法 )给出的是地质事件的“绝对年龄”或相对年代。但至今国内外尚缺乏有关地质作用持续时间的直接的测定方法。
Geological timing methods established(isotopic method, paleontologic method,paleomagnetic method)set the “absolute age” or relative era of certain time in the geological process.But there have been no direct methods to measure the time limits of geological processes whether abroad or domestically so far. The tectonic chemical timing method we discussed, here is a new method which fixed the approximate quantification of time limits in the tectonic geological processes.
