摘要
方法利用微量元素丰度值变化规律与测井资料相配合，对东胜堡－静安堡潜山带内幕地层进行对比。目的解决其潜山带岩性识别难度大．地层对比困难的问题。结果以微量元素集聚变化的特征为主，结合岩性组合和斯伦贝谢测井资料，建立了两个标志层，在此基础上，将潜山带地层进行了对比，并自下而上划分了七个岩性段。结论采用本文方法进行潜山带内幕地层对比是可行的，而且效果较理想．并为在变质岩中进行地层对比与岩性划分提供了新的途径。
Method Stratigraphic correlation inside buried hil of Dongshengpu-Jing'anpu was carried out by combining abundance changement law of minor elements and log data. Purpose To solve the problems of lithology identification in buried hill and stratigraphic correlation.Result Based on characteristic of accumulation changement of minor elements, combining with lithological association and SCHIUMBERGER data, two guiding beds were set up.Stratigraphic correlation in buried hill was carried out on this basis. Seven lithology sections were divided in ascending order. Conclusion it is feasible to correlate the stratigraphy inside buried hill with this method. The result is ideal. It provides a new way for stratigraphic correlation and lithology determination in metamorphic rocks.
