| 中文摘要: |
| 本文旨在燕山岩带作决策模拟的基础上进一步缩小预测隐伏基性一超基性岩体的耙区。通过选择能充分表征预测岩体的航磁异常一次标志,组合标志构成多个变量作多元统计分析,提取与预测岩体密切相关的信息,圈定岩体异常并进行分类。从而建立本区基性超基性岩体的地质地球物理模式以及评价其找矿意义。 |
| 英文摘要: |
| This paper is aimed at reducing target area for searching blind basic-ultrabasic intrusives on the basis of characteristic analysis. The preliminary magnetic marks of the predicted can be characterized by selection. Association of marks produce variables for multi-element analysis by which informations closely related to the predicted are extracted and the magnetic anomlies of the selected intrusives are classified. Therefore the geological and geophysical model of Yanshan basic-ultrabasic rock belt,which is of significance for evaluation and ore searching, is established. |
