胶东地区区域岩石物性参数的地质应用

Geological Application of Physical Property Parameters in Regional Jiaodong Area

摘要:

不同区域岩石类型标本测定的物性参数，除作基础资料供区域地质及区域地球物理研究使用外，还可以结合地质资料解决某些地质问题。文中利用胶东东部188件样品和胶东西部80件样品的5种物性参数:K(磁化率)，Jr(剩磁)，σ(密度)，ρ(电阻率)，η(极化率)，采用判别分析方法，解决胶东东部和西部岩体划分对比问题，并依据物性参数进行聚类分析，划分不同母体。

Abstract:

Physical property parameters determined in different rock samples can not only be used in regional geology and geophysical study, but also can be used to solute some geological problems. By using 5 physical parameters, such as K(magnetic capacity)，Jr(remanence)，σ(density)，ρ(electrical resistivity) and η(chargeability) of 188 samples gained in east part of Jiaodong area and 80 samples gained in west part of Jiaodong area, and using distinguishing method, rock division between east and west part of Jiaodong area is soluted. According to physical parameters, clustering analysis is carried out in this paper, and different matrix is divided as well.
