The viscous remanent magnetization orientation technique is presented in which a present day component of magnetization is isolated during the progressive demagnetization of core material.
介绍了粘滞剩磁 (VRM)岩芯定向的原理和优点。
This paper analyzed the characteristics of remnant paleomagnetization in Dashen block of Xushen Gas Field in detail,utilizing viscous remnant magnetization to study the fracture orientation in volcanic rocks,making all the relevant trend-rose diagram for fractures,and intuitively reflecting the dominant direction of fracture development in statistics.
分析徐深气田达深区块营城组火山岩的剩磁特征,利用黏滞剩磁进行火山岩岩心构造裂缝的定向研究,制作相应井的裂缝走向玫瑰花图,从统计学角度直观反映裂缝发育的优势方向。
With modern multiple stratigraphic classification as the theoretical basis, the density, susceptibility and residual magnetization of regional lithostratigraphic formations as the research objects , and the Fisher grouping for maximum homogeneity as the mathematical means, the authors defined and determined physical stratigraphic boundaries of the stratigraphic column in Hebei Province.
以现代地层学多重划分为理论依据,以岩石地层单元组的密度、磁化率、剩余磁化强度及厚度加权算术平均值等物性参数为研究对象,以有序地质量最优分割方法为数学手段,进行河北省全区综合地层柱物理地层界线的厘定,并对其地质意义进行了初步讨论。
