赣西北与粤北地区辉绿岩物性对比研究

Northwest of jiangxi and north guangdong region diabase property contrast research

就不同区域同种岩性的物性规律是否一致的问题,本文研究了两区域的辉绿岩物性特征,统计结果显示赣西北辉绿岩比粤北辉绿岩电阻率低两个数量级、极化率低3%左右、磁化率高一个数量级、密度大0.35g/cm3。经分析辉绿岩化学成分、所处地质环境、岩石年龄等情况存在差异。所以不可随意套用探测区域之外岩性的物性。

The issue is whether the same kinds of rock physical properties law are unanimous on the same kand of different areas,This paper studies the diabase physical characteristics of the two regions,Statistics showed that northwestern Jiangxi diabase resistivity than northwestern guangdong diabase lower two orders of magnitude、Polarization rate is lawer about 3%、Magnetic susceptibility is higher a ordrs of magnitude、Density is lowe 0.35g/cm3. After analyzing the chemical composition of diabase、The geological environment and rock Age etc are differences. Conclusions is that it is not free to apply outside the detection area lithological properties.
