视密度填图及其应用

视密度填图有助于重力测量数据的解释,在覆盖区,视密度图可作为岩石填图的有意义的参考资料。作者设计了空间域矩阵计算视密度的方法,通过模型试算,取得了高分辨率的视密度图;并且在钢陵地区实际应用表明,视密度图提供了地层密度分布的真实情况,在划分岩性、圈定岩体等方面也能起一定作用。

APPARENT DENSITY MAPPNG AND ITS APPLICATION

The apparent density mapping is of some help to the interpretation ofgravity data survey and, in covered areas, may serve as valuable reference datafor rock mapping. The anthor has designed an apparent density method forspace domain matrix calculation and, through tentative calculation by meansof the model, obtained an apparent density map with high resolution power.Its practical application in Tongling area shows that the apparent density mapreflects real condition of stratigraphic density distribution and thus can playa certain role in division of Iithologic cbaracters and delineation of intrusivebodies.
