内蒙古赤峰地区重磁特征及其地质意义

高精度的磁测结果显示，内蒙古赤峰北部岩浆岩发育地区磁场特征具有明显的规律。对其进行一系列常规数据、小波变换等处理，有效地分离了异常场，发现不同期次的火山岩和侵入岩由于其来源不同，表现出不同的磁场特征。进一步与重力资料对比分析，确定了火成岩的属性，进而推演出研究区火成岩的空间展布和属性特征，表现为西部由浅表火山岩和深成侵入岩组成，而中东部深浅成的复式侵入岩体占主导。该研究也证明高精度磁法勘探和新的处理技术是覆盖区火成岩隐伏体研究的有效途径。

Gravity and magnetic features and geologic significance in the Chifeng area, Inner Mongolia, China. Geological Bulletin of China

High precision magnetic study shows that distinct rules exist in the magnetic features of northern Chifeng area, Inner Mongolia. Based on a series of conventional data processing and wavelet transformation, anomalous field is separated, it is suggested that there are different origins of volcanic and intrusive rocks of different phases, which displays different magnetic feature. Through further comparison with gravity data, the properties of igneous rocks are identified, furthermore, spatial distribution and properties of the rocks are deduced. In the western part, it′s mainly composed of shallow surface igneous rock and deep intrusive rock, while in the middle-east part, it′s dominated by intrusive rock of both shallow and deep origin.
