摘要
利用高精度重磁资料解释盆地隐伏岩体,认为武功—赵村镇磁异常为中酸性侵入岩引起,且为重磁同源,磁性体范围约100km^2,磁性体顶面埋深在4000m左右。并以此为渭河盆地氦气成因、储存和开发利用提供深部地球物理依据。
Interpretation of high precision gravity and magnetic data for concealed rocks in the weihe basin indicates that the magnetic anomalies defined in Yizhaocun town of Wugong county is given rise to intermediate-acid intrusive rocks.The magnetic range is about 100 km2 and featured in gravity and magnetic homology showing concealed depth about 4,000 meters of the top surface of the magnetic bodies,which would be a deep geophysical basis for genesis,reservation and development of helium in the Weihe basin.
