| 摘 要： | 依据冀北地区1:20万区域重力调查成果,阐述了区域重力调查在冀西北地区侵入岩体勘探中的应用.在充分研究该区重力异常的基础上,圈定出了几个重要岩体,并据此总结归纳出定性解释岩浆岩体及产状的重磁场标志,建立了该区几种侵入岩体的地质-地球物理模型,且进一步对该区岩浆岩的分布特征形成了新的认识.

| Abstract: | According to the 1:200000 regional gravity data in northwest Hebei, this paper deals with the application of regional gravity survey to the exploration of intrusive bodies in northwest Hebei. Based on a detailed study of the gravity anomalies in this area, the authors delineated several important rock bodies and, on such a basis, generalized the gravity and magnetic field marks for qualitative interpretation of magmatic rocks and their modes of occurrence. In addition, geological-geophysical models for several kinds of intrusive bodies were formulated, and new understanding concerning the distribution characteristics of the magmatic rocks in this area was put forward. |
