| 中文摘要: |
| 冀北承德—张家口一带钒钛磁铁矿资源丰富，各类型矿床主要赋存于沿红石砬—大庙—娘娘庙东西向深断裂及两侧侵入的基性—超基性岩体中。该基性—超基性岩带主要有大庙斜长杂岩体、头沟斜长岩体、红石砬辉长岩体、铁马辉石角闪石岩体、高寺台超基性岩体、张营子超基性岩体等数十个岩体组成。这些岩体为钒钛磁铁矿、铁磷铬铁矿、铂钯矿的成矿母岩，并且都能够产生强度较大的磁异常。本文通过综合分析本区典型钒钛磁铁矿床产生的磁异常特征，包括航磁异常和地磁异常，根据磁异常特征的不同，总结该区多种磁铁矿床引起磁异常特征。列举磁异常成功找矿勘查案例，可为其他此类型磁异常找矿提供借鉴。 |
| 英文摘要: |
| There are abundant vanadium-titanium-magnetite resources in Chengde-Zhangjiakou area of north.ern Hebei Province, and various types of deposits mainly occur in the basic-ultrabasic rock mass along the HongshiLa -Damiao-Niangmiao deep faults and intrusions on both sides. The basic-ultrabasic rock belt mainly consists ofdozens of rock masses, such as Damiao plagioclase complex, Tougou plagioclase complex, Hongshila gabbro com.plex, Tiemapyroxene amphibolite complex, Gaositai ultrabasic complex and Zhangyingzi ultrabasic complex. Theserock masses are the ore-forming parent rocks of vanadium-titanium-magnetite, ferro-phosphochromite and platinum-palladium, and all of them can produce magnetic anomalies with high intensity. In this paper, the charac.teristics of magnetic anomalies caused by typical vanadium-titanium magnet deposits in this area, including aero.magnetic anomalies and geomagnetic anomalies, are summarized according to the different characteristics of mag.netic anomalies. The successful prospecting cases of magnetic anomaly are listed to provide reference experiencefor other types of magnetic anomaly prospecting. |
