| 摘 要： | 大厂矿田的地球物理场,宏观特征表现为重力低与环形磁异常配套,它是高侵位隐伏花岗岩及其热变质带组成的矿田的标志.其微观特征表现为重力外凸与叠加磁异常或激电异常配套,这是不同类型、不同剥蚀水平的矿床的标志.研究这些标志,对成矿区带上寻找隐伏矿床是有意义的.

CHARACTERISTICS OF GEOPHYSICAL FIELD OVER THE DACHANG TIN-POLYMETALLIC ORE FIELD AND THEIR SIGNIFICANCE IN ORE-PROSPECTING |

| Abstract: | The geophysical field of the Dachang ore field displays gravity low combi-ned with ringed magnetic anomalies as its macroscopic character, which is anindication of the ore fie1d composed of concealed granite of high-level empla-cement and its thermal metamorphic zone; microcosmically, this field showsgravity outward convex combined with superimposed magnetic anomalies or IPanomalies, which is an indicator for ore deposits of different types and atdiverse denudation levels. An investigation of these indicators seems to be ofsignificance in looking for concealed ore deposits in a metallogenic area or belt. |
