| 摘 要： | 辽宁北西向断裂构造发育,通常表现为由多条断裂组成的北西向断裂带,多被中基性岩脉充填。北西向断裂(带)在磁场上主要表现为负磁场带,构成一个完整的北西向磁性块体;重力场则处于布伽重力异常等值线疏密突变带上。北西向断裂(带)具有多期活动的特点,是一组控岩、控矿构造,对金矿的控制作用尤其明显。

| Abstract: | There are NW- trending fault structures in Liaoning, it is shown by which NW- trending fault belt composed of many faults is filled with intermediate basic veins. The NW- fault structures are a group of rock and ore-control ones, having controlled spacial distribution of a part of intermediate acidity rock body since early Proterozoic. Because of the character of poly-times activities, the NWtrending fault (belt) is most favourable to superposition and enrichment of gold deposits. Considering magnetic field, it is negative magnetic field belt forming an integrited NW- magnetic body. Its gravitational field is on a density suddenchange belt of Bouguer anomaly isopleth. Available information show that most of gold deposits in Liaonlng are controlled by NW- trending faults. So the study on occurrence, evolution, scale and characteristics is of importance to looking for gold deposits. |
