广西都庞岭地区南竹河锡矿床产于花岗岩体的内外接触带,以脉状为主,受断裂构造控制.通过地表与深部构造相结合的研究,发现该矿床矿脉在时空分布上具有"线性递变不等距"分布规律,即矿脉在横向分布和纵向分布上分别表现为矿脉组间距、矿脉组内脉间距及矿脉段间距均具有线性递增规律.这种规律在南岭地区的九毛-六秀、芙蓉等锡矿田(床)也有表现.另外,对这种规律产生的构造原因也进行了初步探讨.

The Nanzhuhe tin deposit in Dupangling area is developed in the endo-and exo-contact zones of a granite body. The mineralized veins are mainly controlled by the fracture syetem. Through a combined study of both ground surface and deep structures,this paper found that the mineralized veins of this deposit have a "increasing distance pattern" in space distribution:namely,all the intervals between mineralized veins within a vein group in the crosswise direction,the intervals between vein groups in the crosswise direction,and the intervals between the mineralized blocks within a mine district in the longitudinal direction,have a regularity of progressively increasing distance pattern. This regularity is also valid for the Furong and Jiumao-Liuxiu tin ore-fields etc. in the Nanling metallogenic belt and of significance for exploration work in the study area and the Nanling Mountains region as a whole. The relation of this regularity with fracture structure development is also discussed in this paper.
