| 中文摘要: |
| 赣北下鞭山锡矿床位于江西省德安县境内,是长江中下游彭山锡多金属矿田内重要的锡矿床之一。本文对矿石中锡的赋存状态及锡石嵌布特征、嵌布粒度、解离性、生成温度等做了详细的分析研究,认为锡石矿化与硅化蚀变关系密切。文章概括了下鞭山锡矿床地质特征,分析了其控矿素和成因类型,指出了本矿床成因类型属气成-高中温热液构造蚀变岩型锡矿床。该矿区1000 m以下是寻找隐伏岩体外接触带矽卡岩型锡矿有利部位,区内发育典型的气热液期至热液期的各种蚀变矿化,深部存在热接触变质现象,表明深部找矿潜力较大。 |

| The Xiabianshan tin deposit in northern Jiangxi Province is located in De'an County, Jiangxi Province, and is one of the important tin deposits in the Pengshan tin polymetallic ore field in the middle and lower reaches of the Yangtze River. In this paper, the occurrence of tin in the ore and the embedded characteristics, the embedded size, the dissociation and the formation temperature are analyzed in detail. It is believed that the sillimanite mineralization is closely related to the silicification alteration. In this paper, the geological characteristics of the Xiabianshan tin deposit is summarized, its ore-controlling factor and genetic types are analyzed, and that the genetic type of the deposit belongs to the gas-high-middle temperature hydrothermal structural altered rock type tin deposit is pointed out. Below 1000m in the mining area is a favorable part for finding the skarn type tin deposit in the contact zone of the concealed rock mass. Various alteration mineralizations in the typical gas-hydrothermal stage to the hydrothermal stage are developed in the area, and thermal contact metamorphism in the deep part indicate the potential for deep ore discovery. |
