| 中文摘要: |
| “贺州白”是我国白色大理石具有代表性的三个品种之一，贺州平桂区水井山矿区的大理石矿石材品种即属“贺州白”系列。本文通过野外调查与样品测试分析等手段，基本查明了水井山矿区大理石矿床的地质特征和成因。研究发现，矿体主体以层状产出，赋存于上泥盆统融县组地层，成因类型为热接触变质型。矿石主要由方解石组成，根据矿石类型，将石材品种分为“云团白”（岩性为白色、灰白色含暗色团块中粒大理岩），“红线白”（岩性为白色、灰白色含铁质红色色线中粒大理岩），“雪花白”（岩性为白色中细粒大理岩）三种。矿石作为石材其影响装饰性能的金属矿物含量不高、物理性能优良、放射水平极低、完整性较好、荒料率较高，是优质的饰面石材矿。 |
| 英文摘要: |
| “Hezhou White” is one of the three representative varieties of white marble in China. The marble from the Shuijingshan mining area, Pinggui District, Hezhou of Guagnxi, belongs to the "Hezhou white" series. This work attempted to clarify the geological characteristics of the marble deposit in the Shuijingshan mining area by means of field investigations and sample tests and analysis. Results show that the main orebody occurs in layers and is hosted in the Upper Devonian Rongxian Formation. Its genesis is of the thermal contact metamorphic type. The ore is mainly composed of calcite. According to the type of ore, stone varieties can be divided into three kinds which are “cloud white” (white, gray white marble containing dark mass), “red line white” (white, gray white medium grained marble with ferriferous red lines), and "snow white" (white medium-fine grained marble). This marble deposit is a high-quality ornamental stone mine with low metal mineral content, excellent physical properties, extremely low radiation level, good integrity and high rate of quarrystone. |
