| 中文摘要: |
| 贵州省务(川)正(安)道(真)地区是贵州省重要的铝土矿资源产地,铝土矿矿点多,含矿岩系分布广,储藏量大,找矿前景好。近年,贵州省有色、地矿等地勘单位通过地表调查、勘查,已发现矿床(点)26处,探明大型矿床3个,中型矿床1个,提交332+333资源量1.3亿t。文章从该地区铝土矿的形成环境、含矿岩系变化情况及与其顶底板岩性之间的关系,探讨该区铝土矿的找矿方法。 |
| 英文摘要: |
| Wuchuan-Zheng’an-Daozhen area is an important origin for bauxite resources in Guizhou province. There are a good many bauxite occurrences and large reserves of bauxite in this area, furthermore, ore-hosted strata are widely distributed which reflecting a good prospect for bauxite, and therefore aroused much attention among geological prospecting units in the province. In recent years, several geological prospecting units in Guizhou province including the nonferrous geological exploration bureau as well as geological and mineral resources bureau have discovered 26 bauxite deposits or occurrences, moreover, 3 large-size and 1 middle-size deposits have been proved, total amount of 332+333 reserves ascertained reached 130 million tons. According to the characteristics of the terrains in this area as deeply dissected, with relative highness differences and the ore-hosted strata outcropped on the crust surface are partly overlain by collapsed limestone severely, this thesis discusses the ore-exploration methods for bauxite by analyzing the ore-formation environment for bauxite, the changes of ore-hosted strata, and the relationship between roof and floor lithologic characters of the ore-hosted strata in this area. |
