| 中文摘要: |
| 贵州修文红黄铝土矿床位于黔中铝土矿成矿带，铝土矿体产于下石炭统九架炉组中部或中下部，产状与地层产状基本一致。矿石按自然类型可分为碎屑状、半土状、致密状三种，一水硬铝石为主要矿物，为沉积型铝土矿床。通过野外地质观察及资料综合分析，总结了红黄铝土矿地质特征及矿体的变化规律，矿体与含矿岩系的厚度变化呈正相关关系。区内铝土矿严格受地层岩性、构造、岩相古地理、古气候等控矿因素的制约。提出了该区铝土矿找矿标志。 |
| 英文摘要: |
| Honghuang bauxite deposit in Xiuwen located in bauxite metallogenic zone of central Guizhou，the orebody occurs in the middle or lower Jiujialu formation of lower Carboniferous Series，the occurrence is same as the formation occurrence.The minerals include clastic，semi-earthy and massive shape，the main mineral is diaspore the deposit is sedimentary bauxite deposit.By field observation and comprehensible analysis，the geologic characteristics of Honghuang bauxite deposit and changing regulation of orebody are summarized，the relation of orebody and ore-bearing rock thickness is positive.In the area, bauxite is restricted by stratum lithology，structure，lithofacies paleogeography，paleoclimate and other factors，then the prospecting indicators are pointed out. |
