摘要
在阐述了黔北务—正—道地区铝土矿成矿地质背景和成矿地质特征的基础上,总结了该区铝土矿的11个找矿标志:层位标志、底板岩性标志、含矿层标志、古侵蚀间断面标志、褶皱构造标志、地貌标志、植被标志、铝土矿标志、伴生矿产标志、脱硅、排铁标志、民采标志,进而初步建立了该区铝土矿的四个典型找矿模式:"瓦厂坪模式"、"新木—晏溪模式"、"新民模式"、"三清庙模式"。
Based on geologic and ore-forming background and bauxite deposite characteristics in Wu-Zheng-Dao area in north Guizhou,the article summarizes 11 indicators of bauxite deposit in this area.They are strata indicator,floor lithological indicator,ore-bearing strata indicator,palaeoerosion discontinuity type indicator,fold structure indicator,geomorphologic indicator,vegetation indicator,bauxite indicator,associated minerals indicator,desiliconization deferrization indicator and non-government exploration indicator.It also establishes 4 typical prospecting models for bauxite deposits in this area,including Wachangping model,Xinmu-Yanxi model,Xinmin model,Sanqingmiao model.
