陕西铜川-韩城铝土矿带矿床地质特征及成矿规律

The Geological Characteristics and Metallogenic Regulation of Hancheng-Tongchuan Bauxite Belt in Shaanxi Province, China

铜（川）-韩（城）铝土矿带位于陕西中部，已发现铝土矿床（点）数十处，探获铝土矿资源量1000多万t。笔者论述了矿带中主要矿区和矿体的地质特征，从控矿因素和成矿条件等方面分析了铝土矿成矿规律，提出进一步加强岩相古地理研究是该区扩大勘查成果的有效手段。

Several ten bauxite deposits and 10 millions tons resource have been found in Tongchuan- Hancheng bauxite belt in central Shaanxi province. Based on the geological characteristics of typical bauxite districts and deposits, the metallogenic conditions and regulation are discussed in the paper. It is put forward that enhancing the research of lithofacies is necessary toget new discovery in the district.
