陕西省冶金局渭北地质斟探队第三分队,在陕北府谷地区沿黄河一带,找到了一个大铝土矿床。矿体产于中石炭纪地层之内,相当于我国东北及华北的G层铝土矿。矿体沿长约有40华里左右,在该区沿黄河畔从府符县城至清水河一带均有矿体露头出现,矿体为似层状或透镜状体,一般厚度为1公尺至2公尺,最大厚度可达10余公尺。根据目前部分化验分析结果统计,含Al_2O_3一般为40—65％,其中含Al_2O_3大于
Shaanxi Provincial Metallurgical Bureau Weibei Geological Pouring Team third unit, Fugu in northern Shaanxi area along the Yellow River, found a large bauxite deposits. The ore body is produced in the Middle Carboniferous strata, which is equivalent to the G-layer bauxite in Northeast and North China. The ore body is about 40-li in length. There are ore-body outcrops in the area along the Yellow River from Fufo county to Qingshuihe area. The ore body is stratified or lenticular in shape with a typical thickness of 1 to 2 Meters, the maximum thickness of up to 10 meters. According to the statistics of some of the present laboratory analysis results, the content of Al 2 O 3 is generally 40-65%, and the content of Al 2 O 3 is greater than
