一、前言钒钡铜矿(Vesignieite)是1963年在我国陕西省某地寒武纪黑色岩系中发现的一种含Ba、Cu的钒酸盐矿物。寒武纪黑色岩系层位稳定,在我国南部和中部地区有广泛分布,西北地区也有出露。我国地质工作者对它进行了大量的工作,据查其中含数十种有工业价值的元素、百余种矿物,富集成种类繁多和规模不同的稀有、稀土及贵金属矿 I. Preface Vesignieite is a type of vanadate mineral containing Ba and Cu found in the Cambrian black rock series of a certain place in Shaanxi Province of China in 1963. The Cambrian black lithostratigraphic layers are stable and are widely distributed in the southern and central regions of our country and also exposed in the northwest. Geological workers in our country have carried out a great deal of work on it. According to the investigation, there are dozens of elements with industrial value and over a hundred kinds of minerals, which are enriched into rare, rare earth and precious metal mines of various types and sizes
