河北某地铂矿床(矿化),经我们配合某地质队四年来的野外、室内工作,初步认为该矿床(矿化)类型应属“前寒武纪超变质铂矿床”.含矿岩石为榴长-斜长石岩.铂族元素均以单矿物形式存在,选别性能较好.铂钯矿化不均匀,铂钯最富可达3克/吨以上,一般为O.3～O.5克/吨,铜平均品位为O.2～O.3%.该矿化类型国内尚很少报导.本区与格陵兰西部的一个含铂超变质岩(斜长岩)铬铁矿矿床有相似之处,唯本区无铬铁矿产出.河北某地前寒武纪超变质岩铂矿床(矿
A certain platinum deposit (mineralization) in Hebei Province has been tentatively considered to belong to the “Precambrian ultra-metamorphic platinum deposit” by cooperating with the field work and indoor work of a geological team for four years. The ore-bearing rocks are Palygorskite plagioclase.The platinum group elements are all existed in the form of single mineral, and the sorting performance is better.The platinum-palladium mineralization is non-uniform, the most abundant platinum-palladium is more than 3 g / t, usually O.3 ~ O .5 g / t, average grade of copper is O.2 ~ 0.3% .Mineralization of this mineralization is seldom reported domestically in this area and a platinum-bearing ultrametamorphic (plagioclase) chromite deposit in western Greenland There are similarities, only the area without chromite output.Pre-Cambrian, a super-metamorphic platinum deposit in Hebei
