在广东某地区,广泛分布有含钴锂硬锰矿,它是“龙山系”和二迭纪地层风化形成的残坡积型及淋积型矿床。过去对这些矿床统称之为“钴土矿”。然而,经我们最近的工作证明,该区的“钴土矿”中的钴主要是赋存于锂硬锰矿中,因此,对这种“钻土矿”就有必要重新认识了。
In some areas of Guangdong, cobalt-rich lithium-manganese ore is widely distributed. It is a residual-slope sedimentary and deposit type mineralization formed by the “Longshan Series” and Permian stratigraphy weathering. These deposits in the past collectively referred to as “cobalt ore”. However, as our recent work has shown, the cobalt in the “cobaltite” of the area mainly occurs in lithium-manganese ore, so it is necessary to re-understand this kind of “diamond mine” .
