前言 江西南部某黑钨矿床,主要是由黑钨矿云英岩细脉浸染型的中型黑钨矿床。成因属类型气化——高温热液矿床。 矿床产于花崮岩岩基边缘或小型花岗岩岩株顶部裂隙发育的部位。矿体为含矿石英细脉及各类云英岩化蚀变围岩组成的云英细脉带中。该类矿床有二十余个矿带,最大的延长600米,宽度自十几米到百余米不等,工业矿化深度在岩体接触界面以下20～60米。矿石为细脉浸染状,含矿石英细脉一般短小,延长仅2～3米,脉宽1～3厘米,但也有个别较大者。矿化云英岩中,黑钨矿呈浸染状。
Preface A wolframite deposit in the south of Jiangxi Province is mainly composed of medium-sized wolframite disseminated by veins of veins and wolframite. Genesis genus type gasification - high temperature hydrothermal deposit. The deposit is located at the edge of the sag of the sagite rock or the site where the top of the small granite rock strain develops. The orebody is a veins of quartz veins composed of ore-bearing quartz veins and various types of micritic alteration rocks. This type of deposit has more than twenty ore belts, the largest extension of 600 meters, width from ten meters to a hundred meters, industrial mineralization depth below the rock contact interface of 20 to 60 meters. Ore disseminated veins, ore-bearing quartz veins generally short, extended only 2 to 3 meters, pulse width of 1 to 3 cm, but there are some larger. In the mineralized dolomite, the wolframite is disseminated.
