The ore ' s mineral component is simple , and its main association of minerals are leucocratic sphalerite - galenite ? iopsite ( epidot , chlorite ) . leucoratic sphalerite and diopsite are the guide minerals in the ore 主要矿物组合为浅色闪锌矿-方铅矿-透辉石(绿帘石、绿泥石) ，其中浅色闪锌矿和透辉石为该类矿石的标型矿物。

The test of sulfur and lead isotope of ores shows that mineralizing matter mainly comes from deep . the ore minerals are typical low - to - moderate - temperature hydrothermal minerals , such as stylotypite , galenite and chalcopyrite 对矿石中硫和铅进行同位素测定，认为硫主要来自深部，显示了地幔硫遭受少量地壳物质混入后的硫同位素组成。

And we compared these deposits for the geological feature and the typmorphic feature of pyrite , galenite , shphalerite which provide mineral basis for prospective value and reserching target of these deposits 而且把几个矿床的地质特征以及黄铁矿、方铅矿、闪锌矿的标型特征进行对比，为矿区的远景评价和找矿靶区的确定提供了矿物学依据。

Germanium enriched mainly in galenite , and cadmium enriched mainly in nonage sphalerite ; isomorphism is the subsistent state of ge and cd , but it ca n ' t exclude the probability that ge and cd absorbed by organic matter Ge主要富集在方铅矿中， cd主要富集于早期闪锌矿中； ge 、 cd的赋存状态为类质同象，但不排除部分被有机质吸附的可能性。

The ore minerals are mainly composed of marmatlte , galenit , pyrrhotite ( pyrite ) , chalcopyrite , or marmatite , galenite , pyrite and hedenbergite . marmatite and hedenbergite are the indicated minerals of the ore 主要矿物组合为铁闪锌矿-方铅矿-磁黄铁矿(黄铁矿) -黄铜矿或铁闪锌矿-方铅矿-黄铁矿-钙铁辉石，其中铁闪锌矿和钙铁辉石为该类矿石标型矿物。

In terms of sulphur isotope result from sphalerite , galenite > pyrite and chalcopyrite , the 8 34s % o value obtained in fozichong orefield ranges mainly between 0 ~ + 5 , which is coincident with the average 5 34s % o value of submarine stratabound sulphide deposits in silurian strate distributed over other areas of the world 地球化学研究显示，佛子冲矿田硫同位素5伦值主要集中分布在0 5之间，与世界其它地区志留系海相硫化物矿床的6吨陆值大体一致。

Kds of 125i ~ on several minerals increased with increase of mineral ratio in mixed materials under atmosphere and low oxygen ambience ; and decreased with decrease of ratio of mixed materials and liquid under atmosphere . under the same condition , kds of 125i " on chalcopyrite and galenite were larger than kds of 125io3 " 大气条件下，随溶液初始ph值的增大， 125i -在黄铜矿、方铅矿上的kd值均呈减小的趋势；而在低氧条件下，随溶液初始ph值的增大， 125i -在方铅矿上的kd值增大。

That offer very valuable referential material for future searching mineral . in recent years , many deposits were confronted with reserves crisis in yuebei region . so we studied the typomorphic feature of pyrites , galenite , sphalerite for deposit of yuebei region , and sum up the genesis of deposit and mineral and reseaching typmorphic feature , these have important value to forecast the deepth of deposit and reaserch the outside of deposit 近几年，粤北地区的许多矿床面临储量危机，因而对粤北地区矿床黄铁矿、方铅矿、闪锌矿的标型特征进行研究，总结出凡口、红岩、大宝山等矿床矿物的成因和找矿标型特征，对于进行矿床的深部预测和外围找矿工作具有十分重要的意义。

For same mineral , desorption of 125i " on it was weaker than 125io3 " , and sorption of 125i i25io3 " on galenite is irreversible . apparent diffusion coefficient da of 125i " in the mixed material were determined by the pass - through diffusion way , da values under atmosphere was given : da = 7 . 29x10 - 12m2 ? s - 1 大气条件下，随体系固液比的减小，固相的量相对在下降， 125i -在矿物材料上的kd值减小；随材料粒度的减小，材料的比表面积增加， 125i -在矿物材料上的kd值有所增加。
