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 近幾年，粵北地區的許多礦床面臨儲量危機，因而對粵北地區礦床黃鐵礦、方鉛礦、閃鋅礦的標型特征進行研究，總結出凡口、紅巖、大寶山等礦床礦物的成因和找礦標型特征，對于進行礦床的深部預測和外圍找礦工作具有十分重要的意義。

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 地球化學研究顯示，佛子沖礦田硫同位素5倫值主要集中分布在0 5之間，與世界其它地區志留系海相硫化物礦床的6噸陸值大體一致。
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 主要礦物組合為鐵閃鋅礦-方鉛礦-磁黃鐵礦(黃鐵礦) -黃銅礦或鐵閃鋅礦-方鉛礦-黃鐵礦-鈣鐵輝石，其中鐵閃鋅礦和鈣鐵輝石為該類礦石標型礦物。
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主要富集在方鉛礦中， cd主要富集于早期閃鋅礦中； ge 、 cd的賦存狀態為類質同象，但不排除部分被有機質吸附的可能性。
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 而且把幾個礦床的地質特征以及黃鐵礦、方鉛礦、閃鋅礦的標型特征進行對比，為礦區的遠景評價和找礦靶區的確定提供了礦物學依據。
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 對礦石中硫和鉛進行同位素測定，認為硫主要來自深部，顯示了地幔硫遭受少量地殼物質混入后的硫同位素組成。
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 主要礦物組合為淺色閃鋅礦-方鉛礦-透輝石(綠簾石、綠泥石) ，其中淺色閃鋅礦和透輝石為該類礦石的標型礦物。
