摘要
研究发现铅锌矿体普遍分布在含有网状格架藻类和清晰藻团粒藻屑灰岩中,尤其是在含有大量网状格架藻类的藻灰岩中分布着较富铅锌矿体。这个现象在湘西花垣铅锌矿床的李梅、大脑坡、清水塘和排楼等地都已经得到验证。本文将藻灰岩(生物礁相)进一步划分为三个微相:藻坪微相、藻坪浅滩微相和藻坪浅滩改造微相,并对其含矿性进行了讨论。
There is found that lead-zinc ore bodies are universally distributed in algal limestone containing reticulated algae and clear algae pellets,especially in algal limestone containing a large number of reticulated algae,there are relatively richer lead-zinc ore bodies distributed.This phenomenon has been verified in the Limei,Danaopo,Qingshuitang and Pailou of Huayuan lead-zinc mineral deposit in west Hunan.This paper shows that the algal limestone (biohermal facies) is further divided into three microfacies:algal flat microfacies,algal flat shoal microfacies and algae flat shoal transforming microfacies,and its ore-bearing properties are discussed.
