河北高板河黄铁矿矿物形态及成因

本文初步分析不同形态黄铁矿的形态特征及成因。特别对较典型的叠层石黄铁矿、显微莓球黄铁矿、黄铁矿的微小球粒及较罕见的螺旋状和丝状黄铁矿用生物成因进行了初步解释。认为微生物(藻菌类)对矿床的形成起了很重要的作用,初步提出高板河黄铁矿矿床的形成是生物与沉积共同作用的结果。后期热液活动进一步使成矿物质富集,为较典型的层控黄铁矿矿床。

The Mineral Morphology and Qrgin of the Gaobanhe Pyrite, Hebei

This paper roughly analyses the morphologic feature and origin of the Gaobanhe pyrite. Especially, the typically stromatolitic pyrite, micro-strawberric pyrite, microgranular pyrite and rarely helical and silky pyrite have roughly been explained with the biogenic agency. During the formation process of the deposit, the microbe (homonemeae) is one of the most important elements. The formation of the Gaobanhe pyrite deposit is the result of biogenic agency and sedimentary process. Enrich the mineral-forming elements with post phase hydatothermal action. This deposit is a more typical stratabound deposit
