The pyritic lead-zinc deposits of Chishiachan in the Nanjing Hills, some 20 KM. east of Nanjing of the Kiangzu province, discovered in 1950, have long been thought to be undoubtedly epigenetic and hydrothermal in origin.

The pyritic lead-zinc deposits of Chishiachan in the Nanjing Hills, some 20 KM. east of Nanjing of the Kiangzu province, discovered in 1950, have long been thought to be undoubtedly epigenetic and hydrothermal in origin. The writers recently studied the deposits in detail. They are much interested when they find out different sorts of framboidal pyrite in the concretionary and also in the laminated ores of the deposits. Some of the framboidal pyrite have distinct cellur structures of fossilized tissues of algae, and some can be identified to be Solenapora. The framboids are now made up mainly of pyrite and melnikovite. The interstices between the "cells" are mostly filled with organic matter. The internal structures of the cellular tissues are of two kinds: (1) the cells, about 20μ in size, are arranged in radiating siphon-like bodies, and (2) the cells, of 40 to 60μ in sizes, are orderly arranged. Associated with the iron sulphide framboids, there are also some metacolloidal structures composed of marcasite and wurtzite. It is probable that, the sulphides were formed when the decaying biogenic protoplasm occurred in the presence of sulphur-reducing bacteria to produce HS~-, which combined with Fe~(++) to yield framboidal melnikovite and its recrystallized product, pyrite. Therefore, they were formed by biochemical processes, as a result of syngenetie sedimentation and early-diagenetic products. The ore bodies are mostly stratiform, stratoid, or in large lenticular forms. The ores are laminated, banded, or in concretionary layers. These structures of the ore bodies are in the main parallel to the stratification of the country rocks. Such kind of ore will constitute the main industrial ores of this district. The age of the ore formation belongs to the early to middle Carboniferous period. But, there are also evidently hydrothermal effects which are superimposed upon the syngenetic ore-forming processes, resulting in the formation.

我们详细地研究了南京栖霞山铅锌硫矿床。特别有意义的是在结核状、层纹状矿石内发现了各种各样的草莓状黄铁矿。经研究藻类的专家鉴定,其中有些具藻类化石的细胞组织,有些具管孔藻类化石的细胞组织。它们主要是由黄铁矿和胶黄铁矿组成。其细胞的间隙常为有机质所充填。但其内部结构特征是:(1)由粒径约20μ的细胞排列成管状放射体;(2)主要由粒径自40—60μ的细胞有序地排列。其生成可能是当生物原生质腐烂时,遂发生硫还原细菌产生HS~-。这种HS`-与Fe~(2+)相结合生成草莓状黄铁矿。因此,它们是生物化学作用的产物,是同生沉积——早期成岩阶段的结果。与之伴生的还有变胶状构造。这类矿石将成为本区主要的工业矿体。其生成时代属早——中石炭世。矿体呈层状、似层状是或大透镜体。其产状与围岩基本上是一致的,但局部有斜交(热液迭加的结果)。但本区也有明显属后生的脉状、网脉状、浸染状及晶簇状矿石。它们往往具有显著的充填交代特征。此中普遍地表现为闪锌矿交代黄铁矿,方铅矿交代闪锌矿。其产出常与断裂构造及硅化、重晶石化具有密切的关系。显然,这是多期多阶段热液迭加的成矿现象。本区的铅锌矿,主要与这种成矿作用有关。因此,本区的矿石是由同...

The results of thermodynamic calculations demonstrate that the pH and Eh values for bottom sea water enriched in organic matter decrease greatly owing to bacterial reduction of sulfates in the sea water. Syngenetic sulfide ore beds associated with the Jiashengpan strata-bound Pb-Zn-S ore deposit are believed to be precipitated under conditions of pH varying from 7.08 to 7.17 and Eh from -0.232 to -0.418V.

The results of thermodynamic calculations demonstrate that the pH and Eh values for bottom sea water enriched in organic matter decrease greatly owing to bacterial reduction of sulfates in the sea water. Syngenetic sulfide ore beds associated with the Jiashengpan strata-bound Pb-Zn-S ore deposit are believed to be precipitated under conditions of pH varying from 7.08 to 7.17 and Eh from -0.232 to -0.418V. It is established that in the reducing system in the sea water where reduction of sulfates by anaerobic bacteria took place, paleosalinity is an important factor affecting pH and Eh changes and controlling the formation of sulfide ore deposits. The present study shows that the quantitative evaluation of physico-chemical condi-tions can be effected from thermodynamic calculations on the basis of geochemical data.

本文以甲生盘层控铅-锌-硫铁矿床为例,应用化学平衡及热力学计算方法定量估计同生硫化物层形成的古盐度、pH和Eh条件。计算表明,在富有机质的还原性海盆地中,细菌还原硫酸盐反应使体系pH、Eh值明显降低。甲生盘矿含矿层沉积环境为:S≈70‰,pH=7.08~7.17,Eh=—0.230~—0.418V。高盐度、强还原及偏低的pH环境有利于硫化物富集。
