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,本区的矿石是由同生沉积——热...

Through detailed field and laboratroy studies, it is found that in the Fenglin mining district and its vicinities, Dongxiang, Jiangxi, volcanics occur in the Zishan formation of lower Carboniferous age and in the lower part of the Huanglung limestion formation of Middle Carboniferous age. They comprise dacite, rhyolite lavas, and acid to acid-intermediate tuff, tuff-breccia, and tufaceous sediments, with a total thickness of more than 20 meters. Interbedded with these chiefly submarine volcanic beds and other marine sediments, are stratiform pyritic copper beds, consisting chiefly of pyrite, melnikovite, siderite, chalcopyrite, and some sphalerite and galena, which attain a total thickness of some 28 meters, and constitute a mediumsized copper mining district. Above the pyritic copper beds, occur siliceous hematite beds of some 13 meters in thickness, succeeded by chert beds and ferruginous flint of 20—30 meters in thickness, The entire succession in by Huanglung limestone. Most of siliceous hematite beds are tungsten-bearing and those considered to be low-grade tungsten ores measuring some 8 meters in thickness. Tungsten occurs mainly as absorbed ions the ferric oxide layers, averaging about 0.3—0.4% WO_3. Only through later recrystallization accompanied with some intrusive apophyses of granodiorite porphyry, does it occur in minute crystals of ferberite and scheelite. Due to their close association with submarine volcanics and marine sediments, these pyritic copper deposits and the tungsten-bearing hematite beds are considered to be formed by submarine exhalant-sedimentary processes. During the yanshanian period there have been some weak reconstitution and superimposition by hydrothermal processes.

通过野外和室内的仔细研究,在枫林矿区及其外围下石炭统梓山组及中上石炭统壶天群下部,发现有广泛的火山岩,包括英安斑岩、流纹岩,及酸性到中性的凝灰岩,凝灰角砾岩及火山碎屑沉积岩等,总厚度20余米。与这些主要海底火山岩层及其他海相沉积物互层的为层状黄铁矿型铜矿层,它主要是由黄铁矿,胶黄铁矿,菱铁矿,黄铜矿,辉铜矿及少量闪锌矿等组成,其总厚度约28米,构成中型的铜矿山。在黄铁矿型铜矿层之上,有厚达13米的硅质赤铁矿层及20—30米厚的硅质岩层,再往上完全复盖以壶天群灰岩。大部分硅质赤铁矿层都是含钨的,并构成低品位的钨矿床,其厚度为8米,钨主要呈离子状态被吸附在赤铁矿层中,只有在受到花岗斑岩影响的地段,经过后期热液作用,才偶尔见到钨铁矿、钨锰矿及白钨矿的细小晶体。总之,由于这些黄铁矿型铜矿床及含钨赤铁矿层与海底火山岩及海相沉积物具有的密切联系,所以它们被认为是由海底火山沉积作用形成的。并在燕山期又受到微弱的热液迭加及改造作用。
