The history of using SEM to study surface texture of minerals is rather short,especially scarce cases are the observation of quartz in rocks of comparatively older geological ages.Therefore, surface texture of quartz grains were studied under SEM in this paper.Samples were collected from quartz-magnetite ores of the main ore-body in Mekeng Iron Deposits, Clear traces, caused by subaqueous mechanical collision, were found to be retained on these quartz grains, even though they had passed through diagenesis and...

The history of using SEM to study surface texture of minerals is rather short,especially scarce cases are the observation of quartz in rocks of comparatively older geological ages.Therefore, surface texture of quartz grains were studied under SEM in this paper.Samples were collected from quartz-magnetite ores of the main ore-body in Mekeng Iron Deposits, Clear traces, caused by subaqueous mechanical collision, were found to be retained on these quartz grains, even though they had passed through diagenesis and alteration of later periods.Thus, It is clear that these quartz came mainly from terrigeneous fragments, and formed after passing through aubaqueous transportation and sedimentation in epeiric environments.Accordingly, it may be deduced that the primitive iron elements of these iron ores which paragenesis with quartz were produced from terrestrial source. The genesis of Mekeing Iron Deposits have two main different points.l)The contact replacement deposits; 2) The sedimentation-later hydrothermal superimposed alteration deposits. It is supposed that this paper may be used as an evidence to prove the sedimentary genesis of this Deposits.

运用扫描电子显微镜来研究矿物表面结构,仅有很短的历史,特别是对时代较老的地层中石英的观察,尚属寥寥.为此.我们对福建马坑铁矿主矿体的石英-磁铁矿矿石中的石英作了这方面的尝试.观察发现,尽管这些石英历经成岩作用和后期改造,但它们的颗粒表面仍保留有明显的水下机械作用的痕迹.从而说明这些石英主要来自陆源碎屑,经过水下搬运,在浅海环境沉积而成.因而有理由可以推测,与石英共生的铁矿,其原始物质也可能来自陆源. 关于马坑铁矿的成因,主要有二种不同的观点.1)、接触交代矿条;2)沉积一热液迭加改造矿床.本文可作另沉积成因的一个佐证. 福建马坑铁矿是一个大型隐伏矿床.主矿体位于下石炭统林地组之上,相当于中石炭统经畲组的层位中.矿体呈厚大似层状产出.矿体产状与围岩产状基本一致.主要金属矿物为磁铁矿,脉石矿物以透辉石、石榴石、石英为主.矿石结构以他形粒状镶嵌变晶结构为主,矿石构造以块状、浸染状、斑杂状为主,常见有条带状构造和皱纹状构造.矿石类型以石英-磁铁矿、透辉石-磁铁矿为主,并有石榴石-磁铁矿矿石. 本文是通过扫描电子显微镜的观察,对石英-磁铁矿矿石中的石英表面结构特征进行初步研究.

The hypotheses concerning the origins of Yutang lead-zinc ore deposits include such opinions as the sedimentary, the low temperature hydrothermal, the lateral secretion, the sedimentary-transformation. Whether the origin of the deposit is mainly of sedimentary or transformation is still in controversy. By the application of the methods of mathematical analysis and deduction, this paper holds that the lead and zinc of the deposits mainly originate from the adsorption of ions of lead and zinc by the algae, thereby...

The author has studied the trace elements in sphalerite and pyrite from 27 Pb-Zn-pyrite ore deposits of Southern Hunan, and concludes that the value of Ga/In<1 and Co/Ni>1 in sphalerite and pyrite respectively have demonstrated the ore deposits heing hydrothermal type formed during the stage of post-magma acti-vity; and to the contrary, the ore deposits are classified as the sedimentation-trans-formation type. And according to the nature of the elements itself, the author has inquired into the physical-chemical conditions for the formation of the two types of ore deposits as revealed by the correlation value of trace elements men-tioned above; and holds that, in comparison with the hydrothermal ore deposits of the stage of post-magma activity, the sedimentation-transformation type of ore deposits are formed under the conditions characterized by the addition of oxygen that leads the increment, in some degree, of fO_2。

作者研究了湘南27个铅锌黄铁矿床(点)的闪锌矿和黄铁矿的微量元素,得出闪锌矿的Ga/In<1,黄铁矿的Co/Ni>1是岩浆期后热液矿床;反之则是沉积改造矿床。又根据元素本身的性质,对上述微量元素比值差异所反映的两类矿床形成的物理化学条件进行了探讨,认为与岩浆期后热液矿床相较,沉积改造矿床是在有外来氧的加入,致使fO_2有所增高的条件下形成的。
