The optical properties of barium titanate crystal were determined by using super thinsmooth thin sections of 18μm thick, and 618 epoxy resin with index of refraction of 1.5699was used as adhesive. Barium titanate is transparent and colourless, usually euhedral or semi-euhedral with po-sitive high relief; and two directions of cleavage, {100} being perfect and {001} medium,strongly birefringence, the maximum interference color can be as high as third-order me-dium; parallel extinction; sign of elongation either positive or negative; biaxial positive,2V=42°, v>r;optical orientation: N_g||a, N_m||c, N_p||b. The barium titanate porcelain has prismatic magniphyric or grainulitic microstructures.

The formation process of sedimentary deposits might be divided into three minerogenic stages,i.e.,syngenetic sedimentation,diagenesis and anadiagenesis (katagenesis).The features of sedimentary ore deposits so far preserved must have been formed chiefly at the last minerogenic stage. Based on formation process and intensity of various minerogenic stages,the author has divided the sedimentary deposits into four genetic subtypes: 1.Sedimentary syngenetic deposit; 2.Sedimentary diagenetic deposit; 3.Sedimentary...

The formation process of sedimentary deposits might be divided into three minerogenic stages,i.e.,syngenetic sedimentation,diagenesis and anadiagenesis (katagenesis).The features of sedimentary ore deposits so far preserved must have been formed chiefly at the last minerogenic stage. Based on formation process and intensity of various minerogenic stages,the author has divided the sedimentary deposits into four genetic subtypes: 1.Sedimentary syngenetic deposit; 2.Sedimentary diagenetic deposit; 3.Sedimentary diagenetic-anadiagenetic deposit; 4.Sedimentary anadiagenetic deposit. The siderites present in normal sedimentary deposits and sedimentary rocks were formed either at diagenetic stage or at anadiagenetic stage,with the former called diagenetic siderite,and the latter anadiagenetic siderite.Their chief chara- cteristics are given in Table 1. The gray,even,impalpable and fine-grained siderites seem likely to be pro- ducts of diagenesis,as evidenced by following facts: (1)They are closely associated with such organic substances as coal seam, carbonaceous shale,black shale and asphaltite(Fig.6,7,Table 5).when the organic carbon content is higher than 0.3%,siderite+chamosite+pyrite facies will be formed(Figs.6,7);if it is less than 0.3%,hematite facies occurs(Figs.8,9, Table 5),containing a small amount of siderite. (2)Hematite has been commonly replaced by siderite to form lots of re- placement fabrics,especially pseudomorphic fabrics and replacement remnants (Fig.10). (3)Siderites are in close association with such diagenetic minerals as cha- mosite,thuringite,framboidal and pyrite. The rice-yellow,coarse and large grained siderites are products of anadia- genesis,as can be substantiated by following evidence: (1)They have coarse or large grains,abundant fluid inclusions,relatively pure composition and very weak alteration. (2)Veined,drusy,comby structures and precipitation textures are fre- quently seen. (3)The veined orebodies composed of siderites are seen to cut across strata or occur along the exfoliations of strata. (4)Siderites are intimately related to anadiagenetic magnetite,specularite, maghemite,quartz and rock crystal,calcite,pyrite,galena and sphalerite. The replacements,whether they occurred at diagenetic stage or at anadia- genetic stage,are very distinct and of great significance.

沉积矿床的形成过程,可明确地划分为同生作用、成岩作用与后生作用等三个矿化阶段。现在所见到的沉积矿床,主要是最后矿化阶段改造的结果。根据沉积矿床所经历矿化阶段的不同和表现强度的不同,作者将沉积矿床划分为四种成因亚类:(1)沉积同生矿床;(2)沉积成岩矿床;(3)沉积成岩-后生矿床;(4)沉积后生矿床。产于沉积岩和沉积矿床中的青灰色微细均粒菱铁矿系成岩作用形成,米黄色或淡黄色的粗至巨粒的成分较纯的菱铁矿系后生作用形成。它们都不是同生作用形成的。

This paper describes an experimental investigation on the direct filtering of Wuhan's East Lake water containing algae in a radial flow filter with uniform- sized media.The experimental result shows that,under the circumstances of inflow turbidity<30 degrees,algae content<40million/L and filtering velocity<8m/h,the effluent turbidity is below 2 degrees,and the filtering period is more than 14h,which is a good outcome compared with that of upward flow double layer filters.
