形成边缘

The sedimentation is the foundation, affecting the basic pattern of the reservoir,and the sedimentary facies zones beneficial to the formation and evolution of the reservoir includes platform edge bank facies, introplatform point beach facies and acclivity sedimentary facies, etc.; the diagenesis is the key factor, determining the pattern and scope of the final distribution of the reservoir and being of great influence on reservoir structure, and the diagenesis of promoting the formation of storage rooms is mainly the dissolution occurred during hypergene stage and burial stage;and the tectonism is the condition of influencing the connectivity among various reservoir bodies and among the storage rooms within a single reservoir body.

该套储层是在4亿年左右的地质历史中，由沉积、成岩和构造作用相互影响而形成的最终成果：其中沉积作用是基础，影响着储层的基本形态，有利于储层形成与演化的沉积相为台地边缘滩、台内点滩和上斜坡等沉积相带；成岩作用是关键，决定了储层的最终分布形态和范围，对储层结构的影响至关重要，促进储集空间形成的成岩作用主要有表生期和埋藏期的溶解作用；构造作用是条件，影响着各储集体之间以及单一储集体内部储集空间的连通情况。

These results show that there are reciprocal CGRP-positive fiber connections among the MrD of the striatum, amygdaloid nucleus, bed nucleus of the stria terminals and substantia nigra and its dorsolateral area. It is suggested that there is an affinity relationship between the MrD and limbic system.

Opinions vary on the genesis of this type of gold deposits. On the basis of observation and study in this area, with information up to date from other researchers, the authors bring forward that the formation of Muruntau-type of gold deposits in South Tianshan area is closely related to giant nappe structures, especially to the ductile shear zone.

关於该类金矿床的成因也是众说纷纭，根据作者近几年在南天山地区的调研得到的一些认识，以及其他学者对该地区穆龙套型金矿床的最新研究成果，认为南天山地区穆龙套型金矿床的形成与南天山褶皱造山带形成过程中板块边缘的大型逆冲推覆构造，特别是与其伴随的韧性剪切变质变形带具有密切的关系，而与这些构造作用伴随的花岗质岩浆的侵入作用是形成该类金矿床的必要条件。

1Arid-subarid palaeoclimate was helpful for mechanical weathering of source rocks and torrent forming;(2) The combination of source rocks and their occurrence were liable to cause mechanical breakdown of rocks and form mudflow,(3)There was a considerable height difference along the border of the basin,(4) The density of subaqueous mudflow was 2.4-2.7g/cm3;(5)There was a high rate of accumulat...

认为本区沙三段时期满足重力流的形成条件，主要表现在六个方面：(1)干旱-半干旱的气候环境有利于母岩的机械风化和山洪的形成；(2)母岩的组合及其产状容易发生机械破碎，形成泥石流；(3)盆地边缘地形高差悬殊；(4)高密度的水下泥石流；(5)堆积速率大；(6)水深位于半深湖以下。

At 4 weeks following implantation, cells on the surface of coralline hydroxyapatite were found and connective tissues were seen in the material pores in the experimental group. Cells on the coralline hydroxyapatite were observed only in the control group. At 8 weeks, new bone formation was detected on the surface of coralline hydroxyapatite; bony tissue deposition and a few chondroid tissues were found in the pores or surrounding the pores in the experimental group. A few fibrous connective tissues were observed in the control group. At 12 weeks, abundant mature woven bone was detected on the surface of coralline hydroxyapatite; medullary cavity-like structure and vessels were found in some regions in the experimental group. No new bone or bony tissues were found in the control group.

植入材料后4周，实验组可见珊瑚羟基磷灰石表面有细胞生长，孔隙内有结缔组织长入；对照组仅见珊瑚羟基磷灰石表面有细胞生长。8周时珊瑚羟基磷灰石表面有新生骨形成，孔隙内和孔隙边缘可见骨样组织沉积和少量软骨样组织形成；对照组仅见少量纤维结缔组织长入。12周时珊瑚羟基磷灰石材料表面有较多成熟编织骨形成，部分区域可见髓腔样结构形成，并有血管长入；对照组仍未见新骨及骨样组织形成。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

That if the process can produce much liquid phase during the sintering, and which can become into completely-crystal needle-shap or aborization or bar-shap calcium ferrite instead of glass in the cooling process; if the magnetite is interweaved by the caking into the melting corrosion structure, the granular structure or the eutectic structure instead of exiling in the massive isolation; if the mount of the poreis is little, and uniformitly distributing; if the grain is little; if the organizational structure is symmetrical, all of which can improve the quality of the sintering.

另外还归纳出有利于强度提高的工艺参数和操作制度。分析工业试验和水钢现行生产的矿物组成、结构表明，水钢烧结矿以他形晶磁铁矿为主，铁酸钙为主要的粘结相，多形成熔蚀结构、粒状结构和共晶结构，强度较高；而在台车边缘和表层，由于存在较严重边缘效应和点火温度较低，使该区域的烧结矿组织结构疏松，局部呈蜂窝状或薄壁大孔状，铁酸钙较少而硅酸二钙和玻璃质较多，形成骸晶状结构和磁铁矿连晶，强度较低，致使返矿升高。

The Cenozoic of the deep-water basin in the north of the South China Sea is the passive continent margin which has the continent marginal characteristic of being tensionally rifted. It is favorable for the formation of deep\|water reservoirs and gas hydrate.

南海北部深水盆地新生代处于准被动大陆边缘的区域地质背景，具有北部拉张裂陷的大陆边缘性质，其凹陷裂陷深、沉积充填规模巨大，不仅有利于深水油气藏的形成，而且亦是天然气水合物形成与分布的有利区域。

Based on the detailed study of seismic tomography image in South China, and according to the geotectonic environment and shape and heat of asthenosphere upwelling, we divided the structure of lithosphereasthenosphere at the Mesozoic upper mantle of Eastern China into three types.(1)Continental platform area (North China platform and Yangtze platform): asthenosphere upwelled along paleorift; over the plume head, the granitic rocks of crust and mantle mixed and correspondingly, Au, Cu, Mo, PbZn, etc. mineralizationconcentrated regions were formed; and at the steep contact belt of asthenosphere and the thick area of lithosphere, mediatebasic complex was formed.(2)Central area of fold zone: asthenosphere was "recumbent" at suitable depth, with adequate heat and in a great extent; by heat conduction, the interior of partial crust remelted, and the crustsource granitic rocks, and correspondingly, W, Sn and rare elements mineralizationconcentrated regions were formed.

在深入研究华南地震层析成像的基础上，按照大地构造环境和软流圈上涌形状和热度，将中国东部中生代上地幔中岩石圈软流圈构造划分为3类：(1)陆台区，软流圈沿古裂陷上涌，其柱头上方形成幔壳混熔花岗质岩及相应Au、Cu、Mo、PbZn等矿集区，并于软流圈与岩石圈厚区之陡接触带形成中基性杂岩及相应Fe矿集区；(2)褶皱带中心区，软流圈在适当深度、热量充足、较大范围内&平卧&，因热传导而致使地壳内物质部分重熔，形成壳源型花岗质岩及相应的W、Sn、稀有元素矿集区；(3)褶皱带边缘区(大兴安岭南部及华南南缘)，在软流圈上涌柱上方形成幔源或幔壳混熔的花岗质岩，相应为Cu、Au、PbZn、Mo、Ag矿集区。

The marginal division was a flat fan-shaped structure with a volume of (0.48±0.02) mm3, a maximum rostral-caudate axis of 1.6 mm, a maximum dorsal-ventral axis of 2.158 mm, and a widest axis (the diameter at lateral-medial coronal brain section) of 0.17 mm. The marginal division also moved progressively externally from the rostral section to the caudate section, but its scope was larger than that of others. The whole marginal division changed evenly from the rostral section to the caudate one. Its flat structure widened progressively and its dorsal-ventral diameter narrowed gradually and became plate-shaped.

边缘区呈现一个片状扇形结构，体积为(0.48±0.02) mm3，最大嘴尾径为1.6 mm，最大背腹径为2.158 mm，最大内外径为0.17 mm；同尾壳核和苍白球一样从嘴侧到尾侧随着脑平面的增宽边缘区亦逐渐向外侧移位，其移位的幅度亦明显大于脑平面增宽的幅度；整个边缘区从嘴侧到尾侧呈均匀变化，其片状逐渐变宽，长度逐渐变小，从而形成一个盘状结构。
