According to model, lead zinc ore bodies of mineral deposit, celestite ore bodies and gypsum ore bodies are distributed by the incomplete dome shape. The sandstone type ore bodies like a curved surface shape, is on the top, wide distribution, which like the top cover of a mushroom. The limestone breccia type ore bodies, under the sandstone type ore bodies, with mostly irregular vein shape, lens body shape, locate at the root of the mushroom. Gypsum and celestite ore bodies, accompanying with limestone breccia type ore bodies with the shape of vein, lens body, distribute under the sandstone type ore bodies.

根据模型显示，金顶矿床铅锌矿体、天青石矿体和石膏矿体呈不完整的穹隆状分布，砂岩型矿体在上，为曲面状，分布广，似一蘑菇的顶盖，而灰岩角砾岩型矿体分布局限，部分产于砂岩型矿体之下，多为不规则的脉状、透镜体状，构成蘑菇的根部；石膏和天青石矿体主要与灰岩角砾型矿体相伴产出，呈脉状、透镜体状，多分布于砂岩型矿体下部。

The ore is characterized by veinlet structure, net-veined structure and comb structure, and the gradual outward transformation of ore structure from veined via net-veined and veinlet-disseminated to disseminated is common. These characteristics in ore fabrics and the occurrence of cryptoexplosive breccia are strong evidences that Songxi Ag-Sb deposit is a hydrothermal deposit.

矿体中发育大量的脉状、细脉状、网脉状和梳状等充填交代构造，由矿体向围岩常可见脉状→网脉状→细脉浸染状→蚀变围岩的渐变过渡现象，这些构造特征以及热液破碎角砾岩的出现，为嵩溪银锑矿床的浅成热液成因提供了有力证据。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

The Shengmikeng vein-type lead-zinc deposit is located in Huanggangshan volcano-tectonic depression of the Mesozoic volcanic belt in Northern Wuyi.The ore featured by veinlets and disseminations is hosted both inside the fault zone in the upper Jurassic Ehuling ignimbrite and the potassic trachyte porphyry.

摘 要：生米坑铅锌矿床位于北武夷中生代火山岩带的黄岗山火山盆地内，已知铅锌矿体呈脉状产于侏罗系上统鹅湖岭组流纹质熔结凝灰岩的断裂内，或呈细脉——浸染状分布于钾质粗面斑岩内，发育钾长石化、绿泥石化、硅化等蚀变。

Some spore-pollen assemblages of late Trias and the youngest zircon of 225Ma were also obtained in this type.Deriveration of the ore is from the upper crust according to the features of trace elements,zircorn U-Pb age and initial value of ~(87)Sr/~(86)Sr.It has not any charateristics of the mantle.

底辟-侵位角砾岩是本次工作新发现的，它在空间上与构造-膏溶角砾岩密切伴生，剖面上呈脉状或火焰状分布，局部呈脉状穿刺于围岩中，其胶结物中含有晚三叠世的孢粉组合，最年青锆石的年龄为225Ma，角砾岩本身是铅和锌的富矿体。

Based on the a series of research carried in typical gold lodes in Linglong, Jiapigou, Dongfeng and Xiaoqinling and related data, it is suggested that the deposit type is concentrated in the circumference of the North China Platform, occurring in the Archean granite-greenstone belts, being adjacent to deep-cut faults and being accompanied by the Mesozoic, remelted l-type granites. The spatial distribution features of the deposit type indicate that the deposits are closely related to the multiple evolution of the mantle plumes.

通过对玲珑、夹皮沟、东风和小秦岭等典型中深脉状金矿及相关资料的研究表明：中深脉状金矿主要分布于华北地台的周边，位于太古代花岗—绿岩带中，与深大断裂相邻，同中生代重熔I型花岗岩伴生，这种空间展布特征与地幔的多级演化有关。

The shapes of ore bodies are like veins and haricots.

矿体呈脉状、复脉状、扁豆状等形态。

This paper mainly deals with some spatial regularities,or called distribution law s of gold lodes and ore bodies,which are significant and efficient in site prediction for these deposits,including distribution law s of the so called major-structure constraints;of t.

文中主要总结了对脉状金矿定位预测极为重要且效果明显的若干脉状金矿床及金矿体在空间上的分布规律、控制因素和形成机制，包括主构造控矿律、群簇产出律、对应产出律、等距分布律、分段富集律、侧伏律和成矿界面律等。

In the space, along with increased distance from the main ore-controlling structures, the frequency of P type of pyrite and their thermoelectricity also decreased gradually. Within one lode, from the upper to the lower parts of an ore body, the vertical change of pyrite in thermoelectricity as the follows:① when the ore body is stable, that is when the ore body is uniformly and continuously mineralized, the Dp andαvalues keep increased from shallow to deeper parts;② when an ore body is discontinuously mineralized, the Dp andαvalues have a wavy increasing tendency from the shallow to the deeper;③ when the deeper part of an ore body contains abundant, Co and Ni high mafic dykes, the Dp andαvalues of pyrite decreased from the shallow to the deeper parts of an ore body, that is, an reversed zoning of pyrite thermoelectricity occurs for pyrite in this situation contain more Ni and Co and belongs to N type.④ For the deposits hosted in the Archean metamorphic rocks, because all of the pyrite in this case is N-type, the vertical change of pyrite is not featured by the transition of pyrite type, but by the increased values of Vnp and α from the shallow to deeper parts of an ore body.

在空间域上，水平分带规律为：随远离主干断裂，矿脉中P型的出现频率逐渐降低或热电系数值逐渐变小；在同一条矿脉中，这是由于矿化不均匀性及脉岩的影响，由矿体的上部到下部，它的垂向变化特征可以有如下几种变化形式：①由矿体的浅部到深部，黄铁矿的Dp值、或α值呈稳定升高的趋势时，矿体往往表现为矿化均匀，连续性好、延伸稳定；②由浅部到深部，黄铁矿的Dp值、α值呈波状变化，但总体又具有增大的趋势时，所在的矿体连续性差；③当矿脉的下部发育有大量的基性脉岩时，由于基性脉岩中常含有较高的Co、Ni，使其中黄铁矿的Co、Ni含量较高而呈N型导电，由矿体的上部到下部，黄铁矿的Dp值、α值呈减少的趋势，而造成黄铁矿热电性特征的逆向分带，④产于太古代变质岩中的中深脉状金矿，由于其中的黄铁矿均为N型导电，所以垂向变化规律并不表现为导型的改变，只是Vnp值或α值从矿体的上部到下部由小变大。
