The former is the major pre-condition of the formation of gold mineralization concentrated district,the latter is a main a- gent for the gold remobilization from source bed,...

区内金矿床可划分为绿岩建造、花岗岩建造、火山岩建造和沉积岩建造金矿床四大类。探索新类型和加强老矿区的深部找矿是今后主攻方向。

Under the good drainage condition, when degree of mineralization in the return water was less than soil salineness, irrigation with the return water can make soil desalinited evidently.

通过利用低矿化度回归水的土柱模拟实验研究表明，在排水较好条件下，含盐1.3—1.6g／L的低矿化度回归水灌溉可使中轻度盐渍化土壤脱盐。

The close time_space relationship between shoshonite in the northern part of Siziwang Banner and fluorite mineralization implies that the fluorite deposit might have resulted from the lithospheric thinning of eastern China and the replacement of the lower crust.

萤石成矿作用与钾玄岩的时空关系暗示了萤石的成矿过程可能是中国东部岩石圈减薄和下地壳的置换地质事件的结果。

The main reason of the lower soil net nitrogen mineralization rate in Eucalyptus forest could he the decrease of available substrates and the uptake of larger amount of soil nutrients by the fast growth of Eucalyptus. The soil nutrients in shrubland had a quick restoration rate after burning.

火烧桉林氮矿化速率较低的主要原因是其可利用基质的减少和桉树快速生长吸收大量养分所致，火烧灌草坡土壤养分的恢复速度较快。

In Eucalyptus forestland, soil organic carbon, total nitrogen, available potassium contents and soil PH decreased significantly; soil available phosphorus and exchangeable magnesium contents, net nitrogen mineralization rate and ammonification rate also decreased but showed no significant difference. In shrubland, soil exchangeable calcium content increased significantly, but the contents of other nutrients had no significant change.

结果表明：火烧3年后，桉林土壤有机碳、全氮、速效钾和pH含量明显降低，土壤有效磷、交换性镁、土壤净氮矿化速率和氨化速率降低，但不显著；火烧灌草坡除土壤交换性钙明显增加外，其他土壤养分均无显著变化。

This class of deposits is characterized by the abundance of iron oxide in the ores and the associated intensive regional sodic alteration. They may occur in Proterozoic intracraton or Phanerozoic continental margin volcanic arcs with nearby intrusive complex or evaporite. The spatially and temporally associated intrusive rocks are magnetite-series granitoids. Mineralization mainly occurs in second order echelon structures near the main regional structure.

该类矿床以矿石中含有大量的铁氧化物且伴有很强的区域性钠质蚀变为特征，可以产于元古代克拉通内或新生代大陆边缘岛弧环境，其周围具火成岩或含蒸发盐层，时空上与之有关的侵入岩为磁铁矿系列花岗岩，矿化主要产于近区域主断裂的羽状次级断裂中。

Under the condition of laboratory incubation,the C loss of organicmaterials during their mineralization was greater than their N loss,inducing ahigher residual amount of organic organic N.During the decay of maize andrice staw with a wide ratio of C/N.soil microbes could fix N,but the fixationrate was quite low,only 0.2-0.9g N/assimulated 100g organic C.

在实验室培养条件下有机物料在矿化分解过程中C的损失总是大于N的损失，因此有机N的残留率明显高于有机C的残留；且由于灰分总量不变，有机物料的残留率也略高于有机C的残留率；〓比较宽的玉米秸和稻秸在腐解过程中发生了自生固N作用，但其固N效率仅为C：N=100：0.2-0.9，即每同化100g有机C，只能固定

Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.

矿体产于红岩寺—黑山复式向斜南翼金井河—胡家沟次级背斜南翼近轴部断裂中，赋矿岩石为泥盆系青石垭组中上部白云质岩，其空间展布明显受背斜陡倾南翼近轴部的层间断裂-裂隙带构造控制，矿石主要有团块状和网脉状，其后生成矿现象非常明显。

Gold mineralization majorly developed in fractured fault belts of Neoproterozoic Roncheng superunit.

金矿化主要发育于新元古代荣成超单元的断裂破碎带中。

Multi-metal mineralization, such as silver, cooper and molybdenum majorly developed in contacted zone of fractured fault belt in Weideshan superunit and Paleo-proterozoic Jingshan group.

银铜钼等多金属矿化主要发育于伟德山超单元的断裂破碎带或与古元古代荆山群的接触带中。
