富集的

The occurrence mechanism of gold is discussed on the basis of microtexture and crystallographyThe fact that the fineness of gold in the deposit is low suggests that the development degree of sulfi...

该矿区金的成色较低的事实，说明了硫化物的发育程度直接影响着金的成色。推断石湖金矿是在多期次成矿的晚期才大量富集的。

The Dabie Mountains are unique among ultrahigh pressure metamorphic terranes in having the most profound post collisional plutonism The Mesozoic shoshonitic and calc alkaline intrusive rocks can be divided into three groups with different isotopic ages, rock assemblages and chemical features Group I consists of late Triassic (~ 210 Ma) mafic monzodiorites It could have been generated by partial melting of enriched subcontinental lithosphere mantle due to slab breakoff Group II consists ma...

第 I组，主要由晚三叠世（约210 Ma）二长闪长岩辉长岩体组成，它可能是在板片断离过程中富集的大陆岩石圈地幔部分熔融的产物；第I I组，由中侏罗世－早白垩世（160～120 Ma）的角闪石英二长岩、黑云母二长花岗岩和正长花岗岩组成，主要是由幔源岩浆的分离结晶与地壳混染共同作用的产物；第II I组，以白垩纪（125～95 Ma）的花岗岩和花岗斑岩为代表，是在热穹窿作用过程中大别杂岩深熔作用和高度演化的产物。

The high quality sand-body trap is characteristic of a large-scale trap, having furthersome types of reservoir facies and favorable reservoir, which are key factors for hydrocarbon enrichment.

优质的砂岩体圈闭具有圈闭规模大、发育有利的储集相类型和良好储集层的特点，这些是油气富集的关键因素。

The possible metasomatic agent was silicate melt in terms of Pb abnormality, which is characterized by enrichment in Pb and depletion in Y and LREE.

依据Pb的异常，可以推断交代物质可能为硅酸盐熔体，且熔体具有较高的Pb和较低的Y含量以及轻稀土富集的特征。

The factors responsible for the gas richness in offshore Bohai are represen ted as follows:The thicker deposition sediments,it made the main source rock-Eoc ene Shahejie Formation reach overmature to generate gas;there is huge thickness of Oligocene source rock-Dongying Formation;there are strong Tertiary tectonic m ovements and high heat-flow in the offshore.

海域天然气比陆上富集的主要因素表现在：沉积厚度大，使得盆地内主要烃源岩始新世沙河街组达到高成熟生气阶段；存在巨厚的渐新世东营组烃源岩；具有较强的晚期构造运动和较高的热流值，在浅层也有天然气聚集的领域。

Characteristics of gold polygenetic compound deposits in the region are demonstrated. The new viewpoint is put forward that the gold deposits in the region belong to "sediment- metamorphism-fluid superposition reconstruction" deposits which are formed by fluid superposition reconstruction in the Diwa stage on the basis of preliminary enrichment in the fore-geosyncline,geosyncline stage.

论证了区内金成矿的&多因复成&特征，提出了区内金矿是在前地槽、地槽阶段金初步富集的基础上叠加了地洼阶段流体成矿作用的&沉积-变质-流体叠加改造矿床&的新观点。

The site that is located on the eminence of nose structure, and far-source the underwater distributary channel and estuary bar experiencing the late dagenetic period B is the most promising for accumulation of oil and gas. Vertically, late diagenetic period B sand layer is advantageous for oil and gas gathering, while late diagenetic subperiod A3 sand layer is disadvantageous for oil and gas gathering.

平面上处于鼻状构造高部位，又处于晚成岩B期的远源水下分流河道、河口坝是最有利于油气富集的部位；纵向上，晚成岩B期的砂体有利于油气聚集，而晚成岩A3亚期的砂体不利于油气聚集。

For the metastable Beta and near Beta phase alloys, with the increasing of hydrogen amounts, the flow peak stresses gradually increase; the elongations for fracture go down through minima and then go up to return or surpass the levels for the uncharging alloys.

由于在高温时氢致弱键机构相对说来不再重要，在正应力高的区域富集的倾向亦大为减小，钛合金在高达上万个PPm的含H量时仍具有相当好的塑性，表现出对氢有巨大的容忍力。

From those mentioned above, it can be concluded that the gold deposits are formed by the reformation and enri chment of ore-bearing bed by Diwa structural activity and magmatism.

据此，可以得出结论，本区金矿的成矿作用是地洼阶段的构造作用和岩浆作用对地槽构造层中的矿源层改造富集的结果。

As the soft belts in older crust, the ductile shear zones in the Archaean greenstone formation are a kind of special linear structure where Au and other metallogenic materials accumulate and migrate.

太古宙绿岩建造中的韧性剪切带构造，是一种特殊类型的线性构造带，亦为古老地壳中的软弱带或薄弱带，易成为金等成矿元素迁移和富集的场所。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
