请高手帮忙翻译一段英文

The term ore formation used in formation analysis implies a group of ore deposits of similar mineral composition formed under essentially identical conditions [52]. Ore formations are occasionally subdivided into mineral types,since some deposits included in the same formation have different mineralogical and geochemical properties. The mineral deposits of Afghanistan are classified as magmatic, pegmatitic, carbonatitic, skarn, hydrothermal, metamorphogenic and sedimentary types. These genetic types include various ore formations [30, 37] (Appendices 2-6). The metallogenic zones and ore districts mentioned below are shown in Appendix 1.
Magmatic Mineral Deposits
The magmatic mineral deposits of Afghanistan are genetically associated with ultrabasic rocks (chromite formation) and basic rocks (magnetite-ilmenite formation).
Pegmatitic Deposits
Pegmatites are widely distributed in Afghanistan, occurring mainly in median masses. There are muscovite,rare-metal-muscovite and rare-metal pegmatite formations.
Carbonatite Deposits
During some special investigations performed by G.K. Yeriomenko, B.Ya. Vikhter, and V.M. Chmyriov, avolcanic carbonatite complex was identified in the central part of the late-orogenic Seystan Depression, filled with Neogene-Quaternary sediments [155, 160]. The Khanneshin carbonatite volcano is located in a slightly uplifted fault block. In the west and east, it is bounded by a S-N-trending fault system, whereas in the north,by an E-W trending fault. These deep-seated structures are distinguishable on a magnetic field map.Carbonatite volcanism may be assigned to the Early Quaternary on the basis of finds of Neogene rock xenoliths in the carbonatites, as well as the fact that the latest phonolites are overlain by Middle Quaternary sands.
The investigation showed that some of the rock-types of the Khanneshin volcanic complex contain high concentrations of the elements commonly found in rare-earth carbonatites. These are phosphorus, iron, rareearths,barium, strontium, fluorine, niobium and lead. It was also found that commercial uranium ore was produced by the post-volcanic activity.

用于形成分析的期限矿石形成暗示一个小组在根本上相同情况被形成的相似的矿物构成氧化矿床[52下]。 因为一些放置包括在同一种形成有不同的矿物学和地球化学的物产，矿石形成偶尔地被细分入矿物类型。 阿富汗的矿床被分类作为岩浆， pegmatitic， carbonatitic， skarn，热液， metamorphogenic和沉淀类型。 这些基因类型包括各种各样的矿石形成[30， 37] (附录2-6)。 叙述的金属成矿的区域和矿石区如下在附录1显示。
岩浆矿床
阿富汗的岩浆矿床基因上同超碱的岩石(铬铁矿形成)和基本的岩石(磁铁矿钛铁矿形成)联系在一起。
Pegmatitic储蓄
伟晶岩在阿富汗广泛被分布，发生主要在中间大量。 有白云母、罕见金属白云母和罕见金属伟晶岩形成。
碳酸岩储蓄
在一些特别调查期间由G.K.执行了。 Yeriomenko， B.Ya。 Vikhter和V.M。 Chmyriov， avolcanic碳酸岩复合体在后切向压缩力的Seystan消沉的中央部分被辨认了，充满晚第三纪四个一组的沉积[155， 160]。 Khanneshin碳酸岩火山位于一个轻微地上升断块。 在西部和东部，它由一个S N趋向的缺点系统一定，而在北部，由趋向缺点的E-W。 这些根深蒂固的结构是可区分的在一张磁场地图。碳酸岩火山作用在碳酸岩也许被分配到早四个一组根据晚第三纪的岩石捕虏体发现，并且事实最新的响岩由中间四个一组的沙子躺在上面。
调查表示，某些Khanneshin火山的复合体的岩石类型在稀土元素碳酸岩包含共同地被发现的元素的高浓度。 这些是磷、铁、rareearths、钡、锶、氟素、铌和铅。 它也被发现商业铀矿是由岗位火山的活动生产的。

一词成矿地层分析方法意味着对类似的矿物成分基本相同的条件下矿矿床形成组[52]。矿石编队是偶尔分为矿物类型，因为一些存款在同一地层包括有不同的矿物学和地球化学性质。阿富汗的矿藏被归类为岩浆岩，伟晶岩，碳酸岩，矽卡岩型，热液，metamorphogenic和沉积类型。这些基因类型包括各种矿石形成[30，37]（附件2-6）。该矿区成矿带和下面提到载于附录1。
岩浆矿床
阿富汗岩浆矿床的基因与超基性岩（铬铁矿形成）和（磁铁矿，钛铁矿形成）基性岩。
伟晶岩矿床
伟晶岩广泛分布在阿富汗，主要发生在人民群众中位数。有白云母，稀有金属，白云母和稀有金属伟晶岩地层。
碳酸盐岩沉积
在由竞进行了一些特殊的调查Yeriomenko，B.Ya. Vikhter，并V.M. Chmyriov，avolcanic复杂碳酸盐岩被确定在晚造山Seystan抑郁症与新近纪，第四纪沉积物[155，160]填补的核心部分。碳酸盐岩的Khanneshin火山位于稍微隆起断块。在西部和东部，它四周的南北向断裂系统，而在北方，由东西向断裂。这些深层次的结构是在一个磁场map.Carbonatite火山区别可能被分配到早第四纪晚第三纪的岩石包体的发现，在碳酸的基础上，以及最新的phonolites认为是中东第四纪砂覆事实。
调查表明，该岩石的Khanneshin火山复杂类型包含了一些常用的稀土碳酸发现高浓度的元素。这是磷，铁，rareearths，钡，锶，氟，铌和铅。同时还发现，商业铀矿石由后火山活动所产生
