参考译文：
金属在地壳中和海底的存在形式取决于它与 其环境元素，尤其是与氧、硫和二氧化碳 的化学反应活性。金和铂主要以“自然” 或者说金属形式存在。银、铜和汞通常以 硫化物、碳酸盐和氯化物形式存在，其单 质形式亦存在。活性更大的金属总是以化 合物形式存在，例如，铁以氧化物和硫化 物形式存在，铝和铍以氧化物和硅酸盐形 式存在。自然产生的化合物就称为矿物， 大部分矿物是根据它们的化学成分而命名 [如方铅矿---硫化铅；闪锌矿---硫化锌； 锡石---锡的氧化物]。

Introduction 导论
1.1 Mineral and Ores 矿物与矿石
1.1.1 Minerals 矿物
The forms in which metals are found in the crust of the earth and as seabed deposits depend on their reactivity with their environment, particularly with oxygen, sulphur, and carbon dioxide. Gold and the platinum metals are found principally in the native or metallic form. Silver, copper, and mercury are found native, as well as in the form of sulphides, carbonates, and chlorides. The more reactive metals are always in compound form, such as the oxides and suphides of iron and the oxides and silicates of aluminium and beryllium. The naturally occurring compounds are known as minerals, most of which have been given names according to their composition [e.g. galena---lead sulphide, PbS; sphalerite---zinc sulphide, ZnS; cassiterite---tin oxide, SnO2].

翻译：
金属在海洋中的含量在一定程度上与其在地壳中的 含量有关，因为海洋中的金属来自于地壳岩石的 风化，但另一个影响因素是酸雨对于矿物浸出过 程的影响；因此表1.2中示出的金属在海洋中的 含量并非与其在地壳中的含量完全一致。海底可 能在不远的将来成为金属的重要来源，因为所谓 的“锰结核”不仅含锰，而且还富含很多种其它 金属。这些锰结核在富氧海水中还在不断形成， 尤其是在太平洋海水中。

1.1.2 Metallic ores 金属矿
The abundance of metals in the oceans is related to some extent to the crustal abundancies, since they have come from the weathering of the crustal rocks, but superimposed upon this are the effects of acid rainwaters on mineral leaching processes; thus the metal availability from sea-water shown in table 1.2 does not follow precisely that of the crustal abundance. The seabed is likely to become a heavily exploited source of metals in the near future for the so-called “manganese nodules” are rich in a variety of metals in addition to manganese. These nodules are continuously being formed in oxygen-rich waters particularly in the Pacific Ocean.
