查询词典 sedimentation

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

没有什么能比矿石中的杂质更能影响的矿石质量了，矿石是由包括地壳运动，火山喷发，沉积作用，冰川作用，风化作用等地质变迁形成的，在这些运动中，又形成了火成岩，火山混合物，水成岩，沉积岩等，其中还有一些岩石是以共生状态存在的，这就是为什么天然纯净矿石罕见，同时也是急需分离技术和仪器，即矿石加工装置和设备的原因，由于这些还远远未能满足冶金工业的需求，科学家们正竭尽全力试图通过激光分离将选矿技术提升到一个新的高度。

没有什么比矿石形成之前就存在的杂质对矿石品质的影响更为重大。矿石是火成岩、火山群、水成岩、沉积岩等成形时，在包括地壳运动、火山爆发、沉积、冰蚀、风化等地质变化的作用下而形成的。而有些地质变化在一个发展阶段中存在共生现象。自然界无杂质岩石缺乏的主要原因在于需要分离技术和设备来完成，即：需要选矿设备和装置。而迄今为止，这些设备还难以适应冶金业的需要，虽然科学家们尽一切努力用激光分离技术将冶金业提高到一个新的高度。

影响矿石质量的关键是其所含杂质的多少，其成色高低受一系列地质变迁，如地壳运动，火山爆发，沉积运动，冰川运动及风化侵蚀等作用影响，经过高温成岩，火山熔岩，含水岩，水成岩等过程形成，部分以共生态存在。自然界纯矿石稀少，因此我们需要使用分离技术和设备，即筛矿装置和器械，但目前的设备已不能满足冶矿业的需求，科学家们正试图以激光筛选使选矿技术达到一个新的水平。

The study indicates that the Pb and Zn ore-forming elements probably come from the basement rocks; The initial Pb isotope could be derived from the crust-mantle mixing in the erogenic belt; sulfur isotope composition is enriched in heavy sulfur that may have come from the seawater sulfate in the synchronous sedimentation; the ore is characterized with REE enrichment, obvious fractionation of LREE and flat-pattern of HREE; ore-forming media is thermal brine fluid; both mineralization temperature and pressure are low; the metallogenic epoch is probably in late Dengying epoch of Sinian period.

研究表明，基底岩系可能为成矿元素Pb、Zn的主要来源；原始铅主要来源于壳幔棍合的造山带；硫同位素富集重硫，可能主要来源海水硫酸盐；矿石中稀土元素富集，轻稀土分异较明显，而重稀土分异不明显；成矿流体推测为热卤水性质，成矿温度为中低温，具有低压浅成成矿特点；矿床形成的初期应始于震旦纪灯影世晚期。
