REE distribution patterns and isotopic compositions of different types ofrocks can reflect degrees of partial melting and metasomatic processes in the mantle.

不同岩石类型的REE配分模式和同位素组成反映地幔部分熔融程度和交代作用过程。

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。

Various "metasomatic textures" of ores were foimed in diagentic stage.

矿石中的&交代结构&形成于成岩期。

Ore texture mainly is crystallzation texture and metasomatic texture. Ore structure are dominated by disseminate.

矿石结构主要为结晶结构和交代结构，矿石构造以浸染状为主。

The existence of the melt inclusions is a challenge to the conception of traditional contact metasomatic genesis of skarn, and has contributed to the improvements of the research level of genesis of skarns and skarn deposits.

熔融包裹体的存在对夕卡岩传统的接触交代成因观点具有挑战性，有助于夕卡岩和夕卡岩矿床成因理论研究水下的提高。

If magma is involved, metasomatic skarn can be formed, but this kind of skarn is obviously later than the stratified skarn formed under a closed circumstance.

The research on the ore fabric of the main copper-iron deposits in the Tongling district indicates that there are sedimentary-diagenetic, thermal metamorphic and metasomatic ore fabric in this district.

通过对铜陵地区主要铁铜矿床矿石组构研究表明，石炭系铁铜矿床中存在沉积成岩、热变质及热液充填、交代的矿石组构。

The Tonglushan copper-iron deposit,being one of contact metasomatic skarn polymeatal deposit,is at medium risk for use up of its resource after 30 years mining.

铜绿山铜铁矿床是长江中下游铜铁多金属成矿带典型的接触交代矽卡岩型矿床之一，但经三十余年的开采，资源己是中度危机，寻找接替资源，迫在眉睫。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
