Study using infrared microtechnique reveals three types of fluid inclusions in rutile:Ⅰ-type aqueous inclusions,Ⅱ-type CO_2-H_2O inclusions and Ⅲ-type CH_4 inclusions. Primary and pseudosecondary type Ⅰ inclusions, as well as Ⅱ-type fluid inclusions, having a range of pressure between 0.6 and 1.3 GPa, were trapped during the amphibolite-facies retrogression stageof eclogites, suggesting that fluids related to rutile mineralization originated from water released during retrograded metamorphism of eclogites.

利用红外显微镜对金红石进行的流体包裹体研究表明,金红石中主要存在三类流体包裹体,即Ⅰ型H2O溶液包裹体、Ⅱ型CO2-H2O包裹体和Ⅲ型CH4包裹体,其中I型原生和假次生流体包裹体和Ⅱ型流体包裹体反映出的压力范围为0.6~1.3 GPa,与榴辉岩角闪岩相退变质作用的压力相当,说明与这类金红石形成有关的变质流体源于榴辉岩退变质作用所释放的水。

On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.

岩石化学、微量元素、同位素地球化学证据都表明,华北、华南地区的火山岩根据源岩和局部熔融程度的不同,可以分为两个原生岩浆系列:一个是源岩为尖晶石二辉橄榄岩,随着局部熔融程度的增加,形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆;另一个是源岩为石榴石二辉橄榄岩,随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明,石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量,土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围,Al释放量一般低于0.40mmol·kg~(-1),铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后,淋溶液pH值急剧下降,此时Al淋溶量明显增加,质子缓冲转向Al缓冲范围,其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少,紫色土在低pH模拟酸雨淋溶下,由于含大量硅铝率较高的易风化原生或次生矿物,盐基释放量高于CEC,但Al释放量未明显增加,淋溶液pH也较稳定,土壤尚处于矿物风化为主的硅酸盐缓冲范围。
