  feldspar
The rocks are classified into greywackes or feldspar sandstones, grains of which are the mixtures of mafic rocks, felsic rocks, and quartz+calcite.
      
In conjunction with high abundances of Ba and Sr, as well as low abundances of Y and HREE, these patterns suggest a feldspar-poor, garnet±amohibole-rich fractionation mineral assemblage.
      
Empirical relationships describing the composition dependences of the chemical durability of glasses in the diopside-albite, diopside-anorthite, diopside-orthoclase, diopside-quartz, and diopside-feldspar systems are derived.
      
Two glasses of the same chemical composition manufactured while using two different sources of aluminosilicates: (1) sodium feldspar and (2) volcanic tuffs have been compared [1].
      
The influence of bacterial activity on glauconite formation is supported by the study of dissolution zones on quartz and feldspar grains, which revealed biomorphic structures akin to fossilized bacteria.

Five inorganic minerals commonly found in coal, such as koaline, feldspar, quartz, pyrite and ironstone, were separately mixed up with the uranium oxide (U_3O_8) powder or the solution of (NH_4)_4UO_2 (CO_3)_3.Each of the mixtures was calcined at different temperatures (in the range of 300—1100℃), and then the calcined products were subjected to leaching tests, X-ray diffraction analysis and determination of apparent density.It has been shown that the apparent density of the calcined products increases with...

Five inorganic minerals commonly found in coal, such as koaline, feldspar, quartz, pyrite and ironstone, were separately mixed up with the uranium oxide (U_3O_8) powder or the solution of (NH_4)_4UO_2 (CO_3)_3.Each of the mixtures was calcined at different temperatures (in the range of 300—1100℃), and then the calcined products were subjected to leaching tests, X-ray diffraction analysis and determination of apparent density.It has been shown that the apparent density of the calcined products increases with the increase of calcining temperature, and that uranium leaching by conventional acid decreases with the increase of calcining temperature because uranium is locked up within its calcined products.

本文用八氧化三铀粉末和三碳酸铀酰铵溶液,分别和煤中常见的五种无机矿物——高岭土、长石、石英、黄铁矿、褐铁矿等混合制得的人工配料,在300—1100℃温度下焙烧,对焙烧产物进行了浸出、松装密度测定和X射线衍射分析。由分析结果提出了温度升高铀浸出率下降的原因是由于铀被无机组份烧结-包裹所致。

The sorption behaviour of Cs+, Sr2+, Eu3+and Ce4+on the surface of Feldspars, Muscovite and Hornblende using X-ray photoelectron spectroscopy is studied. The chemical shifts of oxygen in different minerals are observed and the sorption mechanism is discussed.

用X射线光电子能谱(XPS)初步研究了Cs,Sr,Eu,Ce在长石、云母、角闪石表面的吸附行为。通过观察矿物中氧结合能谱的化学位移,对吸附机理进行了初步探讨。

In this paper a new pulse sampling apparatus is employed. It can be used to determine Na and K in feldspar by flame atomic absorption spectrophotometry. The experiments showed a satisfactory analytical results of two ways sampling method were simultaneously obtained. The linear scope is 1—2 time wider than the conventional way. The analytical speed, the precision and the sampling volume are all superior than conventional way, except for sensitivity and detection limit.
