For the purpose of identifying silicate minerals in the field, a classification according to their color, density, hardness, and morphology will be appropriate. For the identification of natural and synthetic silicate materials in a well-equipped laboratory a classification according to their X-ray ...
The classification of clay minerals with the help of STA-MS Clay materials commonly contain a considerable fraction of layer silicate minerals that exert a strong influence on the nature of the material. Both the st... Emmerich,K/ Wolters,F. () 被引量: 0发表: 2006年 NUMERICAL CLASSIFICATION...
The conventional geometric classification of the silicates is no longer sufficient to classify the ever-increasing number of determined ionic tetrahedral s... Tibor,Zoltai - 《American Mineralogist》 被引量: 56发表: 1960年 Characterizing the nature of embedded young stellar objects through silicate, ic...
Most are brecciated and many show broken and irregular inclusions of silicate minerals, rich in magnesium. Silvery metallic flakes and veins stand out starkly against the dark silicates, and polished, prepared slices are sometimes reminiscent of the night sky. The breccia-like consistency of mesos...
In this paper, the flotation separation mechanism of silicate mineralsbetween quartz and clinochlore was studied. 本论文研究了粉石英和斜绿泥石两种不同类型硅酸盐矿物的浮选分离机理,考察了反浮选和酸处理提纯工艺在电工电子级硅微粉制备中的作用及机理,优化了各步骤条件,并且制备了电工电子级硅微粉。5...
Genesis and Classification of Red-Yellow Podzolic Soils1 It is suggested on the basis of published data that the main processes in red-yellow podzolic soils are the formation of silicate clay minerals at great de... RW Simonson - 《Soil Science Society of America Journal》 被引量: 22发表: ...
Pegmatites, in general, are a mixture of chemical components derivedfrom crustal and subcrustal sources. Elements and minerals in pegmatites and aplites reflect the source area and the geodynamic setting. Three geodynamic settings, Alpine-type, Variscan-type and Rift-type are prone to pegmatitic ...
Astronomers believe that in the early days of our Solar System, more than four billion years ago, all of the inner planets had molten cores. As our Earth is the largest of the Terrestrial planets (those composed largely of silicate rocks, as opposed to gaseous planets) it likely has a hig...
Mud: The main clay minerals present in the Barra Velha Formation are Al-free Mg-silicate minerals (Tosca and Wright, 2015), formed and preserved in the sub-littoral zones. They do not occur in organic-rich profundal intervals, however, where Mg-clays would dissolve. Dissolution of the clays...
It is evident from the study of mineral species recognition that scholars have shifted from studying mainly silicate minerals [68] to studying a wider range of minerals, indicating that intelligent mineral identification research is growing towards a wider range of uses. Color, spectroscopy, and ...
