In this study, laser-induced breakdown spectroscopy (LIBS), a sensitive optical technique that can rapidly analyze various elements, is applied to real-time detection and analysis of rock types. Representative rock samples and minerals are selected for spectral analysis and machine learning. The ...
During the industrial processing of kaolin, the ore material is submitted to bleaching treatments with sulfuric and phosphoric acids and metallic zinc, in order to remove colored iron-rich minerals. The effluent waste is initially strongly acidic, and is chemically neutralized with calcium oxide and ...
Because of the thin layer and some factors including lithology, clay, conductive minerals and fracture and so on, the relationship between petroleum and water is relatively complex. Therefore, the resistivity value of oil layer is close to or less than the resistivity value of water layer under ...
combination, high TOC, good pore types (including a high proportion of organic pores, a high proportion of large pores, and the development of micro-fractures in laminae/bedding), high porosity (including fracture porosity), high gas content, and high content of brittle minerals [13,15,16]....
黄金矿砂鉴别方法研究 张庆建,丁仕兵,郭 ,徐兆锋 孙博 刘稚 刘美东 山东出入境检验检疫局,山东青岛266001 摘要:山东某海关检验监管过程中抽检一批黄金矿砂,要求鉴别其产品属性,杜绝不法供应商将掺杂冶炼渣的金矿砂运输至我 国。因此,本文将X射线荧光与衍射分析技术方法联合应用于矿物分析,根据已知元素种类和物相结构,并...

minerals. They also may be found in manymetamorphic rocksformed fromprecursorrocks that contained feldspars and/or the chemical elements required for their formation. In addition, feldspars occur in veins and pegmatites, in which they were apparently deposited by fluids, and within sediments and ...
The on-board identification of ore minerals during a cruise is often postponed until long after the cruise is over. During the M127 cruise, 21 cores with deep-seafloor sediments were recovered in the Trans-Atlantic Geotraverse (TAG) field along the Mid Atlantic Ridge (MAR). Sediments were an...
Rocks and minerals containing groups such as Fe2+ or Fe3+ have characteristic spectral band shapes, which are mainly reflected in the visible bands. Fe3+ has strong absorption in the spectral range of 0.85 μm~0.94 μm and appears as an absorption valley in the OLI 2 and OLI 5 bands. ...
