			&lt;br/&gt;&lt;p&gt;Wudalianchi (五大连池) volcanoes are famous Quaternary ones with fairly good volcanic landscape in Northeast China. The volcanic rocks are phonotephrite, tephri-phonolite, trachyandesite, and basaltic trachyandesite with SiO2 contents of 47.3 wt.%–54.2 wt.%. The characteristic of high K2O content in Wudalianchi volcanic rocks suggests that they probably share a common potassic magma source. The magma evolutions of Wudalianchi volcanic rocks are similar, while the new eruption products of Laoheishan (老黑山) and Huoshaoshan (火烧山) volcanoes are slightly more evolved than the old eruption materials, i.e., the magma of the new eruptions in 1719–1721 from the above two volcanoes is the evolved magma in underground chamber. The main phenocrysts of Wudalianchi volcanic rocks are olivines, clinopyroxenes, and some characteristic K-rich leucites...&lt;/p&gt;

			&lt;br/&gt;&lt;p&gt;This article reports a radiolarian fauna from the upper Dalong (大隆) Formation, Pingdingshan (平顶山), Chaohu (巢湖), Anhui (安徽) Province, which includes 15 genera and 23 species. One new species, Copicyntra tongi Gui and Feng n. sp., is described. Comparison of the fauna, lithology and biotic associations with those from Meishan (煤山) D and Dongpan (东攀) sections shows that the Dalong Formation in the Pingdingshan Section is deposited in a deep-water shelf basin, about 60–200 m in depth. On the basis of the biotic composition, diversity and morphology, the microfossil fauna from the Pingdingshan Section can be divided into three sedimentary assemblages and the extinction processes of the assemblages are discussed.&lt;/p&gt;

Concentration-related magnetic parameters, such as magnetic susceptibility (χ), anhysteretic remanent magnetization (ARM), and saturation isothermal remanent magnetization (SIRM) of samples increased in the main roads but appeared lower in the landscape area of the Lushui (陆水) Lake and closely correlated with the concentration of heavy metal Fe, Cu, and Co, and the correlation coefficients are 0.786 for Fe-χ, 0.548 for Cu-χ, and 0.580 for Co-χ, respectively...&lt;/p&gt;

			&lt;br/&gt;&lt;p&gt;Magnetic measurements and heavy metal analyses were performed on street dusts from the main urban area of Chibi (赤壁) City, Hubei (湖北) Province, China. Results revealed that a PSD/MD (pseudo-single-domain/multi-domain) magnetite-like phase dominates the magnetic phases of the street dust. Concentration-related magnetic parameters, such as magnetic susceptibility (χ), anhysteretic remanent magnetization (ARM), and saturation isothermal remanent magnetization (SIRM) of samples increased in the main roads but appeared lower in the landscape area of the Lushui (陆水) Lake and closely correlated with the concentration of heavy metal Fe, Cu, and Co, and the correlation coefficients are 0.786 for Fe-χ, 0.548 for Cu-χ, and 0.580 for Co-χ, respectively...&lt;/p&gt;

The 3-D seismic horizon slices, especially, can play an important role in the sandstone prediction of meandering rivers, distributary channels and low-sinuosity channels.
