As the world's urban population continues to grow, it becomes increasingly imperative to understand the dynamic interactions between human activities and the urban environment. The development of urban environmental geochemistry has yielded a significant volume of scientific information about geochemical phenomena found uniquely in the urban environment, such as the distribution, dispersion, an...

The 9th national conference on applied geochemistry in China will be held Chengdu, Sichuan province, October 2023, hosted by the committee of geochemistry, Chinese Society for Mineralogy, Petrology and Geochemistry (CSMPG) [...]

Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...

Abstract Hydrocarbon exploration has long been based on such costly and time-intensive methods as geophysical surveys, geological studies, drilling. In recent years, however, researchers have started to consider inexpensive alternatives surface geochemistry for hydrocarbon exploration. Some 100 years ago, the leakage of hydrocarbons onto in form micro- macro-seepages motivated toward drilling a...

We examined the use of dC, TOC and C/N geochemistry of sedimentary organic matter to reconstruct former sea levels and paleoenvironments in the absence of suitable microfossil data. The modern distribution of dC, TOC and C/N of 33 vegetation and 74 surface sediment samples collected from four coastal wetlands in the Thames Estuary and Norfolk, UK are described. The dC, TOC and C/N geochemistry ...
