TL;DR: In this paper, the fine-grained Nd-Sr isotopes of the 10 major deserts and sandy lands in North China and the loess in Chinese Loess Plateau were systematically investigated.

TL;DR: This article used reflectance spectroscopy to characterize the sediments in a 795-cm long core taken from the southeastern part of the lake and found that redness increases at times of increased precipitation, that is, as monsoon strength increases.

TL;DR: In this article, a model that relates pedogenic production of hematite and magnetite to precipitation on the Loess Plateau during the last ∼2.6 Ma was proposed.

TL;DR: In this article, the authors investigate the carbonate biomineralization mediated by the bacterium Bacillus megaterium, a dominant strain separated from a loess profile in China, and conclude that the whole process involves epi- and inter-cellular growth in the local microenvironments whose conditions may be controlled by cell sequestration and proton pumping during bacterial respiration.

TL;DR: Wang et al. as mentioned in this paper investigated the transfer and accumulation pathways of heavy metals in cropland ecosystems, and found that heavy metal levels in soil decreased with increasing soil pH, while rice shoots accumulated heavy metals more readily under low soil pH conditions.
