Much work has been undertaken quantifying the abundance of phyllosilicate clay minerals
in soils, sediments and rocks of Earth's crust. However, no detailed global compilation of …

Pedogenesis models should give us answers to: how does soil form, how does it evolve,
where does it come from and how long does it take to reach this state? This paper reviews …

Ion adsorption-type rare earth element (REE) deposits are the predominant source of heavy
REE (HREEs) and yttrium in the world. Economic examples of the deposits are confined …

Soil‐covered upland landscapes constitute a critical part of the habitable world. Our
understanding of how they evolve as a function of different climatic, tectonic and geological …

K-feldspar is a common detrital mineral in sandstones. It contains little U or Th, and hence
the common Pb isotope composition of unaltered K-feldspar is that of the source rock. Pb …

Clays and clay minerals are the most abundant natural reactive solids on the Earth's surface.
This comprehensive review considers clay science in the context of the Critical Zone-the …

Ophiolites often form complex, fractured, multi-lithological and highly compartmentalized
aquifers that are difficult to characterize. Groundwater chemistry reflects water-rock …

Models of soil genesis are potentially of great importance in assessing the effects of global
change on ecosystems, and may also contribute to our understanding of soil genetic …

This study was conducted to evaluate the weathering intensity of the major soils developed
on igneous rocks in semiarid region of northwestern Iran. Eight parent materials were …

Plants play an important role in Silicon (Si) cycling of terrestrial ecosystems. However, how
plant Si is related to soil Si translocation and transformation in subtropical areas with ample …
