TL;DR: Water repellency (hydrophobicity) of soils is a property with major repercussions for plant growth, surface and subsurface hydrology, and for soil erosion as discussed by the authors.

TL;DR: Dolomite is not a simple mineral; it can form as a primary precipitate, a diagenetic replacement, or as a hydrothermal/metamorphic phase, all that it requires is permeability, a mechanism that facilitates fluid flow, and a sufficient supply of magnesium.

TL;DR: A review on the tectonics and sedimentation of major sedimentary basins and orogenic belts (Late Proterozoic-Neogene) in the Korean peninsula is presented in this paper.

TL;DR: In this paper, a comprehensive review of the biogeochemical cycling of P within the oceans is given, with particular attention focused on the composition and recycling rates of P in the water column.

TL;DR: In this article, a review of the influence of climate on marine clays in the sedimentary record is presented, focusing mainly on the continental origin of the clay minerals and showing the difficulties of retrospective analysis of the impact of climate change on common marine deposits.

TL;DR: In this paper, a review of the state of the art in dryland fluvial research is presented, highlighting the need for a global review assessing the present state of knowledge.

TL;DR: The South American Platform is defined as the stable continental portion of the South American plate not affected by the Phanerozoic - Caribbean and Andean orogenic zones as mentioned in this paper.

TL;DR: In this paper, the distribution and thickness of the basal Silurian hot shales have been mapped in detail for the whole North African region, using logs from some 300 exploration wells in Libya, Tunisia, Algeria and Morocco.

TL;DR: In this article, the authors investigated the influence of the sediment component relative to that of hydrous fluids generally increases towards the south of the Lesser Antilles volcanic arc and found that the proportions of each component in the different magma types are still debated, as is the importance of crustal contamination in producing their trace element and isotopic characteristics.

TL;DR: In this paper, the role of microorganisms for metal mobility in soil has been discussed and the different accumulation processes that microorganisms perform are analyzed and their potential significance in soil systems is discussed.

TL;DR: In this paper, a detailed miospore stratigraphy was used to date the successive steps of the evolution of the palynomorph distribution in Euramerica and western Gondwana, from the latest Givetian to the latest Famennian, to some extent by climatic changes.

TL;DR: A review of the physics involved in the climate changes of late Quaternary time elude us as discussed by the authors, and the key constraints placed by the records kept in ice and in sediments.

TL;DR: Tephrochronology is the study of volcanic ash (tephra) beds for the purpose of correlating and dating volcanic and other geologic events as discussed by the authors, which is a major source of data on the eruption frequency and geochemistry of large rhyolitic volcanoes.

TL;DR: In this article, the authors reviewed the approaches to couple benthic and pelagic biogeochemical models and concluded that they can be classified into a hierarchical set consisting of five levels, differing in the amount of detail given to the sediment processes.

TL;DR: The petrologic and geochemical properties of chondrules as well as results of experimental studies provide strong constraints on chondrule-formation models as mentioned in this paper, which are consistent with the constraints include various flash-heating models.

TL;DR: In this paper, the authors proposed a uniformitarian approach based on a silica-starved vigorous ocean, which is of limited significance when applied to the pre-Neogene settings, especially in the peculiar planktic habitats of epeiric seas.

TL;DR: In this article, the location and extent of Antarctic subglacial lakes were identified using radio-echo sounding (RES) and satellite altimetry, and the total volume of water held beneath the ice sheet was estimated between 4000 and 12,000 km3.

TL;DR: Bak et al. as mentioned in this paper used a time series analysis to identify Milankovitch cycles and other cycles associated with an oscillating physical system, such as the earth solar system.

TL;DR: The history of rock varnish dating spans almost 20 years from the initial suggestion to use uranium series isotopes through the use of a geochemical ratio (cation-ratio dating) to the current application of accelerator mass spectrometry radiocarbon dating (AMS 14C) as discussed by the authors.

TL;DR: The idea of sheath folds being produced mostly by shearing is not confirmed by the available geological data as mentioned in this paper, however, they are formed by constriction or flattening of folds with curved hinges; the latter are a result either of fold interference or of the constriction in the layering plane.

TL;DR: The surface and near-surface geology, geomorphology and natural resources of Kuwait have been reviewed based on the published work as mentioned in this paper, where the authors identified 15 geomorphic zones and 11 morphostructures from analysis of the surface features of Kuwait.

TL;DR: The Baltic Sea, particularly its southeastern part, is discussed in this article, where investigations of regional character as well as specialized studies in the area are reviewed, and general historical works are presented.

TL;DR: In this paper, a brief outline of recent advancements in turbulent boundary layer research and their consequences in sediment transport and bedform mechanics in aqueous environment under unidirectional current is given.

TL;DR: In this paper, the authors investigated the process and rate of island-arc accretion in the late Proterozoic terrane of the Arabian Shield and concluded that the process was similar to that of island arc in the Phanerozoic eon.

TL;DR: It is realised that authors, editors and publishers should pay more attention to proper use of terms, and it remains the responsibility of scientists themselves to guard against improper terminology and ambiguous writing.

TL;DR: In this article, it is concluded that many of the apparent discrepancies between Quaternary and older rocks either are due to different approaches followed during investigations, or reflect a geologically still immature situation, because destructive agents have had insufficient time to remove material or to obscure specific characteristics.

TL;DR: Awareness of the necessity of environmental protection and nature conservation increases rapidly, in both industrial and developing countries as mentioned in this paper, due to insufficient insight into the complexity of the natural processes playing a role in the various modern environments, partly to unawareness of natural changes that occur in the course of time due to lateral facies changes.

TL;DR: In the past few years, however, there is a strong tendency now to require that the high-level waste disposed of will be retrievable as discussed by the authors, and this provides an irrational context.

TL;DR: In this paper, the authors argue that lack of geological insight sometimes plays a role, which implies that an attitude of effectively wringing out the Earth is not sufficient: more attention for earth-scientific education may turn out to be even more important.
