TL;DR: In this paper, a systematic review of the progress achieved in this field is provided, based on an analysis of the InSAR Line-Of-Sight (LOS) measurements, i.e., Offset Tracking and multi-aperture InSar (MAI), with which the surface displacement in the azimuth direction can be measured together with the LOS displacement.

TL;DR: In this paper, the impact of fly ash (FA) on plant species and soil quality is investigated. But, the effect is minimal in the case of weathered FA and the results reflected the heterogeneity of ash characteristics, soil types, and agro-climatic conditions.

TL;DR: In this article, the authors present a data compilation of over 70 published Ca isotope studies, totaling over 2600 measurements presented on a common delta scale, that includes data on rivers and groundwater, dust, soils and soil pore fluids, vegetation, rainwater, silicate minerals/rocks, and authigenic marine minerals (carbonates, sulfates, and phosphates, both modern and ancient) and suggest a decaying biosphere has the potential to impact riverine δ44Ca by tenths of a permil over time scales.

TL;DR: In this paper, the authors discussed the theory and development of subsurface heat transport equations for cold and temperate regions and provided analytical solutions to transient forms of the conduction equation and the conductor-advection equation with and without freezing.

TL;DR: In this article, a review of the available approaches available to model the individual stages, or components, of a glacial lake outburst flood (GLOF) event is introduced and discussed.

TL;DR: A review of microtextures from starting point to interpretation can be found in this paper, where a sample preparation procedure using 15% hydrochloric acid and 50g/L tetrasodium pyrophosphate solutions removes most of the grain coatings and adhering particles.

TL;DR: Based on the combination of global sea level change and sequence stratigraphy, the authors systematically investigated the evolution of sedimentary system in the East China Seas (ECS) since the last glacial maximum (LGM).

TL;DR: In this article, the authors present an updated, quantitatively described kinematic reconstruction of the Caribbean region back to 200 million years, integrated into the global plate circuit, and implemented with GPlates free software.

TL;DR: Wang et al. as discussed by the authors show that widespread end-Permian regression took place in whole South China and the timing of the low ebb of this regression was pinpointed to the Clarkina meishanensis and Hindeodus changxingensis zones.

TL;DR: In this paper, geochronological, geochemical and geological data from thirty intrusions are summarised in the Fujian coastal area, and the data provide distinct magmatic, geochemic and tectonic patterns in the area.

TL;DR: In this article, a detailed analysis was made of 63 reported s-A relationships for overland-flow induced gully-heads extracted from data sets collected in various parts of the world.

TL;DR: In this article, the authors provide a comprehensive evaluation and discussion of the various applications of Pb-210(ex) as a tracer in terrestrial and aquatic environments, with particular emphasis on catchment sediment budget investigations.

TL;DR: A review of the current understanding of biomineralization in perforate foraminifera is given in this article, where the authors identify key processes in foraminiferal biominification and formulate hypotheses regarding the involved physiological pathways to provide directions for future research.

TL;DR: There has been a proliferation of methods of quantifying surface roughness in the Earth Sciences, with the aim of facilitating a more systematic exchange of roughness formulations as discussed by the authors, however, a number of issues surround the definition of the term roughness.
