Cover Story: Landform series and their sedimentary deposits are the result of aeolian, mass wasting, cryogenic, fluvial, coastal–marine and lacustrine processes. The mapping of landforms and illustrating the trends and composition of their sedimentary deposits are tools to describe and numerically constrain the land-forming processes and the physical–chemical regime of formation (Eh and pH). Climate zonation and crustal maturity are the exogenous and endogenous “drivers”. This approach bridges the gap between a review and a hybrid manual fed by data generated by field work devoted to applied geosciences in extractive and environmental geology (“E & E issue”). View this paper.

A hydrothermal doublet system was drilled in a fault-related granitic reservoir in Cornwall. It targets the Porthtowan Fault Zone (PTF), which transects the Carnmenellis granite, one of the onshore plutons of the Cornubian Batholith in SW England. At...

First Observation of Unicellular Organisms Concentrating Arsenic in ACC Intracellular Inclusions in Lake Waters

  • Agathe Martignier,
  • Montserrat Filella,
  • Jean-Michel Jaquet,
  • Mathieu Coster and
  • Daniel Ariztegui

In unicellular organisms, intracellular inclusions of amorphous calcium carbonate (ACC) were initially described in cyanobacteria and, later, in unicellular eukaryotes from Lake Geneva (Switzerland/France). Inclusions in unicellular eukaryotes, named...

Adakites, High-Nb Basalts and Copper–Gold Deposits in Magmatic Arcs and Collisional Orogens: An Overview

  • Pavel Kepezhinskas,
  • Nikolai Berdnikov,
  • Nikita Kepezhinskas and
  • Natalia Konovalova

Adakites are Y- and Yb-depleted, SiO2- and Sr-enriched rocks with elevated Sr/Y and La/Yb ratios originally thought to represent partial melts of subducted metabasalt, based on their association with the subduction of young (<25 Ma) and hot oceani...

Experimental studies increasingly often report low-temperature (200–800 °C) and low-pressure (0.05–3 kbar) hydrosilicate fluids with >40 wt.% of SiO2 and >10 wt.% of H2O. Compositionally similar fluids were long suggested to pot...
