Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Renewed economic interest in iron oxide–apatite (IOA) deposits—containing tens to
hundreds of millions of tonnes of Fe and substantial amounts of rare earth elements, P, Co …

Kiruna-type iron oxide–apatite (IOA) deposits, an important source of iron, show close
associations with andesitic subvolcanic intrusions. However, the processes of ore formation …

Magnetite-(apatite) ore deposits are interpreted as being formed by the crystallization of iron-
rich ultrabasic melts, dominantly generated by the interaction of silicate melts with oxidized …

Variations in the abundances of light stable isotopes, particularly those of hydrogen, boron,
carbon, oxygen and sulfur, were essential in develo** mineralization models. The data …

The origins of Kiruna-type magnetite (-apatite)[Mt (-Ap)] deposits are contentious, with
existing models ranging from purely hydrothermal to orthomagmatic end members. Here, we …

Abstract On September 12, 2019 at 12: 49: 48 (UT) a bolide was observed by hundreds of
eye-witnesses from the Netherlands, Germany, Belgium, Denmark and the UK. One day …

In this chapter I review some of the knowledge about the oxygen isotope exchange between
air O2, rocks, minerals, melts, including some technical products. The rise of free …

Banded iron formations (BIFs) represent purely sedimentary geological environment, show
macrobandings (1 m–100 m), mesobandings (1 mm–10 cm), microbandings (0.2 mm–1 mm) …

Mantles of rocky planets are dominantly composed of olivine and its high-pressure
polymorphs, according to seismic data of Earth's interior, the mineralogy of natural samples …
