Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Knowledge of temperature and pressure, however qualitative, has been central to our views
of geology since at least the early 19th century. In 1822, for example, Charles Daubeny …

Melting experiments on fertile peridotite KR4003, a 'pyrolitic'composition, were made from 3
to 7 GPa in piston-cylinder and multi-anvil apparatus. Temperature gradients across the …

Experimental clinopyroxenes synthesized at 850–1500° C and 0–60 kbar in the CMS and
CMAS-Cr systems and in more complex lherzolitic systems have been used to calibrate a Cr …

A review of experiments on natural peridotites allows improved constraints on the location of
the mantle solidus. Available constraints on the location of the nominally dry peridotite …

This experimental study examines the effects of variable concentrations of dissolved H 2 O
on the compositions of silicate melts and their coexisting mineral assemblage of olivine+ …

Abstract Models for estimating the pressure and temperature of igneous rocks from co-
existing clino-pyroxene and liquid compositions are calibrated from existing data and from …

This paper reports experiments carried out between 1.5 and 2.3 GPa using synthetic
analogs of the molten peridotite system to investigate the effects of pressure (P), temperature …

This paper presents the results of the first quantitative petrological modelling of abyssal
peridotites. The mantle beneath a ridge may be considered as two regions:(1) the melting …

Our ability to calculate the depths and temperatures at which magmas partially crystallize
can prove crucial as petrologists test hypotheses of magma transport and evolution. Yet …
