Short summary
Distribution of major and trace elements during anatexis at the source area was investigated in a portion of Variscan mid–lower crust exposed at Palmi (Calabria, Italy). Reactive migration of migmatitic melt imparted a mineralogical and chemical signature in mafic rocks associated with migmatites and promoted the crystallization of amphibole by a coupled dissolution–precipitation process. Amphibole and accessory allanite control the distribution of incompatible elements from the anatectic zone.

We present a detailed petrographic, microanalytical and bulk-chemical investigation of 36 mafic rocks from drill hole GT3A from the dike–gabbro transition zone. These varitextured gabbros are regarded as the frozen fillings of axial melt lenses. The oxide gabbros could be regarded as frozen melts, whereas the majority of the rocks, comprising olivine-bearing gabbros and gabbros, show a distinct cumulate character. Also, we present a formation scenario for the varitextured gabbros.

Volcanoes on Earth are divided into monogenetic and composite volcanoes based on edifice shape. Currently the evolution from monogenetic to composite volcanoes is poorly understood. There are two distinct magma chambers, with a deeper region at the Moho and a shallow mid-crustal zone in the Wulanhada Volcanic Field. The crustal magma chamber represents a snapshot of transition from monogenetic to composite volcanoes, which experience more complex magma processes than magma stored in the Moho.

Short summary
The age of formation of buddingtonite, ammonium-bearing feldspar, can be dated with the Ar–Ar method; however, it may often give only minimum ages due to strong resetting. In the studied example it gives a Precambrian minimum age of fossils, associated with this occurrence, and the age of the accompanying mineral muscovite indicates an age near 1.5 Ga. We encourage more dating attempts of buddingtonite, which will give valuable information of diagenetic or hydrothermal events.

In the paper we discuss the origin of large chamber pegmatite bodies which contain giant gem-quality crystals of black quartz (morion), beryl, and topaz. We conclude that these pegmatites develop under the influence of later intrusions of mafic rocks that cause reheating of the partly crystallized granite massifs and that they supply a large amount of fluids that facilitate the
inflationof pegmatite chambers and crystallization of giant crystals of various minerals.

In this paper we calibrate a new empirical clinopyroxene-only thermobarometer based on new models. The new models show satisfying performance in both calibration and the test dataset compared with previous thermobarometers. Our new thermobarometer has been tested on natural clinopyroxenes in the Icelandic eruptions. The results show good agreement with experiments. Hence, it can be widely used to elucidate magma storage conditions.

We developed a new method for quantifying elemental concentrations in natural and synthetic fluid inclusions and gas bubbles using a laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) method with no internal standard. The method may be applied to estimate trace (metal and metalloid) elemental concentrations in hydrous carbonic (C–O–H) fluid inclusions and bubbles with uncertainty below 25 %.

Volcanic activity in the West Eifel region of Germany over the past million years has brought many samples of the Earth's mantle and crust to the surface. The samples from this study are pieces of the deep crust that formed between 264 and 253 million years ago at a depth of ~ 30 km. Samples like these reveal how the Earth's crust has grown and been modified over time.

We present a petrological–geochemical investigation of peridotites of magmatic origin from the Ivrea–Verbano Zone (Italian Alps), a large-scale section of lower continental crust. The main purpose is to provide new insights into the processes governing the evolution of primitive mantle magmas. We propose that studied peridotites were formed by reaction of a melt-poor olivine-rich crystal mush, or a pre-existing peridotite, with upward-migrating melts possessing a substantial crustal component.

Short summary
Two examples of granites in the Variscan Iberian Massif were studied because they are associated with mafic rocks (appinites and vaugnerites), which raise the question of the role of mantle magma in the formation of granitic rocks. We conclude that appinites and vaugnerites derived from melting of different mantle sources, both previously modified by interaction with crustal materials. Subsequent differentiation of appinites and vaugnerites was influenced by contamination with coeval granites.
