“…For these analyses, a 193 nm excimer laser-ablation system (RESOlution M50 by Resonetics) was coupled with a quadrupole ICP-MS (XSeriesII by Thermo). Details regarding the performance of the RESOlution M50 are provided by Müller et al [44]. Ablation occurred in pure He (at a flow rate of 0.9 L/min), to which Ar nebulizer gas (at a flow rate of 0.5-0.55 L/min) was mixed downstream of the two-volume LA cell.…”

Abstract:Phosphates from the Martian shergottite NWA 2975 were used to obtain insights into the source and subsequence differentiation of the melt/melts. The crystallization of two generations of fluorapatite (F > Cl~OH and F-rich), chlorapatite and ferromerrillite-merrillite were reconstructed from TEM (Transmission Electron Microscopy) and geochemical analyses. The research results indicated that the recognized volatiles budget of the two generations of fluorapatite was related to their magmatic origin. The apatite crystals crystallized from an evolved magma during its final differentiation and degassing stage. In turn, chlorapatite replaced ferromerrillite-merrillite and was not related to, mantle-derived shergottite magma. The relationship between merrillite and apatite indicates that apatite is most probably a product of merrillite reacting with fluids. REE (rare earth elements) pattern of Cl-apatite might point to an origin associated with exogenous fluids mixed with fluids exsolved from evolved magma. The study shows that, among the three types of apatite, only the fluorapatite (F > Cl~OH) is a reliable source for assessing the degree of Martian mantle hydration. The occurrence of apatite with merrillite requires detailed recognition of their relationship. Consequently, the automatic use of apatite to assess the water content of the magma source can lead to false assumptions if the origin of the apatite is not precisely determined.

“…Выбор оптимального диаметра кратера свя-зан со стремлением к повышению пространствен-ного разрешения и с необходимостью сохранения высокой чувствительности метода и предотвра-щения сильного элементного фракционирования в процессе абляции, которое увеличивается с умень-шением параметра диаметр/глубина кратера. Из-вестно также, что повышение воспроизводимости и снижение неопределенности результатов соглас-но [23,24,[34][35][36][37][38][39] достигается за счет уменьшения объема ячейки лазерной абляции.

“…Laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) "in situ" trace element analyses of pyroxenes from a majority of xenoliths were conducted in the laboratory of the Institute of Geological Sciences of the Polish Academy of Sciences, Kraków Research Centre, using a Resonetics RESOlution M50 excimer laser (ArF; Müller et al 2009) coupled with a Thermoelectron XSeriesII ICP-MS system. Energy density of 8 10 J cm −2 at a repetition rate of 10 Hz was applied.…”

The Oligocene/Miocene basanite from Pilchowice (Sudetes Mts., SW Poland) carries numerous small xenoliths of mantle peridotite, mostly harzburgite. The Pilchowice xenolith suite is dominated by harzburgites and dunites containing olivine Fo 90.2-91.5 (group A). The peridotites of group B (olivine Fo 88.6-89.4), and C (olivine Fo 83.2-86.5) are subordinate. The peridotites suffered from significant melt extraction (20-30%) and were subsequently subjected to metasomatism. Three different trace element compositional patterns of group A clinopyroxene occur, which are typical of silicate melt, carbonatite melt and silicate-carbonatite melt metasomatism, whereas groups B and C were affected by silicate melt metasomatism only. The Pilchowice basanite occurs at the contact of Karkonosze-Izera Block and Kaczawa Complex, two major geological units of Sudetes. The Pilchowice xenolith suite documents underlying lithospheric mantle of composition and depletion degree similar to those described in the whole Lower Silesian mantle domain, which forms NE termination of Saxo-Thuringian zone of the European Variscan orogen. The crustal structure of the orogen is, therefore, not mirrored in the mantellic root.
