title: Early Silurian tholeiitic-boninitic Mailisu ophiolite, South Tianshan, Kyrgyzstan: a geochemical record of subduction initiation

description: Ophiolite assemblages of the South Tianshan fold-and-thrust-belt (STS) track the sea floor dynamics of the late Cambrian to Carboniferous Turkestan Ocean in the western Central Asian Orogenic Belt. We interpret new geochronological and geochemical data for the Mailisu ophiolite from western Kyrgyzstan as evidence for an early Silurian incipient subduction zone outboard the South Chatkal Arc of the Middle Tianshan. Igneous zircons from a leucogabbro yielded a U-Pb age of 440 ± 6 Ma indicating one of the oldest sea floor fragments in the STS. Metabasalt samples have N- to E-MORB trace element patterns and initial ε<sub>Nd</sub> values of ~5 to 9 support melting of depleted asthenosphere comprising a minor OIB component. Cross-cutting diabase dykes show geochemical characteristics of high-Ca basaltic boninites. Their low REE abundances and highly fractionated middle-heavy REE patterns indicate sources that were more melt-depleted than those of the metabasalts. Concave upwards LREE patterns are compatible with a residual peridotite source, fertilised by small-degree OIB-like melts with ε<sub>Nd</sub> of ~5 to 6. Positive Ba, Sr, and Pb anomalies support the involvement of slab-derived hydrous fluids that probably facilitated the melting of the residual mantle. The association of MORB-like metabasalts with younger dykes of boninite affinity suggests subduction initiation for the origin of the Mailisu ophiolite. Our data elucidate one of the major yet little understood episodes in the Paleozoic history of the Turkestan Ocean. Future identification of similar rock assemblages will be helpful to understand the insufficiently constrained history of ocean floor subduction in the Paleozoic Oceans of the western CAOB.

title: Paleoproterozoic metamorphism in the northern Fennoscandian Shield: age constraints revealed by monazite

description: We have identified two contrasting styles of Paleoproterozoic metamorphism in the northern part of the Fennoscandian Shield. The Karelia and Lapland-Kola Provinces, comprising Archean and overlying Paleoproterozoic supracrustal rocks, show a typical medium pressure Barrovian-style metamorphism with commonly found kyanite-bearing mineral assemblages and ITD (isothermal decompression) PT paths. In the juxtaposed Svecofennia Province metamorphism represents low pressure-high temperature Buchan style with garnet-cordierite migmatites and intercalated andalusite-cordierite and andalusite-staurolite schists and sillimanite-muscovite gneisses. The retrograde PT paths show only a moderate uplift during cooling. U-Pb age determinations on monazite were made using the LA-ICP-MS from more than 80 samples from metasedimentary rocks. The sampling covered most parts of the Paleoproterozoic bedrock in Finland. The analyses reveal three peaks at c. 1.91 Ga, 1.86–1.88 Ga and at 1.79–1.81 Ga. The oldest, c. 1.91 Ga monazites are mostly found in the Lapland-Kola Province which is located in the northernmost Finland. In the Karelia Province where the Paleoproterozoic is underlain by Archean bedrock monazite yielded ages of 1.76‒1.81 Ga with only a few older exceptions in samples showing a spread of <sup>207</sup>Pb/<sup>206</sup>Pb ages from c. 1.92–1.81 Ga. The Karelia Province underwent tectonic thickening, where monazite ages of around 1.80 Ga mostly represent exhumation near the temperature maximum. In the Svecofennia Province monazite ages vary from c. 1.89 to 1.78 Ga. In the Western Finland Subprovince the monazite ages in high-grade migmatites are mostly 1.86‒1.88 Ga but within the older migmatite areas there are lower grade zones where monazite yields ages of c. 1.80 Ga. Some samples also show a spread of <sup>207</sup>Pb/<sup>206</sup>Pb ages from 1.89‒1.86 Ga to c. 1.78 Ga. In the Southern Finland Subprovince most ages are either 1.80‒1.78 Ga, especially in the andalusite grade schists, or the sample shows a spread of <sup>207</sup>Pb/<sup>206</sup>Pb ages from c. 1.88 to 1.78 Ga. Only in the eastern part of the Southern Finland Subprovince there are rocks which yield merely 1.86‒1.89 Ga ages. Low pressure-high temperature metamorphism and lack of high or medium P/T rocks in the Svecofennia Province refers rather to accretionary than collisional processes.

title: Životní prostředí (ISSP 2010) - Česká republika

description: Mezinárodní program výzkumů ISSP: ISSP (International Social Survey Programme) je dlouhodobý mezinárodní výzkumný projekt, který existuje od roku 1983. Tento výzkumný projekt je založen na mezinárodní a meziprojektové spolupráci v oblasti výzkumu v sociálních vědách. Je zaměřen na významná témata týkající se postojů. ISSP kombinuje dvě roviny srovnání - srovnání v mezinárodní a v časové perspektivě. Výzkumné aktivity probíhají nepřetržitě v ročních cyklech. Tento výzkum navazuje na předchozí šetření Postoje k životnímu prostředí a k místní politice, které bylo organizováno v roce 2000. Výzkum ISSP 2010 se zaobírá širokou paletou témat týkajících se vnímání životního prostředí, jeho poškozování a ochrany. Datový soubor se skládá ze dvou částí. Jedná se o reprezentativní výběr dospělé populace a nadvýběr mladých lidí do 30 let (boots soubor, viz technická informace). V souboru se dají tyto dvě populace rozlišit s pomocí proměnné "reprezentativní".

Journal of Geophysical Research: Solid Earth, 123(9), 7644-7660.s, http://dx.doi.org/10.1029/2017JB015105". The data is provided in a .zip folder for 2 experiments that are accompanied by a README file for introduction. Files format are Microsoft Excel Worksheet (.xlsx) and data are tabulated. Each file contains the corresponding relevant sample’s details and each column of data is clearly labelled, units included. For each experiment, local time, corrected time, temperature (in degrees Celsius), acoustic emission amplitude (in decibels) and counts were recorded. Cylindrical samples of ‘Comiso’ limestone samples (Ragusa Formation; Sicily) were heat-treated to investigate the effects of thermal stressing on the limestone’s microstructure. In all tests, a controlled heating rate of 1 °C/minute was applied, keeping the specimen at the desired maximum temperature for 30 minutes to allow complete temperature equilibration followed by natural cooling (generally less than&lt;1 °C/minute). The experiments were conducted on the Carbolite CTF12/75/700 tube furnace of the Rock and Ice Physics Laboratory of the University College of London between the 22nd and 28th February, 2016. The experiment were conducted by Drs A. Castagna and J. Browning, both responsible for the collection and interpretation of the data.

Abstract
Thorne–Zytkow objects (TZO) are potential end products of the merger of a neutron star with a non-degenerate star. In this work, we have computed the first grid of evolutionary models of TZOs with the MESA stellar evolution code. With these models, we predict several observational properties of TZOs, including their surface temperatures and luminosities, pulsation periods, and nucleosynthetic products. We expand the range of possible TZO solutions to cover $3.45\( \lesssim\) log (T/Teff) \( \lesssim\) 3.65 and 4.85 \( \lesssim\)log (L/L_sun) \( \lesssim\)5.5. Due to the much higher densities our TZOs reach compared to previous models, if TZOs form we expect them to be stable over a larger mass range than previously predicted, without exhibiting a gap in their mass distribution. Using the GYRE stellar pulsation code we show that TZOs should have fundamental pulsation periods of 1000--2000 days, and period ratios of ~0.2--0.3. Models computed with a large 399 isotope fully-coupled nuclear network show a nucleosynthetic signal that is different to previously predicted. We propose a new nucleosynthetic signal to determine a star's status as a TZO: the isotopologues  \(^{44}\rm{Ti O}\) and \(^{44}\rm{Ti O_2}\), which will have a shift in their spectral features as compared to stable titanium-containing molecules. We find that in the local Universe (~SMC metallicities and above) TZOs show little heavy metal enrichment, potentially explaining the difficulty in finding TZOs to-date.
