Single layers of the transition-metal dichalcogenides ${\mathrm{WS}}_{2},$ ${\mathrm{MoS}}_{2},$ and ${\mathrm{MoSe}}_{2}$ were formed as aqueous suspensions by lithium intercalation exfoliation crystalline powders examined x-ray diffraction absorption fine structure (XAFS) spectroscopy. The two-dimensional characteristics these systems readily apparent through absence any (hkl) peaks $(l\ensuremath{\ne}0)$ in strong asymmetry $(\mathrm{hk}0)$ patterns. Indexing patterns with rectangular...
Abstract We describe a natural shear zone with triclinic symmetry, present general model for zones based on examples, and investigate the kinematics strain geometry within such zones. In Roper Lake in Canadian Appalachians, orientation of stretching lineation is oriented approximately down-dip near boundary becomes gradually shallower towards centre. The structures central portion exhibit monoclinic symmetry where poles to both S- C-surfaces, S-surfaces striations C-surfaces all plot great...
Arsenic-rich uranium mine tailings from the Rabbit Lake in-pit management facility (RLITMF) in northern Saskatchewan, Canada, were investigated to determine mineralogy and long-term stability of secondary arsenic precipitates formed iron-rich hydrometallurgical solutions. Total iron concentrations six samples ranged 56 6,000 microg/g 12 600 30 200 microg/g, respectively (Fe/As molar ratios 5.3-303). On basis field diagrams generated pH, Eh, temperature measurements on (mean values 9.79, +162...
The Yiwulushan metamorphic core complex (YSMCC) is situated in the northern part of eastern North China Craton (NCC) that experienced significant lithospheric thinning an extensional regime during Late Mesozoic. We present structural and geochronological evidence to show YSMCC underwent NNE‐SSW extension Jurassic WNW‐ESE Early Cretaceous. started with a sub‐horizontal shear zone referred as detachment (YDSZ) between 157 147 Ma top‐to‐the‐SSW sense. YDSZ was subjected limited doming probably...

Abstract An accurate flow law for dislocation creep of quartz aggregates is critical the understanding continental rheology, numerical modeling lithospheric processes, and interpretation microstructures natural quartz‐bearing mylonites. Despite many decades research, considerable discrepancies still exist among laws determined from different experiments. We demonstrate that key to reconcile these consider pressure dependence activation enthalpy. From existing high‐quality experiments on...
The origin of snowball and sigmoidal inclusion patterns in porphyroblasts is discussed. Snowball garnets are peculiar to shear zones whereas occur both on the limbs folds. There currently two models for development these have been discussed extensively literature. We show that although typical two‐dimensional pattern can be produced by either model, three‐dimensional model‐specific thus providing a distinguishing criterion. applied this criterion all available data find classical which...
Scanning tunneling microscopy (STM), atomic force (AFM), and near-edge x-ray absorption fine structure (NEXAFS) have been used to study the of tetracene films on hydrogen-passivated Si(001). STM imaging with nominal thickness three monolayers (3 ML) exhibits characteristic ``herringbone'' molecular packing known from bulk crystalline tetracene, showing standing molecules $\mathit{ab}$ plane. The dimensions orientation herringbone lattice indicate a commensurate structural relationship...
The structural and vibrational properties of $\mathrm{Ca}{\mathrm{H}}_{2}$ have been examined up to $30\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$ at room temperature. Under ambient conditions, has a $Pnma$ (cotunnite-type) structure. A phase transformation was observed around $15\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$ completed $20\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$. high pressure structure is identified as hexagonal $P{6}_{3}∕mmc$. First-principles calculations reproduced the...
