Holocene reactivations of catastrophic complex flow-like landslides in the Flysch Carpathians (Czech Republic/Slovakia)     

Tomáš Pánek  Veronika Smolková  Jan Hradecký  Ivo Baroň  Karel Šilhán 《Quaternary Research》2013

Complex flow-like landslides (CFLLs) are important geomorphic agents of Late Quaternary mountain evolution in the Flysch Belt of the Outer Western Carpathians. The CFLLs are characterised by the upper section of deep-seated, retrogressive landslide of structurally unfavourably oriented rocks and lower sections composed of earthflows originated due to liquefaction of material accumulated from the upper slopes. Radiocarbon dating of organic matter incorporated into landslide debris or related deposits suggests that most of the CFLLs collapsed repeatedly throughout the Holocene with typical recurrence intervals of approximately 1–2 ka. Catastrophic landslides that occurred during extreme hydrometeorological events in recent decades displayed evidence of Holocene activity. Most of the CFLLs dammed and steepened adjacent valleys. Our chronological dataset is biased by erosion of older landforms, but most of the dated reactivations correlate to regional increases in humidity identified by previous paleoenvironmetal studies.  相似文献

Lamellar pyroxenes and their petrogenetic significance: Three examples from the Czech Massif     

Ivo Šanc  Milan Rieder 《Contributions to Mineralogy and Petrology》1983,84(1):73-83

The first event in the crystallization of pyroxenite in nodules from Bory was the growth of clinopyroxene at an uncertain 1,190(30)° C and 2.5(2)GPa. Lamellae of garnet and orthopyroxene in CPX nucleated slightly above 1,000° C and equilibrated at 940(20)° C and 3.9(6)GPa. The growth of lamellae was followed by crystallization of groundmass that corroded lamellar clinopyroxene. Phenocrysts of clinopyroxene and orthopyroxene in olivine pyroxenite from T?i Studně crystallized at 1,290(100)° C and 2.3(1.4)GPa. The lamellae in both phases nucleated between 1,400 and 1,200° C and equilibrated at 860(40)° C and 0.2(3)GPa, before regional metamorphism. (The temperatures of nucleation mentioned rest on uncertain assumptions in the phase-boundary theory and should be viewed with caution.) The serpentinized peridotite-pyroxenite from De?tná contains clinopyroxene relics (the only primary phase) with lamellae of a 1.42 nm sheet silicate topotactically pseudomorphing enstatite, possibly a chlorite or vermiculite. All phases in lamellae are crystallographically oriented in the hosts. The present cases suggest that when applying the theory of phase boundaries, a modified procedure of Robinson et al. should also be considered, in which identity of adjacent areas, rather than just vectors, is the basis of calculation. Spinel lamellae in CPX are bounded not only by faces parallel to coherent interfaces, but also by faces formed by accumulation of incoherent edges of growth ledges.  相似文献

Sul carattere delle tempeste ionosferiche osservate a Buenos Aires     

Prof. Dr. Ivo Ranzi 《Pure and Applied Geophysics》1952,23(1):60-64

Riassunto L'A. espone in forma sintetica i risultati di uno studio sulle caratteristiche delle perturbazioni ionosferiche in Buenos Aires. Durante i mesi invernali la fase positiva delle perturbazioni nella regione F2 appare notevolmente ampia e si nota una stretta correlazione negativa fra la foF2 e la componente orizzontale del campomagnetico terrestre.

Summary The Author reports synthetically the results of an investigation concerning the characteristics of ionospheric storms at Buenos Aires. In winter, the positive phase of the storms in the F2 region appears considerably large, and a close negative correlation is observed between the foF2 and the horizontal component of the terrestrial magnetic field.
