  The lithospheric mantle beneath the Kerguelen Islands (Indian Ocean): petrological and petrophysical characteristics of mantle mafic rock types and correlation with seismic profiles

  摘要：

  Deep-seated meta-igneous xenoliths brought to the surface by alkali basaltic magmas from the Kerguelen Islands reveal that basaltic magmas have intruded the upper mantle throughout their geological evolution. These xenoliths record volcanic activity associated with their early South East Indian Ridge location and subsequent translation to an intraplate setting over the Kerguelen Plume. The meta-igneous xenoliths sample two distinctive geochemical episodes: one is tholeiitic transitional and one is alkali basaltic. Geothermobarometry calculations provide a spatial context for the rock type sequence sampled and for interpreting petrophysical data. The garnet granulites equilibrated over a pressure range of 1.15 to 1.35 GPa and the garnet pyroxenite at 1.8 GPa. Ultrasonic measurements of compressional wave speed V-P have been carried out at pressures up to I GPa, and densities measured for representative samples of meta-igneous xenoliths and for a harzburgite that represents the peridotitic mantle. V-P and density have also been calculated using modal proportions of minerals and appropriate elastic properties for the constituent minerals. Calculated and measured V-P agree well for rock types with microstructures not complicated by kelyphitic breakdown of garnet and/or pervasive grain-boundary cracking. Pyroxene granulites have measured and calculated V-P within the range 7.37-7.52 km/s; calculated velocities for the garnet granulites and pyroxenites range from 7.69 to 7.99 km/s. whereas measured and calculated V-P for a mantle harzburgite Lire 8.45 and 8.29 km/s respectively. The Seismic Structure observed beneath the Kerguelen Islands can be explained by (1) a mixture or underplated pyroxene granulites and ultramafic rocks responsible for the 2-3 km low velocity transitional zone below the oceanic layer 3, (2) varying proportions of granulites and pyroxenites in different regions within the upper mantle producing the lateral heterogeneities, and (3) intercalation of the granulites and pyroxenites throughout the entire upper Mantle Column, along with elevated temperatures, accounting for the relatively low mantle velocities (7.70-7.95 km/s).

• Model of the homogeneous electrical discharge

  日期：2001.8

  This paper is aimed at the modelling of an electrical discharge controlled by mean of a dielectric barrier, at atmospheric pressure; we focus our study on the homogeneous “regime”. This model is based on the use of equivalent electrical circuits and is taking into account the main phenomena of the discharge. We also offer a method for the determination of the parameters of the model; the comparison of the experimental waveforms with the simulated ones is validating the accuracy of the proposed model in the case of discharges in nitrogen or helium. Our model is exploited to point out the drastic importance of the electrical characteristics of the power supply with respect to the main waveforms of the discharge.

  本文旨在模拟通过介电屏障控制的大气压力下的电气放电，我们将研究重点放在均匀“状态”上。该模型基于等效电路的使用，并考虑了放电的主要现象。我们还提供了一种确定模型参数的方法；实验波形与模拟波形的比较验证了所提出模型在氮气或氦气放电情况下的准确性。我们的模型用于强调电源的电气特性对放电主要波形的重要性。（包括计算机辅助电路设计和分析）
