VLF-EM and VES: an application to groundwater exploration in a Precambrian basement terrain SW Nigeria
Electromagnetic (VLF-EM) Hard rock environment Groundwater development Layer resistivity Bed thickness mappingss mapping

In a hard rock environment with surface or near surface expression of outcrops, the use of VES only becomes difficult due to its associated problems and limitations. However, the use of VLF-EM becomes...
TRA VELING W A VES IN 2D REACTIVE BOUSSINESQ SYSTEMS WITH NO-SLIP BOUNDAR Y CONDITIONS
TRAVELING WAVES IN 2D REACTIVE BOUSSINESQ SYSTEMS NO-SLIP BOUNDARY CONDITIONS
2014/4/4
We consider systems of reactive Boussinesq equations in two dimensional strips that are not aligned with gravity's direction. We prove that for any width of such strips and for arbitrary Rayleigh and ...
通过正演模拟方式分析音频大地电磁法(AMT)、中心回线瞬变电磁法(TEM)、直流电测深法（VES）对地层的响应特征，结果表明：TEM、AMT对地层的响应特征类似，即对低阻层反应灵敏，而对高阻层的分辩能力较差；VES对高阻层及低阻层的分辩能力相当，相对于TEM、AMT，VES对低阻层的分辩能力差，而对高阻层的分辨能力较高.基于AMT或TEM与VES对地层的响应具有互补的特点，探讨了对AMT或TEM...
Particle Shape versus Coherent Scattering Domain of Illite/Smectite: Evidence from HRTEM of Dolna Ves Clays
Coherent scattering domain Fundamental particle HRTEM Illite/Smectite Mixed-layer crystal

Fundamental particle thickness measurements of Dolná Ves hydrothermal illite/smectite (I/S) samples confirmed earlier findings regarding the content of fixed cations in illite interlayers (ca. 0.9/O10...
Structural Transformations of Interstratified Illite-Smectites from Dolná Ves Hydrothermal Deposits: Dynamics and Mechanisms
Cis-octahedron Illite-smectite Illitization Phase Transformations Trans-octahedron
1996/4/1
Abstract: Structural transformations of illite-smectite samples of hydrothermal genesis with increasing contents of illite layers were studied by X-ray powder diffraction. The samples were K-saturated...
