The Alpine Fault Hangingwall Viewed From Within: Structural Analysis of Ultrasonic Image Logs in the DFDP‐2B Borehole, New Zealand

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Ultrasonic image logs acquired in the DFDP‐2B borehole yield the first continuous, subsurface description of the transition from schist to mylonite in the hangingwall of the Alpine Fault, New Zealand, to a depth of 818 m below surface. Three feature sets

On Completely Solvable Lie Foliation [PDF]

open access: yesarXiv, 2018
In this paper we try to generalize the Haefliger theorem on completly solvable Lie foliations. We prove that: every completely solvable Lie foliation on a compact manifold is the inverse image of a homogenus foliation. Every manifold in this paper is compact and our Lie group G is connexe and simply connexe.

Schlesinger foliation for deformations of foliations [PDF]

open access: yesarXiv, 2016
In this article, we show that for any deformation of analytic foliations, there exists a maximal analytic singular foliation on the space of parameters along the leaves of which the deformation is integrable.

On the perfectness of C^{∞,s}-diffeomorphism groups on a foliated manifold [PDF]

open access: yesOpuscula Mathematica, 2008
The notion of \(C^{r,s}\) and \(C^{\infty,s}\)-diffeomorphisms is introduced. It is shown that the identity component of the group of leaf preserving \(C^{\infty,s}\)-diffeomorphisms with compact supports is perfect.

Evaluation of vegetative phenological stages in a spruce monoculture depending on parameters of the environment

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
Vegetative phenological stages were evaluated in a spruce monoculture of the third age class in the region of the Drahanská vrchovina Upland. Methods of the ČHMÚ (Czech Hydro-Meteorological Office) were used. Temperature requirements of Norway spruce for

Surface Foliations with Compact complex leaves are holomorphic [PDF]

open access: yesarXiv, 2004
Let X be a compact complex surface with a real foliation. If all leaves are compact complex curves, the foliation must be holomorphic.

Geology of amethyst quartz deposits from Montezuma and surrounding areas of Minas Gerais and Bahia States

open access: yesGeologia USP. Série Científica, 2023
Amethyst quartz deposits occur in some regions of Minas Gerais state, Brazil, related to different geological environments. The most important are associated with hydrothermal veins crossing the Espinhaço mountain range, mainly in small and eroded ...

On homogeneous composed Clifford foliations [PDF]

open access: yesarXiv, 2015
We complete the classification, initiated by the second named author, of homogeneous singular Riemannian foliations of spheres that are lifts of foliations produced from Clifford systems.

Discrete element analysis of hydraulic stimulation in a slate geothermal reservoir using the ubiquitous foliation model

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
This study employs the discrete element method for a series of coupled hydro-mechanical analyses aimed at investigating the hydraulic stimulation effect on a slate geothermal reservoir.
