Numerical methods in the analyses of small scale texture feature of amalgamation- surfaces by computerized X-ray tomography

Abstract

The amalgamation surface as a result of changing in the arrangement of texture is one of the least frequently examined phenomenons of sedimentary petrology.

The amalgamation- and erosional surfaces can be treated as relatives according to their genetics.

But in most cases the exact identification, making clear distinction between these surfaces and interpretation of them is not obvious.Thus we should deal with these conflicts as well.

Nevertheless we can deal with the question whether the amalgamation surface can be influential to small scale fluid flows. Indeed, because of small scale examination, the results can be helpful in analyzing only small scale fluidflow simulations.

The aim of research is addressed to find answers for more questions in this field:

1. Does the definition of CT provide such obvious information which is helpful in seperating the amalgamation surface from its surroundings?
2. Do the applied research methods provide information about the circumstances of deposition and of transporting?
3. Can be shown other effect besides the circumstances of energy which are influential to the texture of sediment?

Because of the erosional origin the numeric difference of texture can first of all be expected to appear above and below the amalgamation- and erosional surfaces.

The question is the manifestation of these differences in the spatial continuity features of the sedimentary texture.

Can the developing process of the amalgamation surface cause deviation in the parts taking place above and below the surface?

What source of differences can be experienced along the surface?

At the present state of the surveys the results of examination could not be representative. It should be regarded as a first step of a series of examinations.
