Using the seismic data, drilling, well logging, outcrop and well core, combinedwith the analysis data, the Silurian and Devonian are divided into five seismicsequences and ten logging sequences. The Sq1,Sq4,Sq8,Sq9 and Sq10 are the typeⅠsequence , while the others arethe type Ⅱsequence.
The thickness of layers in different sequences became thinness from east to west. For four grade sequence, this paper pointed C1 under K1y was the smallest in space distribution and only indwelled in southeast of west slope, the C2 above K1y expended more, and the C3, C4, C5 in the K1n distributed out of the basin.
The paper sets up stratigraphic sequence on the base of region geological background, and also studies the burial hill strata spacial distribution characteristics on the base of core describing、stratigraphic dip and imaging log interpretation.
On the basis of systematic analysis of outcrops, well cores, log and seismic stratigraphy, the stratigraphic sequence of the Middle Jurassic in northern Chaoshui basin was divided into 4 third-order sequences and 2 second-order sequences.
The thesis mainly discuss the relationship betweensequence stratigraphy and reservoir of reef and karst, applying Reservoir Geology,well Geology, Seismic strata, Sequence Stratigraphy and other theories to analyze thereef and karst reservoir.
We shall construct a generating set of a nonfinitely generated Ga-invariant ring given in Freudenburg's counterexample by making use of an integral sequence which was constructed inductively by Freudenburg.
The classical Rudin-Shapiro construction produces a sequence of polynomials
A Generalized Sampling Theorem with the Inverse of an Arbitrary Square Summable Sequence as Sampling Points
In this article a generalized sampling theorem using an arbitrary sequence of sampling points is derived.
The mathematical concept of frames is utilized in the analysis of the properties of the sequence of sampling functions.
Using related sequences of Lucas numbers, other 3-manifolds are constructed, their geometric structures determined, and a curious relationship between the homology and the invariant trace-field examined.
This is done using a descending series associated to the complex structure and the Borel spectral sequences for the corresponding set of holomorphic fibrations.
Exact cohomology sequences with integral coefficients for torus actions
It is shown that the one-dimensional sampling sets correspond to Bessel sequences of complex exponentials that are not Riesz bases for $L^2[-R,R].$ A signal processing application in which such sampling sets arise naturally is described in detail.
A fundamental problem with the DWT, however, is the treatment of finite length data sequences.
The analysis of facies associations revealed that the formation was deposited as a symmetrical transgressive-regressive rock succession representing a common stratigraphic sequence.
The bottom of the stratigraphic sequence of the Dzhugdzhur deep-seated granulite complex was determined to consist of a stratified metabasite-enderbite association.
2(a), (b)), reflecting the evolutional difference of oceanic environment and stratigraphic sequence between the upper and lower layers separated by the depth of 160 cm.3.Through a correlation of δ18O values, the core from No.
Human beings' activities on tidal flat have disturbed the vertical distribution of sediments in stratigraphic sequence and accelerated the sedimentation rates.
Measurements of ground resistivity or radar surveys in a raster of 0.5 or 0.5×0.05?m, respectively, are used to gain information on archaeological structures and on the main stratigraphic sequence of sites covering up to 0.5?ha per day.
