Application of Image Principal Component Technique to the Geological Study of a Structural Basin in Central Spain
نویسندگان
چکیده
We describe a method to obtain the principal components of a multispectral image. It allows a simultaneous radiometric enhancement by means of a suitable finer level quantization that does not introduce artifacts. Using this method we are able to produce good photographic prints pf the principal components of LANDSAT MSS images. As a matter of fact the twn first components (that we call bands A and B:) alone' contain nearly all the information existilDlg; on th>e: original image while the other contain only no&se. We use this technique to help in the geological study of Campo Aranuelo Basin, in Central Spain aimed to confirm the hypothesis of different geological histories since Miocene times of this area and the remainder of Tajo Basin.

The Dehaj area, located in the southern part of the Urumieh-Dokhtar magmatic belt, is a well-endowed terrain hosting a number of world-class porphyry copper deposits. These deposits are all hosted in an acidic to intermediate volcano-plutonic sequence greatly affected by various types of the hydrothermal alterations, whether argillic, phyllic or propylitic. Although there are a handful of hithe...

The Sivas Basin is one of the most well known major Tertiary basins of the Anatolia connected with the evolution of the Neotethyan Ocean. Central Anatolian Thrust Belt contains realms of this ocean and bounds the basin from north. Therefore, realms of the Inner Tauride Ocean are also surrounded the basin from southeast and represented with allochthonous units. Axis of the eastern section of thi...
متن کاملPixel selection by successive projections algorithm method in multivariate image analysis for a QSAR study of antimicrobial activity for cephalosporins and design new cephalosporins
Thirty-one Cephalosporin compounds were modeled using the multivariate image analysis and applied to the quantitative structure activity relationship (MIA-QSAR) approach. The acid dissociation constants (pKa) of cephalosporins play a fundamental role in the mechanism of activity of cephalosporins. The antimicrobial activity of cephalosporins was related to their first pKa by different models. B...
