1.The scientific study of the origin, history, and structure of the earth. 2.The structure of a specific region of the earth's crust. 3.A book on geology. 4.The scientific study of the origin, history, and structure of the solid matter of a celestial body. ...
The relationship between Quaternary loose sediment stratification and ancient Luanhe alluvial-proluvial fan superposition was investigated in combination with drilling. In excitation using vibroseis, geophone spacing was 5 m, the number of receiving channels was 48, channel spacing was 5 m, blasthole...
A landform diagram provides a window into the past, present, and future of our shared planet. Using the key ideas of uniformitarianism, the law of original horizontally, the law of superposition, crosscutting relations, and unconformities, learn to deduce the progression of a landscape,...
sequence characteristics (symmetrical and repetitive), classifying fold types based on geometric attributes of folds (interval scheduling, strike, and section morphology), optimizing strata based on the superposition principle and area conservation principle, and constructing the polygon features of folds. ...
volcanoes, mineralization, and oil accumulation) that occurred during the evolution of the earth is essential not only for understanding the “abrupt changes in the evolution of the earth”, but also for an in-depth understanding of the co-evolution of material-life-environment of the livable ear...
In this chapter, the principle of the SVM model is firstly described based on the classification model, and then, it is extended to regression problems. The basic principles of the SVM model are as follows: Let me define my matrix m× n, X, and my column vector W, Y, where X is ...
In order to reveal the deformation and failure characteristics and the stability of the rock surrounding the gob–side coal–rock roadway in gently inclined coal seam (GCRICS) under different coal–rock ratios, the deformation characteristics of the surrounding rocks under four different coal–rock ...

The first viewpoint (fig. 2–8B) leads to rigid superposition of an orthogonal three-dimensional grid on the geohydrologic system; while there may be a general correspondence between geohydrologic layers and model layers, no attempt is made to make the grid conform to stratigraphic irregulaties...
Each problem was de-dimensionalized and normalized and all problems were superimposed by using the ArcGIS superposition analysis function and classified into four levels of non-serious, relatively serious, serious and extremely serious by using the natural discontinuity method: 𝑁+=𝑋 − 𝑋𝑚...
