1. Propagation of SH Waves in a Double Non-Homogeneous Crustal Layers of Finite Depth Lying Over an Homogeneous Half-Space
Abstract The present paper studies the Propagation of SH waves in a double non-homogeneous crustal layers lying over an isotropic homogeneous half-space, where upper layer ((i.e. rigidity and density varying trigonometrically with depth) and intermediate layer (i.e. rigidity and density varying parabolically with depth). The wave velocity equation has been o

2. Estimativa de espessura crustal na Província Borborema (NE/Brasil) através de função do recpetor
Crustal thickness and VP/VS estimates are essential to the studies of subsurface geological structures and also to the understanding of the regional tectonic evolution of a given area. In this dissertation, we use the Langstons (1979) Receiver Function Method using teleseismic events reaching the seismographic station with angles close to the vertical. In th

3. Variations in the crustal, lithosphere and mantle structure for the South American platform using P- and S-waves receiver functions / Variações da estrutura da crosta, litosfera e manto para a plataforma Sul Americana através de funções do receptor para ondas P e S
Utilizamos neste trabalho duas metodologias distintas, a função do receptor com ondas P e a função do receptor com ondas S, para mapear variações da crosta e interfaces do manto (litosfera-astenosfera, 410 km e 660 km) em diferentes estações sismográficas na placa Sul-Americana. No estudo da interface litosfera-astenosfera, por ser o primeiro realiz

4. Regional crustal thickness and precipitation in young mountain chains
Crustal thickness is related to climate through precipitation-induced erosion. Along the Andes, the highest mountains and thickest crust (≈70 km) occur at 25° south, a region of low precipitation. Westerly winds warm passing over the Atacama Desert; precipitation is modest in the High Andes and eastward over the Altiplano. Severe aridity, hence low erosio
