Ordovician Orogeny and Jurassic Low-Lying Orogen in the Santander Massif, Northern Andes (Colombia)ures above the wet pelite solidus and an overprinting Jurassic low-pressure metamorphism. The early Paleozoic metamorphism occurred during the Ordovician and produced greenschist to amphibolite facies rocks (Silgará Schist) in the outer and upper parts of the orogen and migmatitic granulite facies rAnticonvulsants 发表于 2025-3-25 07:36:16

Late Cenozoic to Modern-Day Volcanism in the Northern Andes: A Geochronological, Petrographical, ande Cenozoic volcanism (and associated hypabyssal porphyritic plutonism), beginning in the mid- to late Miocene, is the result of subduction-related mantle-derived magmatic activity, superimposed upon a compositionally varied and structurally complex basement during the late stages of the Northern And无畏 发表于 2025-3-26 03:05:46
Diagnostic Structural Features of NW South America: Structural Cross Sections Based Upon Detailed Fiunits, faulting, and folding, as derived from field transects across key areas of the complex Colombian Cordilleran system. The summary presented herein, permits a better understanding of the tectonic, physiographic evolution and temporal genetic linkages within the Northern Andes. It is primarily a不给啤 发表于 2025-3-26 07:56:28

The Romeral Shear Zonend encompasses the main locus of deformation associated with the amalgamation and geological-structural evolution of the Northern Andean region during the Meso-Cenozoic, although as an ancient plate boundary, its origins may be traced into the Late Paleozoic. Today, Romeral corresponds to a km-scale集合 发表于 2025-3-26 19:52:00
