Gaur egungo ikerketa geologiko baten nondik norakoak: Kretazeoko hiperestentsioari loturiko hidrotermalismoaren zantzuak Euskokantauriar arroan

Abstract

Denboraren poderioz ikerketa geologikoak asko aldatu dira. Metodologia berriek jakintza geologikoa nabarmen hobetu dute azken urteotan, duela milioika urte gertatutako prozesuak zehaztasun handiarekin ezagutzera iritsi arte. Kretazeoko Euskokantauriar arroko riftingari buruz, ordea, badaude ziurgabetasun ugari. Arro horretako garai hartako hidrotermalismoa azterturik, azkenaldian bolo-bolo dabilen hiperestentsioa deritzon ereduaren bideragarritasuna aztertzen ari da. Kartografia geologikoan, azterketa petrologikoan eta beste hainbat tekniketan oinarrituriko Kretazeoko hiperestentsioari buruzko gaurko ikerketa geologiko baten nondik norakoak aurkeztea du helburu lan honek.

Over time, geological research has changed deeply. New methodologies have greatly improved geological knowledge in recent years to the point of knowing with great precision the processes that took place millions of years ago. However, there are many uncertainties about the Cretaceous rifting of the Basque-Cantabrian Basin. By analysing the hydrothermalism of this basin at that time, it is being studied the viability of a model that has recently become known as hyperextension. The aim of this work is to show the keys to a current geological study related to the Cretaceous hyperextension, based on geological cartography, petrological studies and other techniques.
