🚩 Basaltos Columnares, Valle del Maipo.

Estas son disyunciónes columnares de un flujo de lava basáltica en Cajón del Maipo, Chile, donde las columnas alcanzan decenas de metros de altura y 1 a 3 metros de ancho.
Este flujo de lava es parte de los GeoSitios de Cajón del Maipo, lo que significa un sitio de interés geológico para la enseñanza, el turismo y la ciencia.

These are columnar jointing of a basaltic lava flow on Cajón del Maipo, Chile, where columns reach tens of meters high and 1 to 3meters wide.
This lava flow is part of the GeoSites of Cajón del Maipo, that means a site of geological interest for teaching, turism and science.

La Disyunción Columnar en flujos de lava y depósitos piroclásticos es un fenómeno común dado por el rápido enfriamiento del magma en la superficie de la Tierra. El enfriamiento rápido causa pérdida de volumen y las consiguientes fracturas tensionales en geometría hexagonal perpendicular a la superficie de enfriamiento.

Las diaclasas columnares son comúnmente utilizadas por los escaladores tradicionales en Chile y en todo el mundo porque las fisuras y grietas suelen ser verticales y continuas. ---------------------------------------------------------------------------
Columnar Jointing in lava flows and pyroclastic deposits is a common phenomenon given by rapid cooling of magma in the earth's surface. Rapid cooling cause volume loss and the consequent tensional fractures in hexagonal geometry perpendicular to the cooling surface.
Columnar Joints are commonly used by traditional climbers in Chile and worldwide because the joints and cracks are usually vertical and continuous.

The General Assembly is the biggest international conference on Earth sciences in Europe, organized by the European Geosciences Union. This congress takes place in Vienna Austria. This year it was held from April 7 to 12 and gathered 16273 people from 113 different countries. In the context of the scientific research and outreaching of our activities, three GeoExpedition geologists Valentina, Italo and Francisco, participated in the international congress European Geophysical Union (EGU 2019).
