📍Volcán Maipo, Valle del Maipo, RM
5323 msnm

El volcán Maipo es un estratovolcán (cono) que esta ubicado 2 mil metros sobre la Caldera Diamante, una caldera que se formó hace 160 mil años, dejando depósitos piroclásticos (ceniza y pómez) que cubren Santiago, Rancagua y Mendoza.

📍Maipo Volcano, Maipo Valley, RM
5323 masl

The Maipo volcano is a stratovolcano (cone) that is located 2 2000 meters above the Caldera Diamante, a caldera that formed 160 thousand years ago, leaving pyroclastic deposits (ash and pumice) covering Santiago, Rancagua and Mendoza.

🚩 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).

Algunas fotos de nuestra expedición de la semana pasada. Atravesamos más de un kilometro de profundidad de un reservorio magmático fósil, hoy el plutón San Gabriel, reconociendo sus diferentes unidades que evidencian el mecanismo de emplazamiento del magma: el colapso del techo y la sedimentación de bloques al interior del reservorio.

Some pictures of our expedition last week. We crossed more than one kilometer of depth of a fossil magmatic reservoir, today the San Gabriel pluton. We recognized its different units that show the mechanism of emplacement of the magma: the collapse of the roof and the sedimentation of blocks inside the magma reservoir.

Erupción en Campos de Hielo!!! Cerca del Mariano Moreno, pero no era considerado un volcán. Lo mismo pasó con el Vn Hudson en 1971. Tenemos mucho que aprender de los volcánes en Patagonia, inexplorados y muy interesantes por tener una composición Adakítica!

Eruption in Ice Sheets in Patagonia!!! Near Mariano Moreno, but it was not considered a volcano. The same happened with the Hudson Vn in 1971. We have much to learn from volcanoes in Patagonia, unexplored and very interesting for having an Adakitic composition!

Program of UNESCO Global Geoparks to know and evaluate in the terrain Kütralkura Geopark in the Region of La Araucanía.

Manuel Schilling shared a video: 'I share this report about the mission sent by the UNESCO Global Geoparks Program to know and evaluate the Geopark Kütralkura project in the La Araucanía Region. This mission is part of the process for its international recognition as the first Geopark of Chile. If the evaluation is positive, this territory would be the first Geopark of the entire Andes mountain range and the first to represent the process of subduction of the Nazca plate under the continent of South America.
