How many millions of years did they make them and then put them … Continue reading Chalkboards and Zander

In little more than a century, we have changed the Earth's skin a bit with our mines, highways, cities, and stuff. Other empires also dissolved mountains … Continue reading Gredos waterfalls
From a geological point of view, the mineral phases that we can find in Miguel Vacas Mine are the classic ones of primary and secondary origin associated with low-temperature hydrothermal vein deposits. These are very likely related to late hydrothermal magmatic fluid circulation processes through the cracks and fissures of pre-existing metamorphic rocks (forming breccias … Continue reading Miguel Vacas Mine. Genesis of copper mineralizations
The crystal-clear waters and strong Mediterranean light allow for a view of the rock and sand bottoms, their green and turquoise colors, and the intense blue of the posidonia beds. Feeling them makes my mind dive into a sea that witnessed the birth of history. Those who brought the fluid of several civilizations sailed these … Continue reading Scuba diving in Cabo de Gata
