Nothing in this show is Random

“Lava is what comes out of volcanoes. That’s superheated peridotite.”

“Peridot…ite?”

“Yeah…it’s made of the same stuff as Peridots.”

This exchange came back to me at random weeks and weeks after it happened. I just wrote it off as an interesting geology lesson and a good opportunity for Peridot to talk about herself, and how she’d changed so far with Steven and the gems. 

But then something nagged at me. Because if I remember one big thing about geology, is that core of the earth is molten iron-nickel, and that it’s why the earth has a magnetic field. 

Guys…

Guys…

Peridots are literally magnetic.

Ancient Water?

Pockets of water discovered deep in a Canadian mine may be 1.5 - 2.5 billion years old. Researchers from the universities of Manchester and Toronto have collected samples of water trapped in bedrock in a Timmins, Ontario copper and zinc mine, about 350 miles north of Toronto. The water was trapped in the rock at a depth of 2.4 kilometers. The rocks in and around the mine were created from a large hydrothermal vent system on an ancient sea floor around 2.7 billion years ago. Three dating methods were used to determine the age of the water, including the measurement of xenon isotopes. Their findings were published in the journal Nature.

Yesterday central Italy was awakened by a 6.2 magnitude earthquake that hit Accumoli (3:36 AM local time), near Norcia, at the border between Umbria, Marche and Lazio regions. The depth of the Earthquake was just of 4km and the destruction in the epicenter was high. The area is known for earthquakes; the most recent are the Aquila earthquake (2009) and the Umbria-Marche earthquake (1997).

At this link it is possible to visualize an interactive map of the event, where the epicenter, the historical seismicity and the shakemap are shown.
