As a matter of fact, Ag is an important byproduct in many lead mines and sometimes, galena is mined mainly for the high Ag content in it. Ag may occur as solid solution or as inclusion of other Ag-bearing minerals in the galena.

Great, it looks so easy.

Remember, Galena is not only the principal ore for lead, but also an important ore for silver. Vote Galena.

Shatter cones in a recently discovered Precambrian impact site near Santa Fe, New Mexico. Shatter cones are the result of shock waves generated by the energy of a point source impact. These shockwaves radiate outwards from the point of impact, fracturing rock along the way.

I wonder, aren’t the BIF‘s rather confined to the Fig Tree Geoup ?

A M7.4 earthquake struck the Philippine subduction zone today, causing damaging shaking across much of Mindanao. Several people have died.

This is the Philippines' second deadly earthquake in two weeks. Are the events related? And how does this quake compare to the nearby M7.6 in 2023?

Made this figure for a book chapter on tectonic reconstructions that I'm writing with Jonny Wu, using a fantastic field photograph of Joao C. Duarte, of the Telheiro Beach section in SW Portugal.

The formation, heydays, and breakup of the supercontinent Pangea caught in one photograph.

The last one, with the garnets, is this an eclogite?

This is great, BUT the year we burned the most coal was 2024 and it's still going up.

Meet our #September feature Hannah Büttner in this year’s #calendar 2025! 👩🏻‍🔬 She explored fungal-bacterial symbiosis, loves both music & art, and carries science in her bag wherever she goes. 🎒🏜️ Read her interview here: lmy.de/FUIJC 🎙️

#FacesOfScience #LeibnizHKI
A young woman with glasses sits on a wooden bench outdoors, smiling at the camera while holding a viola on her lap. She is wearing a black top, wide green pants, and black heeled sandals. On the left side of the image, there is a large colorful speech bubble with the following quote: “I primarily focused on the symbiosis between fungi and endosymbiotic bacteria. We identified natural products produced by the bacteria that protect the fungi from predators and play a key role in the symbiotic relationship.” At the bottom left, the “Leibniz-HKI” logo is visible. At the bottom right, a large purple arrow points to the right. A graphic calendar page with a turquoise-blue gradient background. In large pink letters it says “SEPTEMBER,” and underneath: “Hannah Büttner.” At the lower left is the “Leibniz-HKI” logo with the text “Leibniz-HKI Calendar 2025.” At the lower right, the word “SWIPE” is written in bold black letters next to a large purple arrow pointing to the right. A young woman in a white lab coat is working in a laboratory. She is holding a pipette and placing a sample into a scientific instrument. On the right side of the image, there is a speech bubble in a turquoise color gradient with the text: “I particularly enjoyed structural elucidation and analytical challenges.” Below, the logo of LEIBNIZ-HKI is visible. A large purple arrow points to the right. A young woman with glasses, wearing a black t-shirt and green trousers, stands indoors next to a large aquarium full of fish and aquatic plants. She holds a viola under her arm and looks thoughtfully into the distance. Her reflection is visible in the aquarium glass. Colorful text bubbles on the right side of the image read: “I like it when Art and Nature come together.” The words “Art” and “Nature” are highlighted in bright, decorative fonts. At the bottom left corner, the logo “LEIBNIZ HKI” is visible.

#Kyanite forms distinctive blades in metamorphic rocks, recording metamorphic temperatures in mountain building events. It is used in ceramic and porcelain technology, clay texture and glazes, and even faceted gemstones.

Although molybdenite is most useful for technical purposes, it’s dioptase that attracts simply by its beauty.

#Carpathite is composed of hydrothermally deposited coronene. Coronene is also proxy for wildfire activity, a function of terrestrial biomass, atmospheric O2, and ignition sources like lightning, volcanoes, and bolides. The oldest known occurrence on Earth dates to the early Ediacarian.

⚒️ 🧪 Another big addition to the remarkable M8.8 earthquake sequence offshore Kamchatka: a M7.8 - the biggest aftershock so far.

With foreshocks, aftershocks, aftershocks of foreshocks, and foreshocks of aftershocks, it's hard to keep these earthquakes straight! Read more about what's going on:

Such a beautiful blue color as that of #hauyne can’t be matched, even if crystals are usually very small.

A difficult choice, as both minerals make wonderful crystals. Yet my favorite is #Kyanite

The huge minerals collection “terra mineralia” in Freiberg/Sachsen, Germany, is certainly one of the most respected minerals museums worldwide, a true gem and must-have-been for any lover of minerals. Besides, the small town Freiberg is a good place for a stay.

Did Earth’s first continents form in subduction zones?

Me and Alan Hastie think so!

Why? Read in detail here in Journal of Petrology doi.org/10.1093/petr...

The take home: Melting @ < 60km ➡️ No rutile ➡️ no Nb anomaly ➡️ no continental crust signature.

Rutile + garnet only stable at ≥60 km.
Subduction Origin of the Nb Anomaly in Earth’s Oldest Continents
Abstract. Earth is unique in the solar system in having plate tectonics, which controls the growth of life-sustaining continents and the habitability of ou
