petrichor a distinctive scent, usually described as earthy, pleasant, or sweet, produced by rainfall on very dry ground. Petrichor is an uncommon word used in mineral chemistry or geochemistry to describe the pleasant scent of rain falling on very dry ground. Petrichor is a compound of the Greek nouns pétrā “rock, stone” (as in petroleum “rock oil”) and īchṓr, the juice or liquid—not blood!—that flows in the veins of the Olympian gods. About 60 percent of ancient Greek words have no satisfactory etymology; īchṓr is one of them. Petrichor was coined by two Australian chemists, Isabel “Joy” Bear and Richard Grenfell Thomas, in 1964.

A few decades ago, seismologists imaging the deep planet identified a thin layer, just over a few hundred kilometers thick. The origin of this layer, known as the E prime layer, has been a mystery—until now. An international team of researchers, including Arizona State University scientists Dan Shim, Taehyun Kim and Joseph O'Rourke of the School of Earth and Space Exploration, has revealed that water from the Earth's surface can penetrate deep into the planet, altering the composition of the outermost region of the metallic liquid core and creating a distinct, thin layer. Illustration of silica crystals coming out from the liquid metal of the Earth's outer core due to a water-induced chemical reaction. Their research was published in Nature Geoscience.

Why is chalk so pure in composition?

It bothers me that chalk, formed deep in the ocean, is over 90% pure calcite. Where's the Silica? The salt? The gradient between chalk and the bed it formed on? How can a mineral formed over centuries as an enormous bone stalagmite have so few interlopers in it?

my favorite part of oceanic geochemistry was when the professor said “it's MORBin’ time” and then he MORBed all over the trace element depletion signature diagrams

7th Meeting, 15th Session of the Expert Group on Resource Management.

The UNECE Resource Management Week 2024, including the 15th session of the Expert Group on Resource Management (EGRM-15), will be held at the Palais des Nations in Geneva, Switzerland, 22-26 April 2024. Leaders, experts, and stakeholders in resource management will gather to discuss sustainable development challenges and opportunities. Our theme, "Assuring sustainability in resource management", will focus on the United Nations Framework Classification for Resources (UNFC) and the United Nations Resource Management System (UNRMS) and their pivotal role in resource management worldwide. 

Agenda highlights:

Seminars, Workshops, and Short Courses: Focusing on the UNFC and UNRMS as catalysts for transforming raw materials management.

Minerals for the Energy Transition: Highlighting the work of the UN Working Group on Transforming Extractive Industries for Sustainable Development.

Responsible Resource Management: The development and deployment of UNRMS.

Navigating the Future: Exploring various applications of UNFC.

Building capacity: International Centres of Excellence on Sustainable Resource Management.

Empowering Sustainability: Discussing global initiatives and case studies.

Lunchtime lectures: Professor Peter Hopkinson, Co-Director, Exeter Centre for the Circular Economy, Exeter University, and Professor Markus Zils, Circular Economy and Management Science, University of Exeter Business School, UK, on Circular Data (23 April) and Sarah Gordon, CEO, Satarla on The beauty of interconnected natural resource ecosystems, with a focus on ESG issues (25 April).

"A Turkish physicist won an award for revealing the secret of the origin of life"

That was the title of the material on some website. The lecture still never explained the secret of the origin of life, well, maybe I should research the chirality more.

Btw, the chirality concept exists in Eastern European paganism, but just in other words.

Indigenous fire management began more than 11,000 years ago: new research

Wildfire burns between 3.94 million and 5.19 million square kilometres of land every year worldwide. If that area were a single country, it would be the seventh largest in the world. In Australia, most fire occurs in the vast tropical savannas of the country’s north. In new research published in Nature Geoscience, we show Indigenous management of fire in these regions began at least 11,000 years…

God geochemistry makes me feel so stupid

#geochemistry #geology #like I understand the concepts but I really stop there #also petition to my professor to explain something with words instead of mathematics #i am so so confused i want to cry #Help

Having an existential Friday morning with my pot of tea and a 40 minute Welsh historian video. I really loved my job as a logger geologist, and I think my current fears are influenced by their mismanagement and my own fear of failure. But I also cannot deny that I love research. I keep this as a side-hobby and I think it should stay as a side-hobby if I'm sane because doing this for a job would probably make me hate it.

But I'm so scared of going back to a job that takes too much time for me to do this and be happy.

#I also opened my geochemistry homework 1 and my eyes glazed over. I hate isotopes man. I love chemistry. I fucking hate isotopes. #ptxt
