Get ready to dig deep into the geological weeds with Dr. Jesse Reimink and Chris Bolhuis as they tackle the rock-solid debate about Earth's oldest rocks! Is the Ujaraaluk unit in Northern Quebec truly 4.25 billion years old? Or is it just a rocky mix-up? We meticulously break down isotope geochemistry, hydrothermal beauties, and field observations. Discover how extinct isotope systems shed light on our planet's fiendishly old secrets. Plus, we'll uncover the realities of cross-cutting relationships and metamorphic mysteries. Dive in, and don't get too basalt by the complexity!

Hold onto your rock hammers, folks! 📉🌎 In this episode, we're peeling back the layers (pun intended) of the Isua Greenstone Belt in Southwest Greenland. Tune in as we dive into debates about changing the name of geology classes, virtual Fight Clubs, and the complexities of Earth's ancient rocks. Could sediments, pillow basalts, and potential signs of life from 3.8 billion years ago hold the keys to planet Earth's past? We’ll examine graphite layers and supposed stromatolites (yes, those algal wonders), and their controversies. Geology jargon and some decent rock puns included!

Quartz crystals are often the first example of minerals that people see, and are a source of inspiration for many a young geologist. In this episode, we delve into a comprehensive discussion about quartz, a major rock-forming mineral characterized by its durability and prevalent in various geological environments. Key topics include the physical properties of quartz, the formation and identification of its different varieties like amethyst and rose quartz, and the role of titanium as a temperature indicator. The episode also highlights the use of quartz in learning and its applications in understanding geological processes. Join us as we learn about this beast of the mineral world, Quartz!

Here is a link to the paper we discuss in this episode:

In this episode, we talk about meandering streams.  Why don't rivers flow in straight paths?  As soon as a river flattens out, it begins to meander.  It’s these meanders that manage the energy of the water.  How?  They really do 2 things: 1- they increase the resistance (physics) and 2- they decrease the gradient.  Essentially, the river is changing itself to minimize the energy it expends to maintain a state of equilibrium.  We also get into some detail.  Meanders are not random.  They are directly related to the width of the river and also the radius of the meander curvature.  It's a really cool aspects to river morphology.  

We also talk about things that can start meanders.  And finally, we briefly discuss one of geology's more beautiful features - entrenched meanders.  We hope you enjoy!
