Back in action, the GOTR folks welcome the only one cannoli, the original paisano, Ken Lazara aka kentonics. We talk field oopsies and dive in a bit into Arizona geology and learn about a very aptly named volcano...you'll just have to listen to find out. We also discuss migmatites and how they fool geologists everywhere. Maybe we even discuss some Metallica disdain. Enjoy and Be cool, stay tuned, and keep it ON THE ROCKS.

It is what it is and that is all that it is!

With special guest, Kentonics!

Be Cool, Stay Tuned, & Keep It On the Rocks!

Episode 47

We dare you to say ‘Ice Aged Ice Sheets’ five times fast. But first, in this episode, the GotR Gang dive into all things Glaciers, brrrr. Glaciers and Glaciation, generally speaking, covers the formation, features, effects, and causes of glaciation events on Earth. Ice sheets and alpine glaciers are described, including their movement and erosional features and landforms. Glacial deposits will be examined, including a discussion of the features created by till and stratified drift. Other effects are worthy of discussion, including crustal subsidence and rebound, sea level changes,

Episode 46!

Welcome to Season 5 of Geology on the Rocks! We have special guest Geoarcheologis Dr. David Rachal in this episode to discuss all things balls. Through his research, Dave uses his balls of choice, Ruppia cirrhosa (Ruppia) seeds, to better constrain megafauna footprints in southern New Mexico along the ancient shorelines of the Paleolake Otero. He draws on both geological and archaeological data to support his research. His work infers a dynamic shoreline rather than the current models, which assume a more static landscape. The study suggests that this newer model could have broader implications for understanding human-megafauna interactions. So take a seat, cozy up with your favorite drink, and listen in as Dave offers a firsthand perspective on his amazing work. As always, between the bars of our main discussion, we present to you another mineral minute and close things out with a new That Freaking Rocks.

Until next time, remember to be cool, stay tuned, and keep it on the rocks!

Episode 45

A season finale! This episode closes out season 4 with a dang bang! We finally get around to answering some of the questions we have received, such as jobs and career paths in the geosciences, what our favorite geologic structures are, identifying minerals in the field, types of rocks you might encounter in various depositional settings. Carly even shares with us a story about what happens when you give her a geology fact. Between the bars of our main discussion we present another mineral minute sponsored by the hydrated phosphouranlyte mineral, Dewindtite.

Until next season, stay tuned, be cool, and keep it on the rocks!

Episode 44!

DANG! What better start to an episode could you ask for as we begin our discussion discussing tornadoes and drunk pigs? Our main topic discusses some of the most common environmental problems we face today. What makes it difficult is the nature of the "problems" have changed: where such problems were once primarily scientific and technocratic in nature, they are now almost exclusively problems of politics. The future of the environment, at home and abroad, appears less certain than ever before even at a time when its potential to bring serious negative consequences for all humanity is more well-known than ever before. Problems that affect large groups and require collective action are recognized as some of the most perplexing political conundrums. Even outside the context of American politics, the environment presents challenges of a unique character. By their nature, environmental problems are ‘big’ problems that likewise affect ‘big’ groups of people and require ‘big’ solutions. Clean air cannot be achieved merely through the regulation of one industry in one part of the country, or through the passion of one highly motivated group or individuals. Between the bars of our main discussion, we present to you another mineral minute and before signing off we close things out with another That Freaking Rocks. Sprinkled throughout are tangents that we navigate in this environmental conscious and inclusive episode!

Until next time remember to stay tuned, be cool, and keep it on the rocks!

Episode 43

In this episode, GOTR takes the skeletons out of their closets and goes on a deep into all things forensic geologies, the mysterious interface between geology and forensics. While there was no exact date when scientific methods were first introduced to solving murders, there is no doubt geology had an early influence. Uniformitarianism is a concept that establishes a crucial link between geologists and forensic scientists, where the use of clues are used to work out a past sequence of events to determine what happened. We go through how a crime scene might be controlled for, and clues are handled. We then cover the various types of evidence forensic geologists might find helpful while finding tangential paths to travel down. Between the bars of our main discussion, we present to you another mineral minute, and on the back half, we close things out with a case full of drugs, government coverups, and murder! So grab your favorite whiskey or drink of your choosing and enjoy!

Whatever you do, remember to be cool, stay tuned, and keep it on the rocks!

Episode 42

This delicious episode explores the amazing world of desserts and wine! We sculpt the the auditory landscape by discussing such musings as climatic conditions that create desserts, geographic distribution of the Earth’s desserts, weathering, dunes, and surface morphologies. We do a little talk on each of our favorite deserts and wind are. We navigate how we can use desserts to explore our not so distant past and explore caves, karsts, coprolites, and wall etchings to see how the desserts we see today are not the desserts of the past. Between the bars of our main discussion we present to you another mineral minutes and instead of a that freaking rocks, we talk about dunes! Come join us and get just as lost in the tangents as we do! Some of our favorite characters make an appearance and we introduce to you a few new ones!!

Until next time be cool, stay tuned, and keep it on the rocks!

Episode 41

It’s snowing down here in the Lone Star State, and geomorphology is the name of this episode’s game, which is fitting as there is a shift in the landscape here at Geology on the Rocks! Geomorphology, simply put, is just the study of Earth’s landforms and landform evolution. Traditionally, the subject has been studied qualitatively, which is the description of landforms, and quantitatively, which is process-based and aims to describe forces acting on Earth’s surface to produce landforms and landform change. And like every other branch of geology, many sub-disciplines within geomorphology include tectonic, fluvial, storm, aeolian, floodplain, glacial, groundwater, climate, tsunami, and many others. Geomorphologists interpret multiple forms of information from various sources to create a logical and rational argument that is appropriately supported by evidence. 

But, of course, much of that is going to depend upon the experience and training of the person (or team) making the interpretations. Therefore, interpretation can be thought of as indeterminate of really not having a definite end result as many interpretations might be valid. Combinations of attributes, relationships, processes, drivers, legacy effects, and sequences of events can create these contingent circumstances that are a complex sequence of events in response to particular events. We go on to discuss what mental faculties it takes to make a less wrong interpretations, and on the back half, we apply those techniques. As always, between the bars of our main discussion, we present to you another mineral minute and close things out with a little friendly competition. Let us know who said it best!

Until next time remember to be cool, stay tuned, and keep it on the rocks!

Episode 40

This episode is dedicated to all those who ever thought that banded iron formations were boring and basic as we here at GotR do a deep dive into these really Spiffy BIFs. We discuss such things as what are they? Where do they come from? Is there any geological significance? What do they tell us? Every time we think that we are going to just have a nice, easy topic, the more and more we read about it and reflect on our own assumptions, it turns out to be so dang complicated and could be several different things at the same time. But we do our best to be as thorough as possible while trying not to get lost in the weeds of this seemingly simple topic. Keep in mind that 1. geology and the history of Earth is a rather complex subject matter, and one should always proceed with caution when interpreting the precipitation mechanisms in BIFs. So take a seat, grab your rock hammers, and favorite whiskey with your favorite podcast duo, and come take an adventure into the wonderful world of BIFs with your favorite podcast!

Until next time remember to be cool, stay tuned, and keep it on the rocks!
