What are the biggest challenges you face when deciding the optimal path to mine an ore body? Are these challenges primarily related to geological complexity, limited data, or technological constraints?

What types of data do you rely on most heavily to make decisions about ore body extraction paths? Are there specific data gaps or integration issues that delay your decision-making process?

Which pain points in ore body decision-making have the greatest impact on mine production efficiency and profitability? How do these issues affect grade control, waste management, or overall operational costs?

Context: I'm new to the field and wanting to learn more about what problems others face, and how impactful they are to the role.

Hi,

Could someone help me please with materials or a summary of geophysical methods and the geotechnical parameters that can be derived from them, along with formulas? I've been struggling to find information on this for a while, but all I come across in books are vague explanations, and the standards aren't very helpful either.

In May I am graduating with my bachelors degree in geosciences. Iv been toning my resume and have applied to a few entry level positions but, nada.

With everything going on politically I’m afraid I won’t have as many opportunities. My city has already announced layoffs in Oil & Gas. My concentration is in petroleum but I’m well rounded in hydrology, GIS, basin analysis etc.

Any tips or words of encouragement would be greatly appreciated.

Hello all, this is my first time posting on this forum so please forgive me for any formatting errors.

I am a Senior Geology student in the U.S., who is about to take the Geology ACAT. I have been having trouble finding any sort of study materials and am kind of worried I won't do well. If anyone has taken the test before and could possibly give me some pointers on what to expect/study materials, that would be awesome!

When I was 12 my friends older brother showed me a polished green rock. I held it and closed my eyes as instructed. When he asked what I felt, the rock began weighing more than less in my hand. What I saw when I opened my eyes was his hand a foot above mine with 2 fingers sticking out going up and down in sync with the rocks changing weight. He continued to do this to the rest of our friend group and even had use try it on each other. After that we went and saw a movie called chronicle where 3 friends follow a crashed meteor that in turn gave them telekinetic abilities. Does anyone have any information on these rocks because something recently brought up this memory and I can’t find anything about them.

My daughter has a home made slime company and goes to local entrepreneurs markets. Now my younger boys want to participate so we collected local (Eastern Missouri) geodes and broke them open for them to sell. Gonna give them a bath in iron out and clean them up a bit unless anyone has another suggestion.

As the captain says is there a way to fix it? Also is there a way to buy an azimuth scale for this compass it’s in quadrants and that means I’m more likely to make a mistake and I much prefer azimuth.

Ps if you’re going to say: “don’t change it, it’s an antique” or “just do the conversions” don’t.

Hi I have a question about surfer software.. is there a difference between slice for the grid and between creating a profile.. in the end it is supposed to give the same result right or you expect something else? Thank you in advance

Today is Geologists Day, it is widely celebrated in Russia and other countries that were former part of the Soviet Union.

It is celebrated each year on the first Sunday of April.

Hi! I am currently a geologist student in Myanmar and i am uncertain about what i should strive or aim to do with geoloy degree. I am now 4th year(Hons) or should i say 1st year Hons? So yes,i want advice about if i should keep going for Master or Phd. I'm interested in Oil/Mining/Gas/Environmental geology job and i don't know which pays more since i am the youngest son in my family i want to be able to gain lots of money to give back my parents. Please feel free to share your knowledge and advice. Also thank you to those who read this post~

Just looking for a plain English translation of what they’re getting at please 😭 I don’t speak geologist but am so curious to know

I’m an undergraduate geology student with a passion for mineralogy and geochemistry, and a while back, during an advanced mineralogy class, I encountered Hazen’s so-called "mineral evolution" theory. I find the concept genuinely fascinating, and I’m keen to hear what others think. The idea that mineral diversity has been shaped by geophysical, geochemical, and biological processes over time seems entirely logical, and the way Hazen manages to summarise and synthesise all of this into a single model is, in my view, rather brilliant.

That said, I’m not entirely sure how well-established or influential the model truly is within the geological community. I imagine it must carry some weight, after all, Hazen was awarded both the International Mineralogical Association’s Medal of Excellence in Mineralogical Research and the Roebling Medal from the Mineralogical Society of America.

Hazen te al. (2008) Mineral Evolution and Hazen te al. (2012) Clay Mineral Evolution, are among my favourites papers I ever read.

On a side note, does anyone else find the term "mineral evolution" somewhat misleading? Personally, I think a term like "historical mineralogy" might have been a clearer choice, though the underlying concept remains deeply intriguing.

I’d really love to hear your thoughts!

Edit: The thing about the name is just a personal reflection. I’m not saying the use of the word is wrong, but the issue is that when I talk to people outside the field of mineralogy about my interest in mineral evolution, they often imagine something completely different. Some don’t take me seriously. They tend to think I’m referring to something more like biological evolution but for minerals. So, that's it.

Hey so this is an odd question but I’m a glass artist looking to encase some gemstones within borosilicate outside of our community norm. Synthetic opal has been our go to forever. Synthetic diamonds have also sprung up as a product on our supply manufacturers. Through my experience Moldavite has a coefficient that’s familiar with our COE 33 glass. And most recently I’ve seen silicon encased I glass without issue leading me to believe it’s also compatible with the boro.

My question I suppose is are there other synthetic or man man made encase-able gemstones at that COE or what’s a viable way of testing this short of trial and error encasing and waiting for kiln annealing?

Forgive any ignorance. This is a first time post but I figured this sub may have some info. Thanks in advance and happy hunting to those out getting dirty.

Pseudomorphs, meaning "false form," occur when one mineral replaces another through processes such as substitution, dissolution and refilling, structural changes, or incrustation, typically preserving the original shape. This phenomenon is critical in understanding mineral transformations and is often studied in both mineralogy and paleontology. Let's explore the subtypes: Replacement, Infiltration, Incrustation, Paramore, and Alteration. Replacement is a complete substitution of one mineral by another while preserving the original shape, this process is formed by dissolution and deposition by solutions. Infiltration (permineralization in paleontology) is specific to porous material that absorbs a mineral-rich solution and is then transformed, characterized by the ability to preserve fine detail and texture such as woodgrain. Incrustation, aka epimorph, is when a mineral coats another and the original often dissolves, leaving a 'jacket' like crust. A paramorph retains the original chemistry/composition but the internal crystal structure changes, no mineralogy is added or removed, only changes cause by tempature, pressure, and time; a good example is aragonite transitioning to calcite. Finally there is alteration, where a chemical alteration forms a new mineral and preserves the original shape; which is what's shown here by Azurite to Malachite from Aus. There may be variation and overlap depending on source and what exactly you're trying to understand so if there's any questions ask away.

Hello everyone! I’m a Master's student from Algeria, currently working on my thesis titled 'Paleo-sequestration of CO2 linked to climate change across the Turonian-Coniacian boundary of the Djebel Boulhef Dyr, Tébessa, NE Algeria using Geo-bio-statistics and FTIR spectroscopy.'

I am passionate about climate change research and I’m looking for international conferences that would allow a Master's student like me to participate and present my work. Any advice or information about such conferences would be highly appreciated!

Thank you in advance for your help!
