Magnetite is my favorite mineral because it's used by female sea turtles (and some other species) to help navigate the open ocean using Earth's magnetic field to return totheir natal beach to lay eggs some 20 to 30 years after they hatched. Question: The substitution of strontium for calcium in calcite shells in a cold-water environment is very interesting. Can, or do, scientists measure strontium amounts in fossils as a proxy for describing paleo marine environments or as evidence for the environment in which a species lived? I'm a retired paralegal, not a scientist. Thank you for your hard work and excellent presentation.

So interesting ❤

I never got a chance to study science at this level in high school because I was obsessed with the humanities and the arts at that time, and its where my natural talents lie. BUT I started collecting minerals during the pandemic and its brought me to a place of suddenly being interested in stretching my mind past my comfort zone to understand how these beautiful crystals are formed and what they are made of. Thanks for making this information easily accessible for me.

Just started my mineralogy class! This helps a lot get a insight of what is to come! Please continue to post when you can!!! *subscribed* Thank you

Never mind. I just watched the lecture on Strontium isotopic behavior and proxies. Thank you.

Really interesting topic. I was wondering whether you could do a video explaining crystal nucleation in the melt and also precipitation of crystals from aqueous solutions and the underlying thermodynamic aspects. It would be really appreciated.

I'm doing an Environmental Science Course and your videos are tremendous help! You cover things amazingly and also have a really accessible video/presentation style, I have no idea why you aren't rolling in tens of thousands of subscribers yet!

For the quantum numbers, I was thinking that n could be like the size of the orbital, l could be the elongness, is that a word, n=5 and l=0 is a sphere while l=2 stretches into a dumbell, etc. The m quantum # is the direction, that's why they can be equations like x or xy. Diamond and quartz, and even ice are strong possibly because they are all tetrahedral. Maybe that is the strongest bonds between atoms. I heard an interesting theory for van der waals bonds. It's like the electron sloshing around in the atom. At some point the electron is on 1 side creating an attraction.

Yea, thanks for clarifying that about the quantum numbers! Also, that's awesome I never put it together that the strong minerals tend to be tetrahedral, great observation. Also, you are completely right about van der waals forces, the electron density being more one side of the atom than the other creates a dipole! The dipoles then cause attraction between molecules!

As always awesome and informative video from GEO GIRL❤ My favorite mineral is the black opal CN=coordination # =closet neighbors ,[now I'll never forget this abbreviation]

Hello :) I don't have a favourite mineral yet, though it surprises me how I didn't connect geometry and minerals together before ! Thank you 😄 Well, now that I think of it, is graphene considered a mineral ? I think it's made of many sheets of graphite, and its possible use as battery material would make it my favorite if indeed it is a mineral 😁

@GEOGIRL

YES graphene is to my understanding a single layer of graphite (so basically a single sheet of carbon atoms, SO COOL), and if I remember correctly, it is also stronger than diamond! What a great choice! ;D

Can you suggest any field related skill that I can learn in lockdown and will help me after lockdown in geology field study

@GEOGIRL

3 жыл бұрын

Good question, I guess it depends on what area of geology you will be going into. If you lean toward more geophysics/structural geology I would say being able to interpret strike/dip and those types of features is very helpful. But in general, I think my most useful field skill has been interpreting lithologies and depositional environments of rock formations (so stratigraphy). That's a great one to master. Best of luck! :D

No worries! A cation is just a positively charged ion (or particle) and an anion is a negatively charged ion/particle. ;)
