Minerals Definition and 20 Threads

Minerals in my city water deposit as white uneven layers on the metal bowls typically sold for watering dogs and cats. They also deposit that way on the metal bowls that I use for feeding humans. However on my two Nordicware brand cake pans (used as water bowls for cats) minerals deposit...

I'm modelling the interiors of core-dominated (exo)planets. The EoS I use in my calculations are mostly either a Birch-Murnaghan formulation or a Mie-Grüneisen-Debye formulation. In either case, the ambient density ρ0 at ambient pressure and temperature are required for the implementation...

In the distant future, will it be possible to mine asteroids for valuable raw materials and resources? What kind of materials could be extracted? What about moons and other planets in our solar system?

Would UVC shined onto Potassium cause it to emanate more electrons than its specific work function? Does only the specific work function per mineral cause the mineral to emanate electrons or more energetic sources can also cause it to do the same without using its specific work function?

3D Subsurface Laser Engraving works for clear glasses like Schott BK7 and B9 Borosilicate Glass. How does one do the same for relatively translucent minerals? I have read research papers on using lasers for tattoo removal and cancer radiation therapy. However, I want to know how the laser's...

Are there any type of minerals/molecules/elements even solids that when dissolved, in say a glass of room temp water, can raise or lower the temperature? Examples...

So, I was wondering when will mining seawater for minerals be affordable. The whole process seems very energy intensive to do. Will it ever be a reality one day where we see tritium and deuterium mined alongside lithium and other important elements? I've read somewhere that there are enough...

I have information about temperature, pressure, normal and shear stresses, viscosity, conductivity, density, heat capacity and adiabatic heating for a particular area of mantle in the form of 2D matrices. I want to show phase relation for this region of mantle. Is there an equation (group of...

I just recently read about how we got to know the true age of the Earth but I am a bit confused and curious about one thing. The mineral or rock is initially going to be a uranium right? If it is, isn't all of it going to decay at the same rate? I know that a radioactive reaction is spontaneous...

Lately I'm learning how to identify the most common rock-forming minerals, but I have some doubts about it. First of all, how can I distinguish between massive minerals and rocks? Second thing, a massive mineral from what I understood, has an internal order (so it's not amorphous), but that does...

Can our body synthesize its own minerals and essential elements? I mean calcium, potassium, sodium, phosphorous, magnesium, zinc etc. I know we can have them from our food. Also, can they be stored just as glycogen stores glucose and fat tissue stores triglycerides etc?

Can you help me identify this mineral and rock? I can't. I think the mineral is quartz. I tried the UV light, but it didn't work. (Mebbe it's something precious!) :eek:

I'm going to display my rock and mineral collection in glass door cabinets in the living room. I've found some LED under-the-counter lights, 21 small LED lights per 2-ft string. I plan to use one of the strings for each shelf. They come in two "colors", warm and cool. Sorry, they don't...

I'm worried I'm not taking in enough vitamins and minerals in my body. My daily diet usually consists of white bread, eggs, cheese, chicken or meat, often macaroni or rice, milk, potatoes, and oatmeal. I only consume some vegetables and fruits here and there (and not much either). Does taking...

Homework Statement (4 marks) Instruments that measure the force of the Earth's gravity with great accuracy are carried in airplanes over mineral-bearing landscapes. Explain how readings on the instruments indicate when there is a deposit of minerals or oil below the plane. Homework...

I have been googling as many terms possible, but still not successful in finding a list of diffusion coefficients of common minerals eg; Quartz, Beryl, Spinel, Corundum etc... I will highly appreciate your contributions.

I'm in my physics course right now and recently became interested in mineral deposits and my teacher told me to look into how geologists use the wave nature of light to find mineral deposists.. I am not sure if I am just really confused about the subject or if I just can't find anything but...

This is an interesting product because I know quite a few females who use it and I know some salons even use it. Bare minerals is a makeup kit. They claim it's made from crushed minerals and is actually good for the skin. They also say is free of preservatives, talc, oil, fragrance and other...

what is the difference between a mineral and a cell? is a mineral made out of cells? what is the chemical composition of a mineral as opposed to a cell (preferably the simplest cell, a unicellar organism)??

What is a way to detect minerals through rocks? For example soaking water in some rocks cause the rock to change a certain color to indicate that it has a certain mineral. I'm doing magnesium in lava flows in the island of Hawaii. Yes I live in Hawaii. If you could give me some ideas that would...
