Clay minerals are the characteristics minerals on the earth found near planetary surface (the surface where the outer crust of the object comes in contact with atmosphere) environment with variable amount of ions like iron, magnesium, alkali metals, alkaline earth metals and other cations. They are...
The Wulfenite crystals in the central part of the piece are relatively large, averaging under a centimeter, however, the crystals on the two sloping edges of the specimen are big and vary in size from 1 and 1.5 cm and show subtle "sandwich" zoning that this locality is known for. These ...
Selenium concentrations in most plants remain usually low except in “Se-accumulator” plants, typically those who belong to Brassica and Allium families, which can tolerate Se concentrations up to 103 times higher than usual plants (Dumont, Vanhaecke, et al., 2006). This particularity comes ...
As new information comes forth, the mineral data will be upgraded. We will be updating this info quite often to keep abreast of the constantly changing ideas and research results. ADDITIONAL NOTE: Some of the information on the basic information on minerals was referenced fromRARE EARTHS – Forb...
This piece is dedicated mainly to Chinese minerals, including a number of Mt. Xuebaoding pieces, though there are a few Pakistani and other items mixed in as well. I have not included any Inner Mongolian pieces in this update-- the bulk of the material comes from finds made in past ...
Dietary iron is found in two forms—heme and nonheme. Most of your nonheme iron comes from plants. Meat is a source of both types of dietary iron. MAGNESIUM What is it? A macromineral that plays a role in over 300 enzyme systems in your body. ...
When it comes to chiral crystals, all of these alternative building blocks are chiral as well, because a chiral environment always induces to some extent its chirality in its own building blocks. 2.7. Conglomerates and Racemates Solutions or melts from which (non-biological) chiral crystals form...
These factors are reinforced in the International Energy Agency’s (IEA) World Energy Outlook Special Report, which states “the largest source of demand variability comes from uncertainty around the stringency of climate policies”3. Current analyses include at least 30 energy transition minerals and...
This new list comes at an interesting time, to say the least. The US is reliant on totalitarian regimes with dictators installed for life for 32 of 47 minerals — an eye-watering 70%! We are of course talking about China (23) and Russia (9). ...
whether it comes to food intake or to supplements. This has been only a short overview regarding vitamins and supplements and this is summarized in the table below as well. However, there are very good other websites that discuss this topic in much more detail. Here is one that gives anov...
