radioactive elements like U, Th, and K. These radioactive elements decay over time, emitting radiation6,7. The specific mineral composition of granitic and alkaline rocks, which often includes minerals like zircon, monazite, allanite, thorite, apatite and uraninite, can also influence their radi...
Geology and Minerals: This locality occurs in miarolitic granite and these crystals are over 200 million years old. The minerals at this location formed at the contact between the Conway granite and the Moat Mountain volcanics. These volcanic rocks were part of a very active ancient volcano. ...

In this study, we report new API data from early Pliocene volcanic units (“Jinchon Basalt”, ~ 4‒5 Ma) in Baengnyeong Island, Korea, to fill the gap in the current global API database. Analyzed samples, containing MD magnetic minerals, are taken from two units of the same age (...
Old magazines like “Rockhounds” and “The Mineralogist” are great resources, as well as old and current issues of “Rocks and Minerals” and “Rock and Gem”. All of these can be found for sale on eBay and at various mineral shows around the united states. You never know when you ...
During underground flow and depending on the residence time, there is an exchange of ions between water and rocks. The weathering of minerals in these rocks also releases mobile elements (alkali and alkaline earth) and trace elements into the waters [6,7]. These elements form an organo-...
