We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...

Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Low‐Frequency Raman Spectra of Natural Pyrrhotites: Polarization Dependence for Its Lattice Modes
The present study found low‐wavenumber Raman modes of pyrrhotite Fe1‐xS at ~68, ~87, ~117, and ~230 cm−1 for the first time, thanks to a lab‐built Raman spectrometer, in which the optical path of the incident laser was purged by Ar gas. The sufficiently high signal‐to‐noise and signal‐to‐base ratios enabled us to obtain the polarization dependence of ...

Oxychlorine Species on Mars: A Review
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.
