Locating Basalt in the Goldich Dissolution Series: A Mineralogical Investigation
Geology & LandformThe Goldich dissolution series is a widely used concept in geology that describes the order of mineral dissolution in water. The series is based on the relative stability of minerals under typical surface conditions and helps predict the order in which minerals will dissolve and release their constituents into groundwater. The Goldich dissolution series is

Isotopic Signatures: Naming a New Phenomenon in Earth Science
Geology & LandformThere are many phenomena in the Earth sciences that remain unnamed or poorly understood. The discovery of a new phenomenon can be a major breakthrough, but it also poses a challenge to scientists: how to name it? The name of a phenomenon should be descriptive, concise, and memorable. In the case of isotopic signatures, the

Isotopic Verification Unveils Accuracy of Ice Core Temperature Reconstructions
Geology & LandformIce cores are long cylinders of ice drilled from glaciers and ice sheets that provide a record of past climate change. One of the most important climate variables that can be reconstructed from ice cores is temperature. This is done by measuring the isotopic composition of the ice, which reflects the temperature at the time

Exploring the Contrasts: Depleted vs. Enriched Mantle in Magmatism
Geology & LandformThe Earth’s mantle is a layer of the planet that lies between the crust and the core. It makes up about 84% of the Earth’s volume and is composed of solid but fluid rock. This layer is extremely important to our understanding of the planet’s geology and is responsible for a number of geological processes,
