Diamonds reveal hidden chemistry deep inside Earth

September 23, 2025 0 Comments Caving, Climate, Geochemistry, Geography, Geology, Global Warming, Mining, Weather

South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts infiltrated reduced rocks, trapping both the cause and effect of diamond formation. These reactions help explain volatile-rich magmas like kimberlites, linking mantle chemistry to volcanic processes. Diamonds emerge as tiny record-keepers of Earth’s deep, dynamic engine.

GIS-based analysis of fault zone geometry and hazard in an urban environment

October 24, 2019 0 Comments Earth Science, Earthquakes, Geoengineering, Geography, Geology, Landslides, Natural Disasters, Oceanography

Typical geologic investigations of active earthquake fault zones require that the fault can be observed at or near the Earth's surface. However, in urban areas, where faults present a direct hazard to dense populations, the surface expression of a fault is often hidden by development of buildings and infrastructure. This is the case in San Diego, California, where the Rose Canyon fault zone trends through the highly developed downtown.
