E_2_11 — Snowball Earth Hypothesis

The Snowball Earth hypothesis proposes that Earth's surface was entirely or nearly entirely covered by ice on at least two occasions during the Neoproterozoic era (c. 720–635 million years ago): the Sturtian glaciation (

E_4_16 — Cosmogenic Isotope Dating: Beryllium-10 and Exposure Ages

Cosmogenic nuclide dating (also called cosmogenic exposure dating or terrestrial cosmogenic nuclide, TCN, dating) is a geochronological method that determines how long a rock surface has been exposed at or near Earth's s

E_4_15 — Thermoluminescence and OSL Dating: Beyond Radiocarbon

Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) dating are trapped-charge geochronological techniques that determine the time elapsed since a mineral grain (typically quartz or feldspar) was last expo

E_4_22 — Varve Chronology: Annual Lake Sediment Records

Varve chronology is a dating and paleoclimate method based on counting and analyzing varves — annually laminated sediment layers deposited in lakes (and occasionally in marine or estuarine settings). Each varve typically

E_1_13 — Cosmic Impact Markers: Nanodiamonds, Microspherules, Platinum

Cosmic impact markers are distinctive mineralogical, geochemical, and textural features preserved in geological strata that provide evidence for extraterrestrial impact events — including asteroid/comet impacts and airbu
