Mass fractionation laws, mass-independent effects, and isotopic anomalies
Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …

Constraining the astrophysical origin of the p-nuclei through nuclear physics and meteoritic data
A small number of naturally occurring, proton-rich nuclides (the p-nuclei) cannot be made in
the s-and r-processes. Their origin is not well understood. Massive stars can produce p …

What Martian meteorites reveal about the interior and surface of Mars
A Udry, GH Howarth, CDK Herd, JMD Day, TJ Lapen… - 2020 - Wiley Online Library
Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total
of 262 individual samples originating from at least 11 ejection events. Geochemical …

The Lu–Hf and Sm–Nd isotopic composition of CHUR: constraints from unequilibrated chondrites and implications for the bulk composition of terrestrial planets
The Lutetium–Hafnium radiogenic isotopic system is widely used as a chronometer and
tracer of planetary evolution. In order for this isotopic system to fulfill its potential in planetary …

The geologic time scale
Construction and assembly of the Geologic Time Scale involves:(a) constructing a relative
(chronostratigraphic) standard scale for key periods in the Earth's rock record;(b) identifying …

Hf–W–Th evidence for rapid growth of Mars and its status as a planetary embryo
Terrestrial planets are thought to have formed through collisions between large planetary
embryos of diameter∼ 1,000–5,000 km. For Earth, the last of these collisions involved an …

Hf–W chronology of the accretion and early evolution of asteroids and terrestrial planets
The 182Hf–182W systematics of meteoritic and planetary samples provide firm constraints
on the chronology of the accretion and earliest evolution of asteroids and terrestrial planets …

[PDF][PDF] 7.06-temperatures, heat and energy in the mantle of the earth
Even a cursory historical look at the development of geology reveals that the cooling of the
Earth has always been a central issue (Birch, 1965; Fourier, 1824; Holmes, 1915; Joly …
