PPT-Geochronometry-Isotope tracing-Age of the Earth

Geochronometry methods Nuclear synthesis Meteorites Age of the Earth accretion Pb Formation of the core Formation of the core energy considerations Formation of crust Plate tectonics starts. Chapter 6. Isotope Geochemistry. In isotope geochemistry, our primary interest is not in dating, but using the time-dependent nature of isotope ratios to make inferences about the nature of reservoirs in the Earth and their evolution.. Smoke and Fog. What is Ray Tracing?. Recall from Day 1: Computer Graphics is the inverse of Computer Vision, Kajiya Equation. Given 3D data, figure out the 2D image with cameras and lighting. Ray tracing is an alternative solution to the fixed-function/GLSL pipeline (mostly). Stable isotopes are used in CCS to look for leakage of CO2 into overlying aquifers or into the surface environment. What are Stable Isotopes. These are isotope that do not decay over time as the radiogenic isotope do.. Chapter . 5. Meteorites. Primitive. Chondrites (stones). Ordinary Chondrites (H, L, LL). Enstatite Chondrites (EH, EL).
