Paleowinds inferred from detrital-zircon geochronology of upper Paleozoic loessite, western equatorial Pangea. Major focuses include geochronology, comparative geology, and petrology. The technique is used extensively in isotope geochemistry, geochronology, and in cosmochemistry. Isotopic dating and chemical dating are the two typical methods used in monazite geochronology. The advantage of monazite geochronology is the ability to relate monazite compositions with geological processes. Those rocks usually host economic REE ore deposits, making monazite geochronology important in mining exploration. Zircon geochronology gives good record of ages in cooling and exhumation processes. The objective of monazite geochronology is to relate these monazite forming events/reactions with P-T conditions. It is regarded as the most precise method in monazite geochronology. Zircon is one of the key minerals used by geologists for geochronology. As a marine geochemist, Bada made significant research in geochronology. Common techniques include optical microscopy, geothermobarometry, pseudosections, and geochronology. There has been fieldwork to understand the geochronology of Kanjera. The application of LA-ICPMS in U-Pb geochronology started in the 1990s. Llanquihue Lake's varves are a node point in southern Chile's varve geochronology.
