Dendrochronology is one method of this technique.
The mineral Boltwoodite is named after the pioneer of this process who first published it in 1907. SHRIMP is an Australian sector instrument used for this technique. Samarium and neodymium were used in this technique to support the chondritic uniform reservoir model. Zircon and monazite are used in one variation of this technique, which relies on the closure temperature of a mineral. This method was famously used on the Acasta Gneiss (nice) and Nuvvuagittuq (noo-voo-AH-gih-tuke) Greenstone Belt. Dendrochronology is one method of this technique. One element used in this technique is only viable for about 60,000 years due to its 5,700 year long half-life. The term "before present" is used in this process. For 10 points, name this process of determining the age of materials using isotopes like carbon-14.
