EXPLORING IGNEOUS ACCESSORY MINERAL TEXTURES: TITANITE FROM NOTCH PEAK GRANITE AND LITTLE COTTONWOOD STOCK, UTAH

Na2O+K 2 O-CaO (wt%) SiO 2 (wt%) Calcic Alkalic Alkalicalcic Calc-alkalic NP LC LCeTitanite is an accessory mineral in many granites.Due to its incorporation of a wide variety of trace elements, low elemental diffusion rates, and relative abundance, titanite is useful in the study of petrogenetic processes.In addition, titanite also retains clear growth zoning from past events.We sampled titanite from two localities, the Notch Peak Granite located in Western Utah, and the Little Cottonwood stock located near Salt Lake City, Utah in order to evaluate Titanite textures in interpreting magmatic and hydrothermal histories.
