GRADE AND TONNAGE MODEL OF SHORELINE PLACER Ti
By Emil D. Attanasi and John H. DeYoung, Jr.
COMMENTS Grade and tonnage estimates represent mining units rather than individual lenses. Grades are represented as percent TiO2 from rutile, ilmenite, leucoxene, percent ZrO2 from zircon, and percent rare-earth oxides from monazite. Zircon is correlated with rutile (r = 0.49, n = 50), ilmenite (r = 0.58, n = 52), leucoxene (r = 0.55, n = 24), and monazite (r = 0.55, n = 29). Ilmenite is correlated with leucoxene (r = 0.66, n = 24) and with monazite (r = 0.66, n = 29). See figs. 201-205.
