Book Description
Fluorite is present as a gangue or associated mineral in many epithermal base and precious metal vein and replacement deposi ts occurring in a wide variety of host lithologies. It also forms in many barren deposits under a diverse set of geological and geochemi conditions. Because fluorite contains trace and rare earth elements, and contains neither oxygen nor hydrogen, several geochemical parameters including fluorite composition, fluid inclusion microthermometry, and OD and 0180 values of inclusion fluids in fluorite can be used to compare and contrast barren and metalliferous deposits. The aim of this study is to assess the potential of using fluorite geochemistry as an exploration tool in the search for base and/or precious metals mineralization. Southwestern New Mexico contains many varieties of both barren and metalliferous deposits and was therefore chosen as a field area. Fluid inclusion microthermometry indicates that most of the fluorite deposits formed from low salinity (0 -7 eq.wt.% NaCl) fluids at temperatures between 100 and 220 °C. A small number of deposits, including the Hansonburg MVT deposit, formed from higher salinity fluids (10-20 eq. wt.% NaCl) at temperatures between 100 and 200 °C. OD and 0180 values of inclusion fluids range respectively from -108 to -27 permil and -9.9 to 5 permil relative to SMOW. Horizontal to sub horizontal trends on a OD versus 0180 diagram suggest that variably-exchanged meteoric waters were responsible for fluorite deposition in most deposits. However, a small component of magmatic fluids can not be ruled out in most districts. The rare earth elements (REE) concentration with individual REE show a broad range ranging from tenths into tens of part per million. REE compositions of fluorites generally react the various lithologies which host fluorite mineralization. Igneous-hosted fluorite tends to have high LREE content relative to sediment-hosted fluorite. Furthermore, granite-hosted fluorites are enriched in HREE over LREE. Thus, fluorites hosted by sedimentary, granitic, and other igneous lithologies can be distinguished from "one another. Small and/or isolated ranges in Sr concentration, Sc/Eu ratio, Tb/Yb ratio, and sign and magnitude of europium anomaly constrain fluorites associated with low salinity base and/or precious metals mineralization. One apparently barren fluorospar distri in southwestern New Mexico contains fluorite with signatures indicative of metalliferous mineralization. For this reason, it is suggested that significant base and/or precious metals exploration potential may exist within this district.
