Abstract

The rapid rise in world demand for the rare-earth elements (REEs) has expanded the search for new REE resources. We document two types of light rare-earth element (LREE)-enriched rocks in the Khanneshin car-bonatite complex of southern Afghanistan: type 1 concordant seams of khanneshite-(Ce), synchysite-(Ce), and parisite-(Ce) within banded barite-strontianite alvikite, and type 2 igneous dikes of coarse-grained carbonatite, enriched in fluorine or phosphorus, containing idiomorphic crystals of khanneshite-(Ce) or carbocemaite. Type 1 mineralized barite-strontianite alvikite averages 22.25 wt % BaO, 4.27 wt % SrO, and 3.25 wt % ∑LREE2O3 (sum of La, Ce, Pr, and Nd oxides). Type 2 igneous dikes average 14.51 wt % BaO, 5.96 wt % SrO, and 3.77 wt % ∑LREE2O3. A magmatic origin is clearly indicated for the type 2 LREE-enriched dikes, and type 1 LREE mineralization probably formed in the presence of LREE-rich hydrothermal fluid. Both types of LREE mineralization may be penecontemporaneous, having formed in a carbonate-rich magma in the marginal zone of the central vent, highly charged with volatile constituents (i.e.,CO2, F, P2O5), and strongly enriched in Ba, Sr, and the LREE. Based on several assumptions, and employing simple geometry' for the zone of LREE enrichment, we estimate that at least 1.29 Mt (million metric tonnes) of LREE2O3 is present in this part of the Khanneshin carbonatite complex.

42. Optimal Selection of Global Positioning System Set to Minimize Emitter Location Errors.

Abstract

The use of the Global Positioning System (GPS) as a navigation aid for aircraft attempting to locate a ground based electromagnetic energy emitter is studied. In particular, the satellite geometry which yields minimum errors in the emitter location estimation for four different satellite availability cases is explored. This geometry, in general, is not the same as that which yields minimum aircraft navigation errors. Satellite selection criteria are identified and serve as a basis for selection algorithm development. The research shows that emitter location errors can be significantly reduced by selecting satellites based on the criteria presented in this study. Three satellite performance is found to be nearly as good as that obtained using four satellites and, for the two satellite case, emitter location is still better for some period of time than that obtained using four satellites selected to minimize Geometric Dilution of Precision (GDOP).
