Geology of Greenland Survey Bulletin 190, 25-33 List of all minerals identified in the Ilímaussaq alkaline complex, South Greenland Ole V. Petersen About 220 minerals have been described from the Ilímaussaq alkaline complex. A list of all minerals, for which proper documentation exists, is presented with formulae and references to original publications. The Ilímaussaq alkaline complex is the type locality for 27 minerals including important rock-forming minerals such as aenigmatite, arfvedsonite, eudialyte, poly- lithionite, rinkite and sodalite. Nine minerals, chalcothallite, karupmøllerite-Ca, kvanefjeldite, nabesite, nacareniobsite-(Ce), naujakasite, rohaite, semenovite and sorensenite appear to be unique to the Ilímaussaq complex.

The petrographic relations of EGM change with time and advancing crystallization up from Phase II (differentiated complex) to Phase III (eudialyte complex). EGM is anhedral interstitial in all of Phase II which indicates that EGM nucleated late relative to the main rock-forming and liquidus minerals of Phase II. Saturation in remaining bulk melt with components needed for nucleation of EGM was reached after the crystallization about 85 vol. % of the intrusion. Early euhedral and idiomorphic EGM of Phase III crystalized in a large convective volume of melt together with other liquidus minerals and was affected by layering processes and formation of EGM ore. Consequently, a prerequisite for the formation of the ore deposit is saturation of the alkaline bulk magma with EGM. It follows that the potential for EGM ores in Lovozero is restricted to the parts of the complex that hosts cumulus EGM. Phase II with only anhedral and interstitial EGM is not promising for this type of ore.

For bavenite, leifite/IMA 2007-017, and nabesite, sig- nificant differences in the distribution of H, as compared to the literature using SXD analysis alone, have been found. The benefits of NPD data, even with small quantities of H-containing materials, and, more generally, in applying a combined SXD-NPD method to structure analysis of minerals are discussed, with reference to the quality of the crystallographic information obtained. Keywords: Hydrogen, beryllium, minerals, powder neutron diffraction INTRODUCTION lower cation charge, Be2+ vs. Si4+. Thus, a bridging or terminal Information on crystal structure of minerals, including the O forming part of a Beϕ4 tetrahedron is under-bonded compared localization of light atoms such as H and Be, is of considerable to the equivalent Siφ4 unit leading to the prevalence of Be-OH importance because it allows a better understanding of the min- and Be-F in beryllate minerals (Hawthorne and Huminicki eral behavior under natural conditions.

Cover Igneous layering in kakortokites in the southern part of the Ilímaussaq alkaline complex, South Greenland. The central part of the photograph shows the uppermost part of the layered kakortokite series and the overlying transitional kakortokites and aegirine lujavrite on Laksefjeld (680 m), the dark mountain in the left middle ground of the photograph. The cliff facing the lake in the right middle ground shows the kakortokite layers + 4 to + 9. The kakortokite in the cliff on the opposite side of the lake is rich in xenoliths of roof rocks of augite syenite and naujaite making the layering less distinct. On the skyline is the mountain ridge Killavaat (‘the comb’), the highest peak 1216 m, which is made up of Proterozoic granite which was baked and hardened at the contact to the intrusive complex. The lake (987 m) in the foreground is intensely blue and clear because it is practically devoid of life.
