Ķīmiskais sastāvs:(A. Krzesinska, UOslo) EPMA results indicate well equilibrated olivine with Fa24.4 (Fa23.9-25.1, n=23), orthopyroxene with Fs20.9Wo1.6 (Fs20.4-21.9Wo0.7-2.0, n=22). Plagioclase is rare and has An7.6Or6.7 (An6.9-9.0Or5.3-7.9, n=5), feldspathic glass with wide range of composition: up to An30Or15 (An8.2-24.7Or2.9-15.5, n=10). Submicrometer diopside crystallites in glass with Fs8.4Wo46.1 (Fs6.3-11.6Wo44.8-48.3, n=3). Among opaque minerals, the major one is taenite with 33.4 wt% Ni (29.9-36.5, n=11) and 0.22 wt% Co (0.12-0.45 wt%). Kamacite has 6.63 wt% Ni (6.1-7.1 wt% Ni, n=9) and 0.72 wt% Co (0.49-0.85). Accessory minerals include troilite, mackinawite with (Fe,Ni)/S=1.1, chromite, ilmenite, Cl-apatite (with up to 5wt% of Cl) and merrillite (up to 2.5 wt% Na2O and 3.5 wt% MgO).
