چکیده

Major element studies of fluid inclusions in fibrous and cloudy diamonds reveal that most inclusions trapped high density fluids (HDFs) with a wide range of composition. The compositions fall along two arrays between three end-members: carbonatitic to hydroussilicic and carbonatitic to hydrous-saline. Recent studies of diamonds from Siberia and Kankan (Navon et al., 2008; Weiss et al., 2008) further subdivided the carbonatitic HDFs into: high-Mg and low-Mg groups.

Constraints on source-forming processes of West Greenland kimberlites inferred from Hf-Nd isotope systematics

Kimberlites from West Greenland have Hf–Nd isotope as well as major and trace element compositions that are similar to other Group I kimberlites, but that are distinctive in the spectrum of magmas sampled at Earth’s surface. The West Greenland kimberlites have eNdi that ranges from +1.6 to +3.1 and eHfi that ranges from 4.3 to +4.9. The samples exhibit ubiquitous negative DeHfi (deviation from ...

Geochemistry of South African On- and Off- craton, Group I and Group II Kimberlites: Petrogenesis and Source Region Evolution

Bulk-rock geochemical compositions of hypabyssal kimberlites, emplaced through the Archaean Kaapvaal craton and Proterozoic Namaqua–Natal belt, are used to estimate close-to-primary magma compositions of Group I kimberlites (Mg-number 1⁄4 0 82–0 87; 22–28 wt % MgO; 21–30 wt % SiO2; 10–17 wt % CaO; 0 2–1 7 wt % K2O) and Group II kimberlites (Mgnumber 1⁄4 0 86–0 89; 23–29 wt % MgO; 28–36 wt % SiO...

What olivine, the neglected mineral, tells us about kimberlite petrogenesis

We report here the results of a petrographic and geochemical study of remarkably well-preserved kimberlites from the Kangamiut region in Greenland. The samples contain between 5 and 45% of olivine in the form of rounded “nodules”, each 1 to 5 mm in diameter. Most originally were single crystals but many consist of polycrystalline, monomineralic aggregates. Olivine compositions vary widely from ...

Kimberlites and Lamproites: Primary Sources of Diamond

INTRODUCTION A variety of mantle-derived igneous rocks comprise the primary sources of diamond, with the principal hosts being kimberlite and lamproite. Primary diamonds or graphite pseudomorphs after diamond are also known to occur in some lamprophyres (Jaques, Kerr et al., 1989), alkali basalts and alpine type peridotites (Kaminskii, 1984). Significant quantities of diamond have not yet been ...
